With the economy developed, environmental pollution is getting worse, and the situation of power substation insulation and protection is serious, especially for the old substation. Pollution flashover, rain flashover, line trip because of icing, small animals, and uncovered busbar, all caused damages and injury accidents. More and more power substations choose silicone rubber overhead line sleeves to insulate the substation.

The sleeves are made with a full-length extruded silicone rubber supplied in a reel in a flat format. The edge of the product is formed to lock together when installed on an electrical conductor. The installation requires dispensing silicone sealant in the lock and pressing the two ends together to lock, forming a circular cover over the bare. The sleeves are offered in thickness appropriate to voltage class for use up to 220KV.
