EPIC™ HPFF Retrofit Solution

HPFF cable systems are historically rugged and reliable, which has made them a cornerstone of the transmission grid. However, as these systems age and are damaged, fluid leaks become an environmental concern for citizens and utilities alike. Southwire offers a retrofit solution that uses existing pipe infrastructure and eliminates the need for pressurized fluid. No fluid, no leaks, lower maintenance costs… It’s EPIC!
