Heat-shrinkable wraparound sleeves for cable repair
Wraparound Cable Repair Sleeve
Heat Shrink Cable Repair Sleeve
CRS Wraparound sleeve is mainly used for repairing outer/inner sheath/core damages on a HV cable and LV cable. It is made from cross-linked polyolefin which equals or exceeds the material properties of the original cable jacket. They can also be used for protecting against corrosion on metallic parts of the cable that are exposed to the outside.
Features:
Material: cross-linked polyolefin, inner coated with hot-melt adhesive
Standard color: black
Highlights: easy operation, wide range of selection, fit every occasion, excellent water repellency
Operating temperature:-40~+65℃
Shrink temperature:200℃
