Polyolefin compounds for cable and wire insulations

摘要

A number of requirements are made of polyolefin componds for cable and wire insulations and/or field-limiting layers. The novel polyolefin compounds should firstly have a long shelf life and secondly give electrical insulations having an ECT-retardant action and low dielectric losses. According to the invention, the polyolefin compounds contain ECT-retardant additives in the form of products of the polycondensation of a carbonyl compound and a carbocyclic and/or heterocyclic phenol having a thermal stability of >/= 200@C. Medium- and high-voltage cables.
