3M Cold Shrink
Cold shrink tubing and moulded parts for electrical installation
Invented over 40 years ago by 3M, 3M Cold Shrink Technology is designed to make cable insulating, termination and abandonment as simple as possible. The secret of 3M Cold Shrink technology lies inside it, in the form of a plastic coil. After the 3M Cold Shrink Tube has been placed over the joint or cable end, this inner spiral is pulled out. The insulating tube then contracts and seals onto the cable, exerting constant radial pressure for the lifetime of the joint or termination.
3M Cold Shrink Tubes are installed easily and reliably without the use of cable jointing tools (e.g. gas torches or naked flames). The Cold Shrink tubes manufactured by 3M Electrical are made from extruded EPDM (Ethylene-Propylene-Diene-Monomer) or silicone rubber that are stretched onto a spiral core.
The benefits of cold shrink tubes clear a long-term environmental seal that has high performance even in extreme conditions. The tool-free installation reduces downtime, installation time and training requirements.
