Details
  • Provides a void-free seal to tape shield, wire shield and UniShield® power cables
  • High dielectric-constant material regulates the distribution of electric field stress
  • Suitable for outdoor applications
  • Integrated design allows for easier installation in limited spaces, while sealing compounds provide constant radial pressure

3M™ Cold Shrink QT III 7620 S & 7690 S Series Inverted Termination Kit includes 3 single conductor, skirted terminations. It ensures a pliable, tight seal for tape shield, wire shield and UniShield® power cables. The conjunction of high dielectric constant material and sealing compounds allows the termination to withstand voltages of 5 to 35kV.
