Cold shrink tubes are insulated, open‑ended rubber sleeves factory expanded and assembled onto removable plastic cores. After positioning over an inline connection, coupling cable, or termination, the core is removed, allowing the tube to shrink and form a water resistant seal. Made of liquid silicone rubber.
Where cold shrink tubing is used
Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splices rated to 1000V.
Physical protection and moisture sealing for high voltage, air insulated connectors and lugs.
For indoor, outdoor, in cable tray or overhead use.
