Extending the Life of Underground Transmission Lines Through Cable Rejuvenation

Date: December 2

Time: 1:00 – 2:00 pm CST

As the first solid-dielectric transmission cables approach the end of their life estimation, circuit owners are faced with a decision on how best to ensure grid reliability, often weighing the cost, timeline, and impact of replacement against cable rejuvenation. Join us to learn more about cable rejuvenation with the recent application of injection technology toward a critical transmission circuit feeding a major regional employer in the Midwest.


  • Water treeing is a major issue with the early cable that were developed in the 1950s and 1960s and is a major cause of aging cable today
  • Cable replacement is not the only option available to end-users
  • Injection adaptors can be installed in the PAT119 with minimal modifications
