3M Cold Shrink Technology
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 to its pre-stretched size and shrinks onto the cable, exerting constant radial pressure for the lifetime of the joint or termination.
• Simple, tool-free installation
• Constant radial pressure
• Extensive quality and factory testing programmes
• Lower installed cost - compared to many competitive products
• Installation without the need for a heat source
