710435Cable ExtractionClosedGRD Proof of ConceptInnovate UKThe Environment Agency is very concerned when High Voltage Electricity suppliers leave oil filled redundant cables in the ground. This leaves potential for the oil to leak into the ground and have an impact on water courses, flora and fauna and even the local community. Our innovative idea is to extract the copper core and oil impregnated papers of the High Voltage cable left in ground. This eliminates and potential oil leaks. The extracted copper can be recycled and reused for future cable manufacturing and the procedure also leaves a duct in the ground which could help provide a new fibre optic link to the community. Currently HV cable is removed using open trenches for the full length of the cable which is highly costly and disruptive. Our approach involves digging small pits at intervals along the cable, and using our prototype hydraulic test rig to wind out the cable in lengths, extracting the oil, paper and copper as part of the process. Rook wish to carry out a proof of concept project to establish whether the cable can in fact be cleanly extracted using our prototype hydraulic rig, safely, effectively and without any papers left in the pipe.
