Abstract :
When the need for extra-high-voltage cables for handling large amounts of power became apparent, a research program was undertaken at the Okonite Company to develop and build an experimental 230-kv cable. Two 500-foot pilot lengths were made, each having a different type of insulation, and a series of exhaustive tests proved the manufacturing procedure excellent. Because of these tests and other successful cables the Okonite engineers had designed, the company was awarded the contract for a 230-kv Oilostatic cable by the Canadian-Brazilian Services, Ltd., of Toronto, Ont., Canada, for installation in the Cubatao Underground Power Plant of the Sao Paulo Light and Power Company, Ltd., Sao Paulo, Brazil.
