3M Cold Shrink 7600 QT-III Cable Terminations

Technical Specification 

  • Electrical Ratings - 90 degrees Celsius continuous operating temperature, 130 degrees Celsius emergency overload (Class 1 designated to IEEE-48)
  • Hydrophobicity - airborne contaminants deposited on cable termination surfaces can cause destructive leakage currents and discharge-initiated material erosion leading to high voltage tracking, flashover and cable failure. Hydrophobic silicone rubber and EPDM compounds provide 3M Cold Shrink Terminations with a long service life under rain, fog and drizzle weather conditions
  • Oxidation - silicone Cold Shrink resists ozone, corona and weathering
  • Impulse Flashover - 3M QT-III cable terminations exceed IEEE Standard 48-1996 BIL by 50%
  • Industrial Contamination - 3M cable terminations subject to intense and extreme chamber testing to determine tracking performance
  • Dielectric Test - 3M QT111 Cold Shrink terminations conform to IEEE-48, CENELEC HD629.1 S1 and VDE 0278. 7 Pressure Leak Tests - excellent moisture sealed high voltage termination in accordance with IEEE-48 1996
