Equivalent to EPDM Cold Shrink Tube 3m 105*457 Cold Shrinkable Sleeve for Electric Power Cable Insulation Protection

About Product

Highlight

RUBLS-EPDM 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 lug, etc., allowing the tube to shrink and form a waterproof seal. The insulation tube is made of EPDM rubber, which contains no chlorides or sulphurs. Various diameter sizes will cover a range of 1000 volt cables, copper and aluminum conductors
Compared with the heat shrink tube, it has better resistance to weather and ultraviolet aging, and does not brittle after long-term use
Compared with silicone rubber cold shrinkable pipe, more puncture resistance, wear resistance, acid and alkali resistance
It can synchronize thermal expansion and contraction with the workpiece in the harsh environment, without producing gaps and sealing tightly
Even in a state of wind sway, it can still breathe synchronously with the workpiece, and the sealing effect remains excellent
Suitable for power cables below 1KV and a wide range of specification, and can be used in indoors and outdoors, overhead, water or buried occasions
Strong toughness and rebound resilience, maintaining a constant radial pressure and providing a tight seal for the cable in the long run
Easy installation without heating or special tools and no need for hot melt adhesive or tape to strengthen the seal at the joint
Standard color: Black
