Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	NOTE A – BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of Preformed Line Products Company and subsidiaries (the “Company” or “PLPC”) have been prepared in accordance with United States of America (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from these estimates. In the opinion of management, these consolidated financial statements contain all estimates and adjustments, consisting of normal recurring accruals, required to fairly present the financial position, results of operations, and cash flows for the interim periods. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full-year ending December 31, 2022. Noncontrolling interests are presented in the Company’s consolidated financial statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in the Company’s consolidated financial statements. Additionally, the Company’s consolidated financial statements include 100 % of a controlled subsidiary’s earnings, rather than only its share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. The Consolidated Balance Sheet at December 31, 2021 has been derived from the audited consolidated financial statements but does not include all of the information and notes required by U.S. GAAP for complete financial statements. For further information, refer to the consolidated financial statements and notes to consolidated financial statements included in the Company’s 2021 Annual Report on Form 10-K filed on March 4, 2022 with the Securities and Exchange Commission. Certain prior year amounts have been reclassified to conform to the current year presentation. Recent accounting pronouncements and new accounting standards to be adopted The Company considers the applicability and impact of all ASUs. In October 2021, the Financial Accounting Standards Board ("FASB") issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Liabilities from Contracts with Customers.” This ASU requires an acquiring entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The ASU is effective for fiscal years and interim periods beginning after December 15, 2022, with early adoption permitted. The Company is evaluating the impact of adopting this ASU. No other recently issued or effective ASUs had, or are expected to have, a material impact on the Company's results of operations, financial condition or liquidity.

Revenue from Contract with Customer [Abstract]
Revenue	NOTE B – REVENUE Revenue recognition Sales are recognized when obligations under the terms of the contract are satisfied and control of promised goods or services has transferred to our customers. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services and is primarily based on shipping terms. Sales are measured as the amount of consideration the Company expects to receive in exchange for transferring products. Disaggregated revenue The Company’s revenues by segment and product type are as follows: Three Months Ended March 31, 2022 Product Type PLP-USA The Americas EMEA Asia-Pacific Consolidated Energy 56 % 72 % 54 % 65 % 59 % Communications 40 26 38 3 33 Special Industries 4 2 8 32 8 Total 100 % 100 % 100 % 100 % 100 % Three Months Ended March 31, 2021 Product Type PLP-USA The Americas EMEA Asia-Pacific Consolidated Energy 57 % 74 % 60 % 72 % 63 % Communications 38 22 33 5 29 Special Industries 5 4 7 23 8 Total 100 % 100 % 100 % 100 % 100 % Credit losses for receivables The Company maintains an allowance for credit losses for estimated losses resulting from the inability of its customers to make required payments. The Company uses a current expected credit loss model in order to immediately recognize an estimate of credit losses that are expected to occur over the life of the financial instruments, mainly trade receivables. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns and other analyses of historical data trends. Receivable balances are written off against an allowance for credit losses after a final determination has been made. The change in the allowance for credit losses includes expense and net write-offs, which are identified in the following table: Three Months Ended March 31 2022 2021 Allowance for credit losses, beginning of period $ 3,091 $ 2,848 Additions charged to costs and expenses 723 252 Write-offs ( 133 ) ( 124 ) Foreign exchange and other 54 ( 79 ) Allowance for credit losses, end of period $ 3,735 $ 2,897

An actual valuation of inventories under the LIFO method can be made only at the end of the year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs. Because these estimates are subject to change and may be different than the actual inventory levels and costs at the end of the year, interim results are subject to the final year-end LIFO inventory valuation. During the three-month periods ended March 31, 2022 and 2021, the net change in LIFO inventories resulted in expense of $ 1.3 million and $ 0.5 million, respectively, to Costs of products sold. Property, plant and equipment – net Major classes of Property, plant and equipment are stated at cost and were as follows: March 31, 2022 December 31, 2021 Land and improvements $ 19,840 $ 21,039 Buildings and improvements 100,260 99,403 Machinery, equipment and aircraft 211,028 204,945 Construction in progress 15,765 10,605 346,893 335,992 Less accumulated depreciation ( 190,459 ) ( 186,218 ) $ 156,434 $ 149,774 Legal proceedings The Company