product description:
Heat-shrinkable right-angle boots/straight boots are made of radiation cross-linked polyolefin light materials, coated with red anti-tracking and weather-resistant sealant, with excellent insulation, anti-electric carbon tracking, anti-ultraviolet, and weather resistance. They are widely used Power cables below 36 KV. Protect cables against flashovers and surges caused by transfer switches and transformers.
