Services
High Voltage Cable Jointing
We provide cable jointing services for networks up to 400kV, working with XLPE, PILC, EPR, and fluid-filled cables. Our teams deliver bespoke end box modifications and retrofits for oil-immersed insulators. With 3M QECC accreditation, we ensure 20-year warranties on joints up to 72kV.
Transformer Maintenance
Our maintenance includes oil sampling, degasification, and fault diagnosis for transformers. We perform monthly and annual checks covering temperature monitoring, silica gel breather maintenance, and leak repairs to extend equipment lifespan and optimise performance.
Cable Fault Location
Using advanced test equipment, we locate faults in private and DNO networks. Our services include TDR testing, VLF diagnostics, and cross-talk analysis, followed by safe isolation, repair, and commissioning with full documentation.
Fibre Optic Installation
We install and joint fibre optic cables alongside HV systems for operational monitoring. Our solutions include retrofitting existing networks with modern data infrastructure to support smart grid technologies and real-time performance tracking.
Degasification Services
Specialist degasification of transformers and fluid-filled cables prevents equipment failure. We perform low oil pressure checks, PCB sampling, and nitrogen-based cable decommissioning to restore baseline performance and safety standards.
