Heat Shrink Anti-Tracking Rain Shed
Request a Quote
This heat shrink anti-tracking rain shed is used for extending the creepage path for cable terminations. It is made of quality polyolefin that ensures excellent insulation performance. In addition, adhesives are smeared along the inner wall to deliver outstanding sealing performance. The anti-tracking rain shed is applicable for switch-gear and low-to-high voltage equipment, since it can avoid tracking, outdoor pollution flashover and creepage.
In WOER, two types of rain sheds are supplied, one with a tilted surface, or WRSSQ, and the other with a flat surface, or WRSRS.
