Underground Cable Installation and Maintenance

Underground cables keep power flowing safely where overhead lines are not practical. Adoforce Electrical Contractors installs, joints, tests and maintains low, medium and high voltage cable networks up to 132kV for municipalities, utilities, developers and industrial sites.

Our underground cable services

Fast, accurate cable fault finding

A cable fault can shut down a neighbourhood, a factory or a hospital. Our technicians use specialised test equipment to trace cable routes and pinpoint faults accurately, which means less digging, shorter outages and lower repair costs. We then repair, test and re-energise the cable so supply is restored safely.
