Details
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.
