직류용 FRP 폴리머 장간애자의 전기적 특성에 관한 연구

Fiber Reinforced Plastic (FRP) insulators for direct current (DC) were developed and their electrical characteristics were investigated. Electrical tests were carried out to measure withstanding and flashover voltages under common use frequency condition. Tensile and bending tests were performed for the mechanical characteristics. The test results showed that DC FRP insulators had superior voltage resistances and strengths to porcelain insulators.
