Highlights
  • 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
  • Integrated step-core design allows for easier installation, while sealing compounds provide constant radial pressure

3M™ Cold Shrink QT III 7640 S INV & 7650 S INV Series Inverted Termination Kit includes a single conductor, skirted termination. 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 35kV.
