Cost-Effective Cable Insulation: Nanoclay Reinforced Ethylene-Propylene-Rubber for Low-Cost HVDC Cabling
GENI Project: GE is developing new, low-cost insulation for high-voltage direct current (HVDC) electricity transmission cables. The current material used to insulate HVDC transmission cables is very expensive and can account for as much as 1/3 of the total cost of a high-voltage transmission system. GE is embedding nanomaterials into specialty rubber to create its insulation. Not only are these materials less expensive than those used in conventional HVDC insulation, but also they will help suppress excess charge accumulation. The excess charge left behind on a cable poses a major challenge for high-voltage insulation—if it’s not kept to a low level, it could ultimately lead the insulation to fail. GE’s low-cost insulation is compatible with existing U.S. cable manufacturing processes, further enhancing its cost effectiveness.
