Study on the aging characteristics of silicone rubber materials for composite insulators

Autor: Xie Pengkang, Ning Kai

Publikováno v: E3S Web of Conferences, Vol 242, p 02002 (2021)

The electron beam radiation method is emitted by electronic accelerators, which can change the chemical physical properties of radiation. Silicone rubber samples after different irradiation intesities were carried out for the 1000h aging test, and th