can be party to a variety of pending legal proceedings and claims arising in the normal course of business, including, but not limited to, litigation relating to employment, workers’ compensation, product liability, environmental and intellectual property. The Company has liability insurance to cover many of these claims. Although the outcomes of these matters are not predictable with certainty, the Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the event the Company determines that a loss is not probable, but is reasonably possible, and the likelihood to develop what the Company believes to be a reasonable range of potential loss exists, the Company will include disclosure related to such matters. To the extent that there is a reasonable possibility the losses could exceed amounts already accrued, the Company will adjust the accrual in the period in which the determination is made, disclose an estimate of the additional loss or range of loss and if the amount of such adjustment cannot be reasonably estimated, disclose that an estimate cannot be made. As of March 31, 2022 and December 31, 2021, the Company has accrued approximately $ 2.2 million and $ 2.3 million, respectively, representing its best estimate for losses to be incurred on global legal matters. The Company and its subsidiaries Helix Uniformed Ltd. (“Helix”) and Preformed Line Products (Canada) Limited (“PLPC Canada”), were each named, jointly and severally, with each of SNC-Lavalin ATP, Inc. (“SNC ATP”), HD Supply Canada Inc., by its trade names HD Supply Power Solutions and HD Supply Utilities (“HD Supply”), and Anixter Power Solutions Canada Inc. (the corporate successor to HD Supply, “Anixter” and, together with the Company, PLPC Canada, Helix, SNC ATP and HD Supply, the “Defendants”) in a complaint filed by Altalink, L.P. (the “Plaintiff”) in the Court of Queen’s Bench of Alberta in Alberta, Canada in November 2016 (the “Complaint”). The Complaint states that the Plaintiff engaged SNC ATP to design, engineer, procure and construct numerous power distribution and transmission facilities in Alberta (the “Projects”) and that through SNC ATP and HD Supply (now Anixter), spacer dampers manufactured by Helix were procured and installed in the Projects. The Complaint alleges that the spacer dampers have and may continue to become loose, open and detach from the conductors, resulting in damage and potential injury and a failure to perform the intended function of providing spacing and damping to the Project. The Plaintiff is seeking an estimated $ 56.0 million Canadian dollars in damages jointly and severally from the Defendants, representing the costs of monitoring and replacing the spacer dampers and remediating property damage, due to alleged defects in the design and construction of, and supply of materials for, the Projects by SNC ATP and HD Supply/Anixter and in the design of the spacer dampers by Helix. The Company believes the claims against it are without merit and intends to vigorously defend against such claims. The Company is unable to predict the outcome of this case, however, it has recorded a reserve for the low end of the range for potential loss associated with this matter. If this matter is concluded in a manner adverse to the Company, it could have a material effect on the Company’s financial results. The Company is not a party to any other pending legal proceedings that the Company believes would, individually or in the aggregate, have a material adverse effect on its financial condition, results of operations or cash flow. Insurance Settlement On January 2, 2022, Director Emeritus Barbara P. Ruhlman passed away at the age of 89. Mrs. Ruhlman was member of the Company’s Board of Directors from 1988 to 2016, at which time she elected to resign and was appointed as the Company’s Director Emeritus. Mrs. Ruhlman was the daughter of the Company’s founder, Thomas F. Peterson, and was the mother of the Company’s current Chief Executive Officer, Robert G. Ruhlman. A Company-owned life insurance policy was maintained for Mrs. Ruhlman until her death. During the period ended March 31, 2022, the Company received approximately $ 6.9 million in cash proceeds and recorded a gain of approximately $ 4.4 million in Other income – net, related to the settlement of this insurance policy.

Computation of Earnings Per Share	NOTE G – COMPUTATION OF EARNINGS PER SHARE Basic earnings per share were computed by dividing Net income by the weighted-average number of common shares outstanding for each respective period. Diluted earnings per share were calculated by dividing Net income by the weighted-average of all potentially dilutive common stock that was outstanding during the periods presented. The calculation of basic and diluted earnings per share for the three months ended March 31, 2022 and 2021 was as follows: Three Months Ended March 31 2022 2021 Numerator Net income $ 12,285 $ 7,179 Denominator Determination of shares Weighted-average common shares outstanding 4,928 4,917 Dilutive effect – share-based awards 15 19 Diluted weighted-average common shares outstanding 4,943 4,936 Earnings per common share Basic $ 2.49 $ 1.46 Diluted $ 2.49 $ 1.45 For the three months ended March 31, 2022 and 2021 , 23,000 and 15,000 stock options, respectively, were excluded from the calculation of diluted earnings per share as the effect would have been anti-dilutive.

