Product name:
IP68 grade cold shrink retractable tube for cell tower sealing kits1-2 cable to 4.3-10 connector
Description:
Cold shrink tubing is used to insulate wires, connections, joints and terminals in electrical work. It can also be used to repair wires, bundle wires together, and to protect wires or small parts from minor abrasion. It needs storage in controlled environments with temperatures not exceeding 43°C.
Features:
Simple and quick installation, without tools.
Custom sizes from 12 mm – 70 mm. Covers many different cable sizes.
Tighten the seal, even after many years, and keep the elasticity.
No mastic, tape or mold mass is needed.
No need for heating.
High resistance to fungi, acid, alkalis, ozone and UV radiation.
Easy to uninstall again.
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.
