Abstract :
Polymer insulator has the advantage of light weight, high strength and high performance on antipollution. At the present, polymer insulator is being tested on AC transmission lines and a few DC transmission lines in Japan. This paper reports on the surface degradation and characteristics of leakage current on silicone rubber (SR) under DC(+) and AC artificial aging test (the Rotating Wheel Dip Test; RWDT), and leakage current characteristics of polymer phase-to-phase spacers subjected to DC(+) and AC coastal exposure tests
