Heat Shrink Cable Repair Sleeve - Adhesive Lined Wraparound (GMRS)

About Heat Shrink Cable Repair Sleeve - Adhesive Lined Wraparound (GMRS)

When a cable's outer sheath is cut, scraped or crushed, the usual fixes mean cutting the cable or shutting the circuit down. Gala's Heat Shrink Cable Repair Sleeve (GMRS) avoids both. It is a flat sheet of cross-linked polyolefin with a hot-melt adhesive layer. It is wrapped round the damaged section where the cable lies, the overlap is closed, and the sleeve is heat-shrunk so that it tightens onto the cable while the adhesive melts and seals the damage. The result is a permanent waterproof barrier and mechanical protection over the repaired length.

Typical jobs are repairing damaged cable jackets, retrofitting protection over existing connections, repairing frayed cables and connectors in confined or underground spaces, and covering cable-to-conduit transitions and bundles of cable, wire or rope. It is used on communication, power, utility, industrial, shipboard and offshore cables.

Installation: roughen and degrease the cable jacket and the sleeve's inner overlap, wrap the sleeve so that the damage sits opposite the overlap, close the overlap, then shrink with a gas torch from the centre towards the edges until adhesive comes out at both ends, rolling out any wrinkles while hot.

Nine sizes cover cable outside diameters from 5 mm to 192 mm. Smaller sizes come in 100, 200 or 300 mm lengths, larger ones in 300 or 400 mm, with a minimum overlap of 25 to 75 mm. Custom dimensions are available on request. Stocking a few sizes covers most repair needs.
