Descrição
HarshMet Cold Shrink EPDM Tube CPE Series
For Electrical, Telecom and Industrial Applications
Descrição
HarshMet Cold Shrink Tubes are 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. A wide range of diameter sizes and lengths will cover a range of 1000 volt cables, copper and aluminium conductors.
Features
Simple installation, requires only workman’s hands
Accommodates a wide range of cable sizes
No torches or heat required
Good thermal stability
Seals tight, retains its resiliency and pressure even after prolonged years of ageing and exposure
Excellent wet electrical properties
Improved tough rubber formulation to with stand rough backfilling
Resists fungus v Resists acids and alkalis
Resists ozone and ultraviolet light
Applications
Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splices rated to 1000 volts
Directly buriable or submersible
For indoor, outdoor, or overhead use
Physical protection and moisture sealing for high-voltage, air-insulated connectors and lugs such as spacer cable and lug connections to bus bar
Insulation of secondary splices copper or aluminium conductors
Relocation of service v Dig-in repairs
Sheath repairs
Insulation of inline conductor transition connectors
Sealing of jumper-to-feeder and jumper-to-equipment RF coax connections
