Accumulating of surface charge on insulation dielectrics will gradually cause electrical properties deterioration in the whole insulation system of electrical apparatus. In the field of high voltage technology in electrical engineering, polyimide (PI) occupies an utmost important position which requires insulating dielectrics to work in a steady condition under different working temperature of electrical...
Condensation problems in outdoor RMU exist widely at the area which has a hot and humid climate such as the south of China, resulting in the corrosion of the equipment in the RMU. Once the switch operation mechanism corrodes, it would cause the switch to act abnormally. What is worse, the insulation performance of the equipment will be reduced. Improving the ability of natural ventilation is a safe,...
