3M™ Cold Shrink QT-III 7640-S-INV & 7650-S-INV Series Inverted Termination Kit includes a single-conductor, skirted termination. 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 35kV.

3M™ Cold Shrink QT-III 7640-S-INV & 7650-S-INV Series Inverted Termination Kit is designed for terminating medium voltage cables in outdoor applications. The UV stable, track-resistant, silicone rubber insulation of the termination has a hydrophobic property and offers a long-lasting service life while minimizing leakage currents in wet conditions. The lower surface stress, high dielectric-constant material offers an optimized BIL performance while ensuring a leak-proof, compact fit. IEEE Approved.
