Change Of Power Cables Properties Due To Various Aging Mechanism

Power cables with PVC based insulation blends are nowadays still one of the most applied types of cables. Usually, this kind of cables is used for 400 V transmission lines, but also for 6/10 kV voltage level. This paper deals with various degradation mechanisms and factors influencing this kind of cables in service. The analysis of this influence is focused on the feasible change of dielectric and mechanical properties of insulation material.
