Cable Joints

Nexans GTS1 type MV cable joints are straight heat shrink joints for jointing single core polymeric insulated medium voltage cables with extruded easy strip conductive screen or bonded extruded conductive screen. Nexans GTS1 heat shrink cable joints are fully screened, submersible and can be directly buried into cable trench.

Nexans cable joints are available in both heat shrink and cold shrink technologies for jointing and repairing medium/high voltage cables up to 33kV – single core and 3 core cable joints kits are available for MV-HV cables with paper or polymeric insulation, copper wire or copper screen and armoured/unarmoured construction. The cable joints accommodate both shearbolt cable connectors or crimp connectors.

The installation Cable Jointing Video focuses on  ➡

  • Installation of outer protection heat shrink tube with heat activated adhesive
  • Cable preparation of XLPE PILC cables using cable jointers tools
  • Removal of lead sheath cover from MV-HV cable with paper insulation
  • Removal of paper insulation and heat shrinking of the oil barrier tube
  • Installation and shrinking of the semi-conductive heat shrink tubes
  • Application of stress control mastics to the heat shrink joint
  • Installation of semi-conductive heat shrink 3 core cable breakout
  • Installation of insulating cable breakout
  • Cable stripping measurement prior to installing mechanical shearbolt cable connectors
  • Use of void filling mastics and sealing mastics to insulate the cable joint connectors
  • Installation of dual wall screened tubes to the heat shrink cable joint
  • Earthing of copper wire screens using constant force springs
