3M Cold Shrink QT II 5620K & 5630K Series Termination Kits are designed for terminating solid dielectric shielded, medium voltage power cables. The QT II termination uses high dielectric constant (High K) stress control tube insulated with a 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.
