3M Wraparound Heat Shrink Cable Repair HDCW sleeves is designed to quickly repair damaged cable jacketing. They may also be used to rejacket in-line splices. HDCW wrap sleeves can be used as insulation material on cable and splices up to 1000 V and as jacket repair material on cable up to 35 kV. The design of the wrap sleeve allows it to be installed in tight spaces with ordinary heating equipment such as a torch. The HDCW is made from modified cross-linked polyolefin, with a hot-melt adhesive liner on the inner side of the sleeve. Upon heating, the sleeve shrinks and the adhesive melts, creating a water-tight bond between the sleeve and the cable. HDCW Wraparound Cable Repair Sleeves meet ANSI C119.1 requirements. A corrosion proof metal channel is used to close the sleeve during installation. 3M Wrap Sleeves HDCW are stocked in four lengths and five diameters. Other cut lengths are available upon request.
