THE PROBLEM
Water Trees Grow. Insulation Weakens.
Soon after underground cables are installed, the wet environment causes water trees to grow. The growth of water trees reduces the dielectric strength of the insulation. The reduction of this dielectric strength can cause electrical/catastrophic failure of the cable.
Faced with this serious and growing problem in the 1980s, the prospect of addressing this problem on an industry-wide scale through cable replacement only would have been unsustainable, costing tens of billions of dollars and entailing a time frame that could not keep up with the increasing failure rate.
THE SOLUTION
Improve the chemistry of the insulation, and physics of the cable.
Cable injection introduces silicone fluid into power cable strands. The fluid migrates into the conductor shield & insulation. This process improves the chemistry of the insulation and the physics of the cable to extend the reliable life of the circuit.
Since the utility industry began implementation of cable injection programs in 1986, Novinium has rejuvenated over 150 million feet of aging UG cable, saving tens of billions of dollars, and helping utilities in across the U.S. and Canada boost the reliability of the UG power grid.
HOW CABLE REJUVENATION WORKS
Specialized connectors allow silicone fluid to be injected into the power cable strands. The fluid migrates into the conductor shield & insulation, increasing the AC breakdown strength of the insulation and preventing future water tree growth.
The time-released nature of the injection process allows long-term delivery of the functional materials so that rejuvenation not only reverses the failure trend of installed cable, but outperforms cable replacement in the long-term.
“The reliability of rejuvenated cable is the same as replaced cable. Cable rejuvenation is a major part of our URD asset management plan.”
— Manager of Engineering, Leading Colorado Cooperative Utility
