3M Cable Joints Terminations - Cold Shrink Scotchcast LV MV HV

Cable Joints & Terminations

Cable joints and terminations manufactured by 3M are used to repair damaged cables, replace cable fault sections, extend existing cable circuits and connect cable ends for termination onto electrical equipment bushings in switchgear and transformers, including 11kV and 33kV power cables operating at medium/high voltages (MV HV).

3M solutions include Cold Shrink and Scotchcast Resin joints – 3M products provide LV-HV permanent, durable and watertight cable seals, joints and terminations with excellent electrical insulation and unrivalled performance.

3m Cold Shrink

Cold Shrink was invented by 3M over 40 years ago to avoid the need for a heat source or naked flames in hazardous areas; however, cold shrink products have developed to replace traditional cable jointing methods of cast resin and heat shrink in many industrial applications.

The narrow smooth profile design of the 3M cold shrink EPDM tube allows more cables to be bunched together on cable tray, or in cable duct, without the problem of snagging, allowing for both horizontal and vertical jointing of cables. Cold shrink tubes and 3M technology are applied to cable joints, terminations, end caps and abandonment kits for low, medium (11kV-33kV) and high voltage cables (66kV-132kV).

Cold shrink terminations ensure the safest and quickest installation for LV MV HV power cables – reduces cable jointer or installer error and the risk of cable damage caused by overheating of heat shrink, ideal for potentially explosive and hazardous areas in onshore and offshore oil, gas and petrochemicals industries.

Cold Shrink

Cold Shrink – simply remove the spiral by unwinding the pre-stretched tube from the expanded core to reduce installation time. There is no waiting period for the resin to cure before back-fill of cable trench and moving onto the next cable joint.

3m Scotchcast Resins

Scotchcast resins provide the most reliable electrical insulation for cable joint, repair and sealing applications where high strength and specialist application resins are required including high voltage, hazardous area, hydrocarbon resistant, halogen free and flame retardant.
