3M™ Cold Shrink QT-III 7640-T & 7650-T Series Termination Kit includes a non-skirted, 1-piece 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 allows the termination to withstand voltages of 5 to 35kV.
3M™ Cold Shrink QT-III 7640-T & 7650-T Series Termination Kit is designed for terminating medium voltage cables. The 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: 700-1500 kcmil · 8 kV: 600-1250 kcmil · 15 kV: 500-1000 kcmil This termination is compatible with the following lugs: QL2-A-4/0-600, for conductor range: 500 kcmil (15kV) QL2-A-350-750, for conductor range: 500-750 kcmil (15kV)
