Salt River Project

Salt River Project chose to rejuvenate the least-reliable feeder cable using a hybrid approach of Improved Unsustained Rejuvenation (iUPR) and Sustained Pressure Rejuvenation (SPR) injection processes with Cablecure® 732 injection fluid. This strategy allows SRP to delay replacement of faulty cable while extending the cable life by decades. To date, the utility has rejuvenated nearly 10 million feet or 80 percent of the potential URD cable.

Rejuvenated cable is restored to like-new condition. The Novinium processes are significantly improving SRP’s bottom line. The utility is confident that by including rejuvenation in the asset management plan, they are achieving the highest reliability at the lowest cost for customers. SRP has experienced a rejuvenated cable failure rate of less than 1 percent using the hybrid approach.
