Electric Properties of XLPE Model Cables under AC and DC Field at Various Temperatures

none5Two types of model cables having different cross-linked polyethylene (XLPE) materials are investigated in this paper. One material is a standard XLPE homopolymer; the other is high productivity XLPE compound. Electric properties of these cables were studied and compared under AC and DC field, respectively. In particular, AC voltage endurance was evaluated by means of an experimental system developed for ageing and life tests in dry condition. Additional information on the charge trapping phenomenology under DC field was obtained from the space charge measurements.noneL. Wang; D. Fabiani; G. C. Montanari; F. Palmieri; U.H. NilssonL.
