  • Electrical lines
    Patent number: 9117571
    Abstract: 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 4,000M?km. The shield (7) is composed of a non-woven fabric on the basis of polyamide which. is rendered electrically conductive through metallization.
