  • Insulated high voltage cables
    Patent number: 4361723
    Abstract: There is provided an insulated high voltage cable which possesses the property of lower dielectric losses than prior art cables. The cable comprises a conductor insulated with at least two laminar layers of insulating material. At least one of the layers is relatively thick and has a low SIC. At least one other of the layers has a high SIC and is in contact with a surface of the low SIC layer. The high SIC layer is relatively thin and has a tan .delta./SIC value no greater than 0.005 over a temperature range of 40.degree. to 90.degree. C.
