6/12kV heat shrinkable joints
 

Heat shrinkable medium voltage branch joints for XLPE and paper insulated cables up to 15 kV

Features:

  • Unique stress control system: High permittivity material
  • Compact design, Few components
  • Simple to install, Minimal waste for disposal
    • Fast, consistent installation means lower installed costs
    • No special installation tools or dies needed
    • Installation environment: use of torch adds flexibility to cable preparation in any climate
  • High reliability
  • Heat-activated seals ensure maximum protection against moisture ingress
  • Lightweight construction requires no additional support
  • Tough abrasion-resistant outer covering protects against damage from improper backfill
  • Mechanical robustness
  • Meet: GB/T 12706 Standard

Heat shrinkable joint for XLPE Single Core Cable up to 15kV
  1. Semi Conductive Tape
  2. Stress Control Tubing: Heat- shrinkable tubing with a precisely defined impedance characteristic smoothes the electrical field over the connector and screen ends.
  3. Insulation Tubing: High voltage insulating tubings restore the conductor insulation. The elastic memory of the heat shrinkable components ensures the correct wall thickness is obtained.
  4. Screened Insulation Tubing: Enables the final insulating layer (red) to be installed complete with a conductive polymeric screen (black).
