11kV Termination - Single Core XLPE EPR Heat Shrink Cable Terminations

Cable Terminations 11kV 33kV | Single & 3 Core | Medium & High Voltage Cables MV HV

Nexans cable terminations are suitable for connecting and terminating 33kV single core polymeric cables with stranded copper or aluminium conductors, 16-800sqmm.

33kV terminations connect medium/high voltage power cables with polymeric insulation including XLPE and EPR to MV-HV switchgear, transformers and cable boxes – suits single core bonded or easy strip semi-conductive screens.

MV-HV cables distributing 33kV power should always be prepared using correct cable jointing tools.

33kV cable terminations suit both copper tape screened (CTS) and copper wire screened (CWS), armoured (steel wire/braid) or unarmoured cables – single core heat shrink cable terminations are supplied in sets of 3 phases with sufficient materials to effectively terminate 3 single core cable ends.

33kV terminations are tested to international standards including CENELEC HD629.1 and IEC60502-4.

Installing HV Heat Shrink Cable Terminations 33kV
  • 33kV Cables With Copper Wire Screen or Copper Tape Screens
Copper Wire Screen Cables
  1. Remove the outer cable sheath with 33kV sheath stripping pliers over a distance L + X (L= see table below, X = depth of cable lug barrel + 5mm). Remove bedding tape and copper strip. Clean the outer cable sheath over a distance of 50mm and apply a layer of red thermoplastic tape (with a 50% overlap).
  2. Bend back the copper wire screens over the cable sheath in a parallel way so that each wire rests upon the thermoplastic tape. Fix with a wire wrapping (2 or 3 windings) at about 50mm below the cutback edge of the 33kV cable sheath. Twist and bind the copper wire screens together, cut at the correct length, install the 33kV cable lugs and connect to earth. For cable terminations located outdoors with armour (SWA or AWA) also connect the earth braid/wire screen to the 33kV cable armour by soldering or solderless earth connection.
  3. The 33kV cable jointer should then remove the conductive tapes and elements for longitudinal water tightness.
Copper Tape Screen Cables
  • Remove the outer cable sheath with sheath stripping pliers over a distance L + X (L= see table below, X = depth of cable lug barrel + 5mm). Remove bedding tape. Clean the outer cable sheath over a distance of 50mm and apply a layer of red thermoplastic tape (with a 50% overlap). Carefully remove the 33kV copper tape screen over a distance up to 20mm from the outer sheath.
  • Connect the earth braid to the copper tape screen, by using a copper wire binder and soldering or by a constant force spring. For 33kV cables with armour (SWA or AWA) also connect the earth braid to the cable armour by soldering or other equivalent method. Apply solder to the braid to form a moisture block at about 10mm below the cable sheath edge. Attach the braid with a wire wrapping at 50mm below the outer cut back edge.
  • The high voltage cable jointer should then remove the conductive tapes and elements for longitudinal water tightness.
