US Patent 9117571 Electrical lines

An electrical line with at least two leads composed of conductors surrounded by insulation (4) is proposed, where the leads are stranded together and are surrounded by a common electrical shield above which is mounted a circumferential layer of insulation material. The insulation (4) of the leads is composed of a poorly compressible, cross-linked elastomer insulation material whose insulation resistance constant at room temperature is greater than 4,000MΩkm. The shield (7) is composed of a non-woven fabric on the basis of polyamide which. is rendered electrically conductive through metallization.
