3M™ Cold Shrink QT-III Silicone Rubber Termination Kit 7620-T and 7690-T Series contains one-piece, non-skirted, silicone rubber terminations, meets IEEE Standard 48 Class 1 for indoor and weather-protected applications. The kits are designed for terminating solid dielectric shielded power cable rated 5–35 kV, with tape shield, wire shield and UniShield® constructions.
3M™ Cold Shrink QT-III 7620-T & 7690-T Series Termination Kit is designed for terminating solid dielectric-shielded, medium voltage cables. The UV stable, track-resistant, silicone rubber insulation of the termination has a hydrophobic property and offers a long-lasting service life. 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 indoor and 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 · 35 kV: 2-2/0 AWGThis 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), 1/0-2/0 AWG (35kV)
