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.
²Excellent weather resistance, ultraviolet aging resistance and higher embrittlement resistance than heat shrink tubing
²More resistant to slab and prick, abrasion, acid and alkali than silicone cold shrink tubing
²Simultaneously expands and shrinks with workpieces without clearances, seals tight in harsh environment
²Stably sealing the workpieces in windy environment
²Well suited for cable less than 1KV
²Seals tight, retains its resiliency and pressure even after prolonged years of ageing and exposure.
²Simple , safe installation, requires no tools or special training. No torches or heat work required.
²Sealing class IP68
Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splices rated to 1000volts
²Meets ANSI C119.1, directly buriable or submersible
²For indoor, outdoor, or overhead use
²Physical protection and moisture sealing for high-voltage, air-insulated connectors and lugs such as spacer cable andlug connections to bus bar
²Insulation of secondary splices copper or aluminum conductors
²Relocation of service
²Dig-in repairs, sheath repairs
²Insulation of inline conductor transition connectors
²Sealing of coax cables with Type N or 7/16 DIN connectors on wireless communication towers
