3M™ Cold Shrink QT-III 7620-S, 7680-S & 7690-S Series Termination Kit includes three 1-piece, 3-phase, skirted terminations. It ensures a pliable, tight seal for tape shield, wire shield and UniShield® power cables. The conjunction of high dielectric-constant material and silicone rubber insulation allows the termination to withstand voltages of 5 to 35kV.
3M™ Cold Shrink QT-III 7620-S, 7680-S & 7690-S Series Termination Kit is designed for terminating solid dielectric-shielded, 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. IEEE Standard 48 Class 1 Approved for outdoor, weather-protected applications. Conductor Size Range for · 5 kV: 300-500 kcmil · 8 kV: 250-500 kcmil · 15 kV: 2/0 AWG-300 kcmil · 25/28 kV: 2-4/0 AWG This termination is compatible with the following lugs: QL2-A-2-250, for conductor range: 2/0 AWG-250 kcmil (15kV), 2-4/0 AWG (25/28kV)
