Services
Cable Fault Location
Our cable fault location service identifies and pinpoints HV/LV cable faults using advanced pulse echo and impulse current techniques. We address earth faults, intermittent faults, and sheath damage to restore network integrity swiftly. Available nationwide with rapid response times, ensuring minimal downtime for critical infrastructure.
PD & TD Testing
Partial discharge (PD) and tan delta (TD) testing detect insulation weaknesses in HV cables. Using VLF power supplies, we assess cable health to prevent failures. This service supports maintenance planning and ensures reliability for underground and subsea cable systems up to 400kV.
Cable Jointing
We provide high-voltage cable jointing for LV to 66kV networks, including offshore wind and solar farms. Our GWO-trained engineers use cold shrink, heat shrink, and cold-applied methods from leading manufacturers. This ensures secure, long-lasting connections for private and industrial networks.
OTDR Testing
Optical time-domain reflectometry (OTDR) testing evaluates fibre optic networks for breaks, loss, and reflectance. Using Anritsu and Fluke equipment, we deliver detailed reports for enterprise and data centre clients, ensuring optimal performance of multicore and subsea fibre systems.
VLF & DAC Testing
Very low frequency (VLF) and damped AC (DAC) testing assess cable integrity for commissioning and maintenance. Our HVA systems perform dielectric testing up to 300kV, offering non-destructive diagnostics for transmission lines, wind farms, and industrial installations.
