3M™ 054007-42433 QT-III 7660-S Cold Shrink Insulated Termination Kit With High-K Stress Relief, For Use With Concentric Neutral and Jacketed Concentric Neutral Cable, Silicone Rubber

Vendor Description

3M™ cold shrink QT-III 7640-S, 7650-S and 7660-S series termination kit includes a 1-piece, 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 silicone rubber insulation allows the termination to withstand voltages of 5 to 35 kV. 3M™ cold shrink QT-III 7640-S, 7650-S and 7660-S series termination kit is designed for terminating medium voltage power cables. 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.