Amortization expense is estimated to be $ 1.9 million for the remainder of 2022, $ 1.9 million for 2023, $ 1.8 for 2024, $ 1.7 million for 2025 and $ 1.6 million for 2026. The combined weighted-average remaining amortization period is approximately 12.3 years. The weighted-average remaining amortization period by intangible asset class is as follows: land use rights, 53.3 years; trademarks, 11.7 years; technology, 8.9 years; and customer relationships, 10.9 years. The Company’s measurement date for its annual impairment test for goodwill is October 1st of each year. The Company performs additional interim impairment assessments as circumstances warrant. The Company may use both quantitative and qualitative approaches when testing goodwill for impairment. For selected reporting units where the qualitative approach is utilized, a qualitative evaluation of events and circumstances impacting the reporting unit is performed to determine if it is more likely than not that the fair value of the reporting unit exceeds its carrying amount. If that determination is made, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test on the reporting unit. For the quantitative approach, the Company uses a combination of the income approach, which uses a discounted cash flow methodology, and the market approach, which uses comparable market multiples in computing fair value by reporting unit. The Company then compares the fair value of the reporting unit with its carrying value to assess if goodwill has been impaired. The fair value estimates are subjective and sensitive to significant assumptions, such as revenue growth rates, operating margins, the weighted-average cost of capital, and estimated market multiples, of which are affected by expectations of future market or economic conditions. The Company believes that the methodologies, significant assumptions, and weightings used are reasonable and result in appropriate fair values of the reporting units. Given the continued decline in the Company’s results in the Asia-Pacific region and the uncertainty surrounding COVID-19 including the lingering impacts of the numerous variants, the Company concluded that an indicator of impairment was present and conducted an interim impairment review of its goodwill in the Asia-Pacific reporting unit as of September 30, 2021. Based on the interim impairment assessment and annual assessment at October 1, 2021, the Asia-Pacific reporting unit’s fair value exceeded its carrying value by approximately 10 %. The Company re-evaluated the results of its Asia-Pacific region at March 31, 2022 and did not identify additional impairment indicators. The Company will continue to evaluate the results of its Asia-Pacific region and conduct interim testing if additional impairment indicators are present in future quarters. At March 31, 2022, the Asia-Pacific reporting unit's goodwill was $ 7.5 million. No indicators of impairment were identified for the Company's other reporting units. The Company’s only intangible asset with an indefinite life is goodwill. The changes in the carrying amount of goodwill, by segment, for the three months ended March 31, 2022 are as follows: USA The Americas EMEA Asia-Pacific Total Balance at January 1, 2022 $ 3,078 $ 4,244 $ 13,561 $ 7,311 $ 28,194 Additions 0 5,195 3,912 0 9,107 Currency translation 0 1,068 ( 102 ) 168 1,134 Balance at March 31, 2022 $ 3,078 $ 10,507 $ 17,371 $ 7,479 $ 38,435 The 2022 additions to goodwill relate to the acquisitions of Maxxweld Conectores Eletricos Ltda. and Holplast, s.r.o.

