This project will provide an on-site service which will give the asset owner of all oil filled cables the option of purifying and re using any oil extract from cables during maintenance and repairs. Thus removing the need to dispose of large quantities of waste oil. The chances of this proposed are high - The flushing of an existing circuit has illustrated that it is perfectly plausible to re-generate oil, although we do not believe this has been trialled successfully yet.

Since the first introduction of oil filled cables, manufactures have always insisted that all cable oil removed from oil filled cable, both new and old was discarded to waste. Due to pressures from environmental legislation, the waste oil is normally sent for recycling into other products or disposed at a high cost. This project proposes the following method: Review current best practices in oil regeneration from other asset areas (internal review)Approach supplier for development of an oil regeneration system Development of specific critical components Delivery of cable oil regeneration plant Trials and testingNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
