Product Introduction
The self-shrinkable insulation cover is designed for 22.9kV extra-high voltage jumper wire connection sleeves where no tension is applied. It uses a round silicone rubber insulator and a one-touch PP spiral core to contract from both sides, preventing moisture ingress and resisting sunlight-induced degradation of insulating properties. With a lightweight 2kg insulation stick, it improves installation ease, reduces musculoskeletal strain, shortens work time by eliminating conventional insulation taping, and ensures superior construction quality, safety, and convenience.
