Electrical Insulation Property of Silicone Rubber Tube in High Elevations

Article Preview

Abstract:

Silicone rubber is a polymer with the chain molecule structure of Si-O bond [1]. At the environment of 1970 m elevation, the power frequency withstand voltage and condensation experiments will be tested by using two silicone rubber tubes with length of 300mm and 330mm, which lasts one minute, under 85kV. In the high potential test, the silicone rubber tube does not appear the flashover when the surface of tubes weren’t polluted. However, the test voltage increases to 70kV and the surface of the silicone rubber tube will appear flashover, when the tubes are plated in the condensation conditions. The high potential experiments indicate that the electrical insulation property of silicone rubber tube is seriously debated in the humidity environment.
