H.V. Bushing Services provides porcelain insulator repair services. Damaged porcelain insulators can be rebuilt and re-coloured as the original, providing a cost-effective alternative to bushing or insulator replacement.

This removes the obvious health and safety concerns associated with sharp broken porcelain particularly during cleaning procedures, sealing the surface against possible moisture ingress and reinstating creepage distances.

H.V. Bushing Services carries out bushing oil sampling, top up and analysis (if required) of all types of oil filled bushings (pressurised, wall / roof or transformer bushings), other site equipment and CTs.

Replacement gauges and pressure switches can be supplied and fitted by H.V. Bushing Services.

Remote pressure gauges, sample points and mounting brackets can be fitted, resulting in an improved visual indication of pressure in comparison to old, small and often inaccurate gauges.

400kV wall bushings can be fitted with floor level gauges and sample points allowing for oil sampling and top up of live circuits.

H.V. Bushing Services carries out the refurbishment of bushings <145kV SRBP and ERIP cored. This service includes oil sampling, strip down, inspection of core, insulator bore and internal connections, cleaning, rebuild with new gaskets and seals, repaint and packaging for dispatch.

H.V. Bushing Services can perform on-site assessment of a bushing's condition, and provide recommendations and a bushing condition assessment report.

H.V. Bushing Services also offers technical support for all types of bushings, particularly B.E.B.S. T2 and functional specification designs, bushing on-site handling, installation and removal.
