New thermoplastic insulation for track-resistant overhead cables with improved properties

Abstract

Non-shielded overhead cables have been installed for a long time in different variations. This paper describes the development of a fully thermoplastic insulation system that is suitable for a 90 °C conductor temperature. This has all of the advantages of a cross-linked system, better track resistance than an XLPE insulated cable yet none of the disadvantages like a longer production process.
