Abstract
The multilayer structure consisting of alternative sheets of paper and ethylene-propylene elastomers was investigated for electrical applications. The changes in the main electrical characteristics, namely volume resistivity, dielectric loss, permittivity were determined for the evaluation of material stability under accelerated degradation promoted by g irradiation. The satisfactory response of this sandwich structure is illustrated by sample resistivity placed around 1015 W.m, permittivity less 2.025 and dielectric loss not higher than 0.04. The correlation between degradation effects and electrical properties is presented. Keywords: electrical insulation, synthetic rubber, cellulose, multilayer structure
