Abstract
In the nation, 154kV XLPE cable with an insulation thickness of 23mm have been used for transmission lines. The thickness is designed by old parameters which were determined by Kreuger, Oudin et al. in 1960s. By the way, the manufacturing technology has been developed. Especially in extruding and curing process we are using a triple common extruding head and applying gas-curing process. It allows the quality of XLPE cable improved. The paper evaluates the AC minimum insulation breakdown strength of XLPE power cable using model table. We can verify the uplifted insulation quality. And we expects the cable insulation thickness to be reduced applying the new parameter to the cable insulation design.
