Southwire Cable Rejuvenation Services: Extend the Life of Underground Cable

August 28, 2025

Southwire’s Cable Rejuvenation Services brings new life to your existing underground cables. Southwire’s highly experienced service teams inject damaged segments with a silicone-based fluid that reacts with the chemistry of the insulation to revitalize cable strength and extend life expectancy.

Southwire’s services teams are dedicated to providing technical and operational support, prioritizing safety, efficiency, and cost-effectiveness for all our clients. Over the course of more than 30 years, Southwire has rejuvenated over 150 million feet of underground cable, with a 99% success rate, saving our clients tens of billions of dollars, and improving electrical grid reliability for millions of customers.
