Reducing Failure Rates of Underground Cable Networks

When maintained in good condition, underground cable distribution systems provide exceptionally high security of supply compared with overhead line systems, due to a low incident of failure from external causes such as severe weather or external accident. 

However, underground cables are subject to deterioration from a range of root-causes, and without dedicated asset management, the systems will inevitably under perform.
