Find the fault. Fix the cable. Restore the supply.
Lost supply on a buried cable? We test, pre-locate and pinpoint LV and 11kV cable faults, then repair them with our own jointing team at R&D Cable Jointing. One call from fault to restored supply.
Phones answered Mon–Fri, 8am–4pm. Out-of-hours by arrangement.
Straightforward LV faults are often located with insulation tests and a TDR. A high-resistance 11kV fault can need a surge generator and an acoustic pinpointer, which we hire for that job when you have agreed.

View service →Cable Fault Location is a trading name of R&D Cable Jointing Ltd. When the fault position is known and the cable is safe to work on, the repair is done by R&D’s own jointers.
Jointing up to 33kV is part of R&D’s own work, where the job is suitable. Fault location on a difficult high-resistance cable can still need a hired surge generator and acoustic pinpointer. We agree that before proceeding.
We ask for the useful facts first, so the visit brings the right instruments.
Voltage, cable type, approximate length, what tripped, and any test results you already have.
Open circuit, short, earth fault, low resistance, or a fault that only breaks down at higher voltage.
TDR with our own instrument, or a hired surge method if the fault needs it.
Trace the route and narrow the position before anyone digs.
Our own jointers repair the cable once it is isolated and accessible.
These are the instruments we own. A surge generator and acoustic pinpointer are hired for the faults that need them.
We hire these for the job only when they are needed, and only when that hire has been agreed.
Send the voltage, the postcode and what you know so far. We’ll call you back during phone hours.
