Cable Terminations

Nexans OTK are single core cold shrink cable terminations for use indoor and specified to terminate and connect medium/high voltage cables in the following voltage classes:

  • 6/10 (12) kV
  • 6.35/11 (12) kV
  • 8.7/15 (17.5) kV
  • 12/20 (24) kV
  • 12.7/22 (24) kV

Cold Shrinkable terminations require no “hot-working” for safe use in potentially explosive atmospheres and hazardous area locations – the cable terminations are designed for use with polymeric insulated cables (XLPE & EPR). To enable the fault repair, extension, splicing and jointing of existing LV MV HV power cables up to 33kV we also stock a complete range of cold shrink joints.

Euromold ITK - Cable Lugs

All commercialised European standard cable lugs can be used. Cable lugs should be within the dimensions specified (not applicable for Nexans OTK 312 and OTK 324).

Nexans

Thorne & Derrick distribute the complete range of medium/high voltage electrical equipment manufactured by Nexans – this includes Euromold bushings for use with oil fluid or gas insulated switchgear or transformers and associated screened separable connectors according to both IEC (Euromold) and IEEE (Elastimold) for the termination, connect+disconnect of MV-HV cables onto power distribution systems. To protect power systems against high voltage surges resulting from lightning or switching a complete range of surge arresters are available to be used with Euromold connectors in 11kV/12kV, 24kV and 33kV/36kV voltage classes.
