New EHV cable research laboratory: Features unique cyclic-load test equipment

FROM 1945 TO 1958, the noncoincident peak load in the United States increased from 40- to 118-million kw, tripling in 13 years. Future load growth at anywhere near this rate will require higher voltage transmission. Difficulty of obtaining right-of-way for additional and higher voltage overhead lines will increase demand for extra-high-voltage (EHV) insulated cable; capable of transmitting 500 mva and over at 230 kv and higher.
