High Voltage Cable Terminations

  • Tight Cable Sealing – HV termination retains resiliency and pressure after prolonged aging and outdoor pollution exposure
  • Flexible Cold Shrink – QT-III accommodates all power cable manufacturers bend radius tolerances and recommendations
  • Reliability – high dry and wet insulation resistance for switchgear, transformer or outdoor pole  termination
  • Versatile – QT-III Cold Shrink terminations install quickly and accommodates a wide range of cable sizes
  • Dependable – proven long-term reliability and safe operation at overload temperature on MV HV power system networks
  • Time Efficient – reduced installation time for the Jointer compared to heat shrink, electrical taping or resins
  • Ozone, Heat and UV Resistancethe physical characteristics of silicone rubber Cold Shrink provide excellent performance over the very wide temperature range of -150°F (-100°C) to 600°F (315°C)

Cold Shrink Reliability Record Low Failure Rates*: – 0.067% for Cold Shrink Cable Joints/Splices – 0.022% for Cold Shrink Terminations
