Study on Improvements to the Dielectric Breakdown Strength of Extruded Dielectric Cables

IEEE Transactions on Power Apparatus and Systems, 1985
This report relates to the study on insulation materials for obtaining extruded dielectric cables with high dielectric breakdown strength. Firstly, the dielectric breakdown strength (EB) of a variety of plastics was evaluated by the use of recessed sheet samples. As a result, the EB for high density polyethylene (HDPE) proved favorable.
