Cable Oil Removal Service

for redundant fluid-filled cables

Most of the Electricity Network Operators in the UK have substantial amounts of fluid-filled high voltage underground cables, operating at voltages from 33kV to 400kV. A major problem with fluid-filed cable systems is oil leaks due to ageing or third party damage. Many redundant kilometres of these cable types remain underground, and the oil within these cables continue to pose a threat to the environment.
