Abstract

A composition for use as an electrical stress controlling layer (12) for use with cable joints and terminations has a non-linear V-I
characteristic. The composition comprises a polymeric matrix filled with doped zinc oxide varistor powder. The particulate filler is sieved at 125 micrometres, calcined at 1100 °C, and lightly ground to maintain the spherical shape of the particles. More than 50% by weight of the particles have a maximum dimension between 5 and 100 micrometres.
