3M™ Cold Shrink QT-III 7640-T & 7650-T Series Termination Kit includes a non-skirted, 1-piece termination. It ensures a pliable, tight seal for jacketed concentric neutral and concentric neutral power cables. The conjunction of high dielectric-constant material and silicone rubber insulation allows the termination to withstand voltages of 5 to 35kV.
3M™ Cold Shrink QT-III 7640-T & 7650-T Series Termination Kit is designed for terminating medium voltage cables. The track-resistant, silicone rubber insulation of the termination has a hydrophobic property and offers a long-lasting service life. The lower surface stress, high dielectric-constant material offers an optimized BIL performance while ensuring a leak-proof, compact fit. IEEE Standard 48 Class 1 Approved for indoor and weather-protected applications.
