Cold Shrink QS2000E Cable Jointing Kits
All 3M cold shrink products include built in components to ensure excellent insulation and stress control. With peace of mind and reliability top of our
agenda; unlike heat shrink alternatives, a molecular permanent set ensures constant radial pressure is exerted on the cable for the duration of the cable
joints’ life. Additionally, many of the joint bodies are comprehensively factory tested before release - something simply not possible with heat shrink due
to its material nature. Finally, as a result of continuous development and refinement over more than 40 years, only 3M can offer you such a choice in
cold shrink technology in terms of product cost and flexibility in its application.
Standard 3M Cold Shrink Joints with Taped Electrode
The 3M cold shrink taped electrode splice offers a viable cost-based alternative to heat shrink cable jointing technology. The range covers many of the
most common cable configurations and size ranges. The electrode in this case is built up by the jointer using Scotch
