Understanding Cable Rejuvenation: A Modern Approach to Grid Reliability
For more than 60 years, polyethylene (PE) and ethylene-propylene rubber (EPR) underground cables have powered communities, industries, and progress. The hope was these cables could last decades before needing to be replaced, but due to water treeing—microscopic moisture-induced formations that degrade insulation and threaten reliability, they’re aging more rapidly than expected. With traditional replacement being costly and labor-intensive, it was time for a new solution.
