초록

Objective of the study is development of 23kV insulating jackets for protection of workers from electrical shock. The breakdown voltage of Ethylene-VinylAcetate copolymers(EVA) films in insulating oil were measured. Insulating jackets were made by the high frequency welding machine, and withstanding voltage test of these were measured. For breakdown voltage at AC 30kV, the number of EVA film with $105{\pm}5{\mu}m$ thickness was 4$\sim$5pieces. When AC 30kV during 3 minutes supplied on the insulating jackets, those were keep on the good quality.
