Nexans (NEXNY) USPTO patentsUtility application

The invention relates to a cable comprising at least one electrically insulating layer obtained from a polymer composition comprising at least one polypropylene-based thermoplastic polymer material and at least one inorganic filler chosen from silicates, boron nitride, carbonates, and a mixture thereof, and to a process for preparing said cable.

A cable is provided having at least one elongated conductor surrounded by at least one cross-linked layer, said layer being obtained from a polymer composition comprising a polymer, a crosslinking agent, and an amine as co-crosslinking agent, wherein said amine has a nucleophilic value (N) of 14 or more.

The invention relates to a cable accessory, said accessory being surrounded by at least one electrically insulating crosslinked layer comprising at least one polymer material, boron nitride and silicon carbide, to an electrical device comprising at least said cable accessory, to a process for manufacturing said accessory and said device, to the use of said crosslinked layer around an electric cable accessory or in an electrical device, in particular for promoting heat discharge, to a kit for connecting electric cables, and to a cable accessory, said accessory comprising two fillers of different thermal conductivities.

The present invention relates to a composite material based on aluminium and alumina, its method of manufacture, and a cable comprising said composite material as an electrical conductor element.
