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.
3M™ Cold Shrink QT-III 7640-S & 7650-S Series Termination Kit is designed for terminating medium voltage cables. The UV stable, erosion and track-resistant, silicone rubber construction makes the termination suitable for outdoor applications. The lower surface stress, high dielectric-constant material offers an optimized BIL performance while ensuring a leak-proof, compact fit. A jumper wire-top insulator provided on the detachable core allows for convenient installation while offering optimal protection of a circuit from corrosion and animal damages.
