Heat Shrinkable Wraparound Jacket Repair Sleeve
Heat Shrinkable Wraparound System for Plastic or Metal Sheathed Cable Repair &RE-Jacketing of powercable Joint
CRS heat shrink wraparound sleeves are manufactured from thermally stabilized cross-linked polyolefin, with a hotmelt adhesive liner on the inner side of the sleeves. Upon heating, the sleeve shrinks and the adhesive melts, creating a water tight bond between the sleeve and cable sheath or cable Joint assembly components. CRS wraparound sleeve meat & even exceed the various national & international quality standards applicable. A corrosion proof stainless steel channel is used to close the sleeve during installation.
CRS heat shrinkable wraparound sleeves are designed to repair damaged cable sheath. It is also suitable for use for rejecting of cable Joints and as additional corrosion protection on undamaged cables.
Quick & easy to apply, it provides maximum protection againstcorrection& waterproof.
Heat shrinkable adhesive lined wrap around sleeve with stainless steel self locking channel, primarily used for outer sheath repair for power cables of any voltage class & re-jacketing of straight through cable Joints.
CRS wraparounds are a fast and permanent cable repair and sealing system. The repair sleeve is quickly fitted in place by means of its rail and channel closure. A moisture-proof, insulating and tight-fitting repair is then obtained in one step by heating, which makes the sleeve diameter shrink and the adhesive coating melt and flow into interstices.
Because of its heat-shrink phenomena, each size of heat shrinkable wraparound sleeve size will fit several different cable diameters. The adhesive provides excellent bonding and sealing characteristics to all materials commonly used in the various cable insulation and sheath constructions, such as plastic, rubber, lead, paper, aluminum & copper.
This sleeve after installation provides corrosion protection to steel armouring and water-tight seal around the sheath & cable Joint assembly.
A stainless steel channel closure system slide over rails on the sleeve, keeps the wraparound in place during installation but can easily be removed when the adhesive has set (if desired)
