Triplex Cable Joints & Terminations Overview 

  • SPS 11kV Triplex Straight Cable Joints & Terminations (Indoor & Outdoor)
  • SPS 11kV Triplex Polymeric Trifurcating Cable Joints for 11kV high voltage cable jointing of 11kV XLPE/CTS SWA 3 core (BS6622) to 11kV Triplex (BS7870)
  • SPS 11kV Triplex Transition Trifurcating Cable Joints for 11kV high voltage cable jointing of 11kV PILC/SWA 3 core to 11kV Triplex (BS7870)

11kV Triplex heat shrink cable terminations and cable joints are tested and qualified to InternationalCable Terminations Standards including Cenelec Standard (HD 628 S1 and 629.1 S2:2006), encompassing VDE0278 and IEC60502.

Triplex Cable Termination 11kV - Bonding & Earthing 
High voltage 11kV Triplex copper earth screen wires must be bonded together and connected to the substation HV earth - copper wires of each single core should be gathered together into a single brass shear bolt lug or copper crimp lug. Most cable gland plates incorporate a parking bar suitable for bolting the three cable lugs onto - a further connection is required from this parking bar to the substation HV earth.
