Resistive compounds based on chlorinated polyethylene

Chlorinated polyethylene has some unusual properties which have led to its use in specialized cable applications. In one of the more interesting of these, it serves as the base resin for resistive compounds for use as adherent screens to the insulation of "solid dielectric" high voltage cables. Specifically, it has led to the adoption of a new class of resistive compound, termed DRT, in which the mechanical characteristics at high temperatures lie intermediate between those of conventional thermoplastic and crosslinked compounds. This paper describes the range of chlorinated polyethylene resins best suited to this application and discusses the influence of various parameters on the characteristics of practical compounds. Reference is made to some experience in the commercial use of these compounds.
