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.
Provides a void-free seal to jacketed concentric neutral and concentric neutral power cables
High dielectric-constant material regulates the distribution of electric field stress
Suitable for outdoor applications
Termination has 0.64 to 1.08-in insulation O.D., 0.97 to 1.48-in jacket O.D. and 0.22 to 1.31-in connector/drop wire O.D.
Accommodates wire sizes of 4/0 AWG to 400 kcmil at 5kV, 3/0 AWG to 300 kcmil at 8 kV, 2 to 4/0 AWG at 15kV, 2 to 1/0 AWG at 25/28 kV
Integrated, jumper wire-top insulator and step-core design allows for easier installation, while sealing compounds provide constant radial pressure
Withstands voltages of 5 to 25/28 kV and is 150 kV BIL-rated
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.
