Heat Shrink Cable End Cap (INSULCAP GEC Series)

About Heat Shrink Cable End Cap (INSULCAP GEC Series)

A cut cable end lets water and moisture travel into the conductor and insulation, whether the cable is on a drum in the yard, waiting in a trench or left as a spare end after jointing. The Gala INSULCAP end cap closes that end permanently.

The cap is a closed-end moulding of cross-linked polyolefin, supplied expanded, with a hot-melt adhesive lining inside. When heated it shrinks onto the cable sheath and the adhesive melts into the irregularities of the jacket, forming a watertight seal. It suits XLPE, PVC, PILC and rubber-sheathed cables.

Fitting takes a few minutes: cut the cable end straight, remove any serving and armour, clean and degrease the sheath, push the cap over the end and shrink it with a propane (preferred) or butane torch, working from the closed end towards the cable until adhesive shows at the open end. The cap recovers above 125 deg C. Let it cool before the cable is handled.

Sizes are chosen by cable outside diameter: each code covers a cable range, and most sizes come in a standard and a long version, plus A versions for a wider range. The smallest cap fits 2.5 mm cable and the largest takes cables up to 460 mm across, so one family covers control cables, LV and MV power cables and large multicore cables on export drums.

Related Gala caps are listed separately: end caps with a cable pulling eye, de-gassing caps with a relief valve, caps with a pressure valve, conductive caps, live end cap kits and tamper-proof printed caps. Gala is an ISO 9001, ISO 14001 and ISO 45001 certified manufacturer.
