3M™ Cold Shrink QT-III 7640-S & 7650-S Series Termination Kit includes a skirted termination with a jumper wire-top insulator. It ensures a pliable, tight seal for jacketed concentric neutral and concentric neutral power cables. The conjunction of high dielectric-constant material and sealing compounds allows the termination to withstand voltages of 5 to 25/28 kV.
For polymeric power cable systems, use 3M™ Cold Shrink Termination QT-III. Our termination kits are designed for power cables with copper wire screen according to HD 620 (IEC 60502) and cover a wide application range. They feature a prefabricated one-piece cold shrink termination body, which allows fast and easy installation on a wide range of cable types and sizes, at temperatures ranging from -20 °C to +50 °C. No heat/flame or special tools are required for the installation. 3M™ Cold Shrink Termination QT-III meets and exceeds the requirements of European Standard CENELEC HD 629.1 and IEC 60502-4.