Fair Value Disclosures [Abstract]
Fair Value of Financial Assets and Liabilities	NOTE I – FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES The Company measures and records certain assets and liabilities at fair value. A fair value hierarchy is used for those assets and liabilities measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of the following three levels: Level 1 Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets. Level 2 Inputs other than Level 1 inputs that are either directly or indirectly observable, which may include: o Quoted prices for similar assets in active markets; o Quoted prices for identical or similar assets or liabilities in inactive markets; o Inputs other than quoted prices that are observable for the asset or liability; and o Inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 Inputs to the valuation methodology are unobservable and developed using estimates and assumptions developed by the Company which reflect those that a market participant would use. The following table summarizes the Company’s assets and liabilities, recorded and measured at fair value, on the Company’s Consolidated Balance Sheets as of March 31, 2022 and December 31, 2021: Description Balance as of Quoted Prices in Significant Other Significant Assets: Foreign currency forward contracts $ 411 $ 0 $ 411 $ 0 Total Assets $ 411 $ 0 $ 411 $ 0 Liabilities: Supplemental profit sharing plan $ 6,909 $ 0 $ 6,909 $ 0 Total Liabilities $ 6,909 $ 0 $ 6,909 $ 0 Description Balance as of Quoted Prices in Significant Other Significant Assets: Foreign currency forward contracts $ 534 $ 0 $ 534 $ 0 Total Assets $ 534 $ 0 $ 534 $ 0 Liabilities: Supplemental profit sharing plan $ 8,633 $ 0 $ 8,633 $ 0 Total Liabilities $ 8,633 $ 0 $ 8,633 $ 0 The Company operates internationally and enters into intercompany transactions denominated in foreign currencies. Consequently, the Company is subject to market risk arising from exchange rate movements between the dates when foreign currency transactions occur and the dates they are settled. The Company currently uses foreign currency forward contracts to reduce the risk related to some of these transactions. These contracts usually have maturities of 90 days or less and generally require an exchange of foreign currencies for U.S. dollars at maturity at rates stated in the contracts. These contracts are not designated as hedging instruments under U.S. GAAP. Accordingly, the changes in the fair value of the foreign currency forward contracts are recognized in each accounting period in Other operating expense - net on the Consolidated Statements of Income together with the transaction gain or loss from the related balance sheet position. For the three months ended March 31, 2022 and 2021 , the Company recognized a net loss of $ 2.1 million and a net gain of $ 0.3 million, respectively, on foreign currency forward contracts. The Company has a non-qualified Supplemental Profit Sharing Plan for its executives and directors. The liability for this unfunded Supplemental Profit Sharing Plan was $ 6.9 million and $ 8.6 million at March 31, 2022 and December 31, 2021 , respectively. These amounts are recorded within Other noncurrent liabilities on the Company’s Consolidated Balance Sheets. The Supplemental Profit Sharing Plan allows participants the ability to hypothetically invest their proportionate award into various investment options, which primarily include mutual funds. The Company credits earnings, gains and losses to the participants’ deferred compensation account balances based on the investments selected by the participants. The Company measures the fair value of the Supplemental Profit Sharing Plan liability using the market values of the participants’ underlying investment accounts.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE K – INCOME TAXES The Company’s effective tax rate was 13 % and 32 % for the three months ended March 31, 2022 and 2021, respectively. The lower effective tax rate for the three months ended March 31, 2022 compared to the U.S. federal statutory rate of 21 % was primarily the result of a non-taxable benefit of $ 4.4 million related to the proceeds from a settlement of a Company-owned life insurance policy that was maintained for Director Emeritus Barbara P. Ruhlman until her death in January 2022, as well as other favorable discrete items. In addition to the aforementioned benefits, the effective tax rate decreased for the first quarter of 2022 compared to the first quarter of 2021 due to a decrease in unfavorable permanent adjustments in 2022, primarily related to the impact of lower operating results in certain jurisdictions. The Company provides valuation allowances against deferred tax assets when it is more likely than not that some portion or all of its deferred tax assets will not be realized. During the period ended March 31, 2022, the Company recorded additional valuation allowances in various jurisdictions on their deferred tax assets, that are not expected to be realizable. For the three-month period ending March 31, 2022, the Company did no t record any unrecognized tax positions.

Other intangible assets of $ 4.4 million include customer relationships, tradenames and backlog. The preliminary estimated fair values of the customer relationships, trademarks and technology intangible assets of $ 4.0 million, $ 0.2 million and $ 0.2 million, respectively, were determined using either the relief-from-royalty model or the multi-period excess earnings model, which are discounted cash flow models that rely on the Company's estimates. These estimates require judgment of future revenue growth rates, future margins, and the applicable weighted-average cost of capital used to discount those estimated cash flows. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. The estimated useful lives for customer relationships, trademarks and backlog were 15 years , 20 years , and 1 year , respectively.
