Details
  • 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 1.53 to 2.32-in insulation O.D., 1.84 to 2.80-in jacket O.D. and 0.60 to 2.80-in connector/drop wire O.D.
  • Accommodates wire sizes of 1750 to 2000 kcmil at 5kV, 1500 to 2000 kcmil at 8 kV, 1250 to 2000 kcmil at 15kV, 900 to 1750 kcmil at 25/28 kV
  • Integrated jumper wire-top insulator and step-core design allow for easier installation, while sealing compounds provide constant radial pressure
  • Withstands voltages of 5 to 25/28 kV and is 150 kV BIL-rated
  • Includes a 4-skirt, cold shrink termination

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.
