HV Cable Fault Repair: 11kV & 33kV

R&D Cable Jointing provides HV fault response support for 11kV and 33kV networks. We assist with fault repairs once locations have been identified and access is available. Based in Kent and operating nationwide, we regularly support urgent works across Essex, London, Kent, Hertfordshire, Surrey, Suffolk, Cambridgeshire and Bedfordshire.

HV Fault Repair Services

Fault response work is about speed, control and coordination. We integrate with your site team to carry out repairs safely and return circuits to service as efficiently as possible.

  • Failed joint replacement: 11kV and 33kV straight joints, any cable type
  • Cable section replacement: where the fault has damaged a length of cable
  • Jointing support once the fault position is confirmed, ready for immediate excavation and repair
  • Post-repair testing support: sheath testing and pre-energisation inspection
  • Re-energisation support: present on site through circuit restoration

What We Need Before Mobilising

To respond effectively to an HV fault repair requirement, we need:

  • Fault location confirmed: position on cable route established by fault location team
  • Site access arranged: excavation access, permit-to-work arrangements confirmed
  • Cable details: cable type and voltage confirmed, joint kit specified or agreed
  • Safety management framework: SAP in place, isolation confirmed before our engineers enter the excavation
