3M™ Cold Shrink QT-III 7620-S, 7680-S & 7690-S Series Termination Kits include three 1-piece, skirted terminations. Each kit has materials to make 3-single phase terminations for tape shield, wire shield and UniShield® power cables.
3M™ Cold Shrink QT-III 7620-S, 7680-S & 7690-S Series Termination Kits are designed for terminating solid dielectric shielded, medium-voltage power cables. The QT-III termination uses high dielectric constant (High-K) stress control mastic insulated with a molded UV-stable, track-resistant, silicone insulator. The track resistant, hydrophobic propertities of the silicone rubber minimize leakage currents. Meets the requirements of IEEE Standard 48, for Class 1 for outdoor, weather-exposed environments.
