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
- Fault location jointing support — following TDR pre-location and acoustic pinpointing
- Out-of-hours and emergency response — available by agreement
- Post-repair testing support — sheath testing and pre-energisation inspection
- Re-energisation support — present on site through circuit restoration
Working with Fault Location Teams
We work closely with cable fault location specialists, coordinating the repair mobilisation once the fault position has been confirmed. If you need both fault location and repair under one contractor, our sister service at CableFaultLocation.co.uk provides specialist HV and LV fault location services — with R&D Cable Jointing available to carry out the repair on the same mobilisation where possible.
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
Need cable fault location first? Our specialist fault location service is available at CableFaultLocation.co.uk — HV and LV fault finding, sheath fault location, cable route tracing and cable identification across the UK.
