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.
Claims11
An insulated high voltage cable comprising a conductor insulated with at least two laminar layers of insulating material, at least one of said layers being relatively thick and having a low SIC of no greater than 4.5, at least one other of said layers having a high SIC of 7 or more and being in contact and interfacing with a surface of said low SIC layer, said high SIC layer being relatively thin and having a tan .delta./SIC value no greater than 0.005 over a temperature range of 40.degree. to 90.degree. C.
