Product name:
27/54-100mm Installation High Voltage Cold Shrink Indoor Terminal 1kv Silicone Rubber
Description:
Cold shrink tubing covers low-voltage cable, wire connections, joints, and terminals, and it shrinks when the core is removed to create tightly sealed bundles. It doesn't require heat guns, so it can be used where gas and electrical heating devices are not allowed. It is used across a wide variety of applications to provide electrical and mechanical protection against environmental damage.
Features:
1. Adopt self-developed cold shrink expansion technology combining with spiral supporting tube to avoid cracking
2. Adopt non-magnetic constant force spring to permanent connect to ensure a good contact for long period.
3. Great expansion rate, long storage period after expansion, big and lasting pressing force on mating interface, avoid retraction does not reach the designated position.
Applications
Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splices rated to 1000volts

Introduction:
EPDM Cold Shrink Tubes are a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core. They are supplied for field installation in this pre stretched condition. The core is removed after the tube has been positioned for installation over an in-line connection terminal link allowing the tube to shrink and form a waterproof seal. The insulating tube is made of EPDM rubber which contains no chlorides or sulphurs.
