3M™ Cold Shrink QT-III 7640-S Series Termination Kit includes sufficient material to make 1 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 allow the termination to withstand voltages up to 15 kV.

3M™ Cold Shrink QT-III 7640-S Series Termination Kit is designed for terminating medium-voltage power cables. The track-resistant, silicone rubber insulation of the termination has a hydrophobic property that offers 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.
