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.
Features
• Excellent weather resistance, ultraviolet aging resistance and higher embrittlement resistance than heat
shrink tubing
• More resistant to slab and prick, abrasion, acid and alkali than silicone cold shrink tubing
• Simultaneously expands and shrinks with workpieces without clearances, seals tight in harsh
environment
• Stably sealing the workpieces in windy environment
• Well suited for cable less than 1KV
• Seals tight, retains its resiliency and pressure even after prolonged years of ageing and exposure
• Simple, safe installation, requires no tools or special training. No torches or heat work required
• Diameter shrinkage:±50%
• Sealing class IP68
