3M™ Cold Shrink QT-III 7640-S & 7650-S Series Termination Kit includes a skirted termination with a jumper wire-top insulator. It ensures a pliable, tight seal for jacketed concentric neutral and concentric neutral power cables. The conjunction of high dielectric-constant material and sealing compounds allows the termination to withstand voltages of 5 to 25/28 kV.
3M™ Cold Shrink QT-III 7640-S & 7650-S Series Termination Kit is designed for terminating medium voltage cables. The UV stable, erosion and track-resistant, silicone rubber construction makes the termination suitable for outdoor applications. The lower surface stress, high dielectric-constant material offers an optimized BIL performance while ensuring a leak-proof, compact fit. A jumper wire-top insulator provided on the detachable core allows for convenient installation while offering optimal protection of a circuit from corrosion and animal damages. 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)
