도시철도 직류용 FRP 지지애자 및 장간애자 특성 분석

Direct Current Fiber Reinforced Plastic (DC FRP) insulators were developed and their mechanical and 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.
