China 8426 Series Cold Shrink Tube

Cold Shrink EPDM Rubber Tubing for Coaxial/Coax Cables
Company Profile

Description
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 insulating 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.
Unique Advantages
² 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
² Simultaneously expands and shrinks with workpieces without clearances, seals tight in harshenvironment
² Stably sealing the workpieces in windy environment
² Well suited for cable less than 1KV
² Seals tight, retains its resiliency and pressure even after prolonged years of ageing and exposure.
² Simple , safe installation, requires no tools or special training. No torches or heat work required.
² Diameter shrinkage:≥50%
² Sealing class IP68
