EPDM cold shrink cable joints

Description


EPDM cold shrink tube is a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core. Cold shrink cable joints is 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. Cold shrink cable joints 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.

Telsto Cold Shrink Splice Cover Kits are designed to be an easy-to-install, safe and fast method of covering splices on Spacer Cable. The tubes are open-ended rubber sleeves which are factory-expanded and assembled onto removable plastic cores. After the tube has been positioned for installation over an in-line splice, the core is removed, thus allowing the tube to shrink and seal the splice.

Features


1)Excellent weather resistance, ultraviolet aging resistance and higher embrittlement resistance than heat shrink tubing
2)More resistant to slab and prick, abrasion, acid and alkali than silicone cold shrink tubing

3)Simultaneously expands and shrinks with workpieces without clearances, seals tight in harsh environment

4)Stably sealing the workpieces in windy environment

5)Well suited for cable less than 1KV

6)Seals tight, retains its resiliency and pressure even after prolonged years of ageing and exposure.

7)Simple , safe installation, requires no tools or special training. No torches or heat work required

8)Diameter shrinkage:≥50%

9)Sealing class IP68
