Understanding Cable Rejuvenation: A Modern Approach to Grid Reliability
- •Aging underground polyethylene (PE) and ethylene-propylene rubber (EPR) cables, some over 60 years old, are failing prematurely due to 'water treeing,' threatening grid reliability.
- •Traditional replacement of these cables is described as costly and labor-intensive, creating a significant challenge for grid operators.
- •Cable rejuvenation is presented as a modern, cost-effective solution to extend the lifespan of existing underground infrastructure, thereby enhancing overall grid reliability and stability for developers and large power consumers.
