직류용 FRP제 지지애자 장간애자 시작품 특성 및 개발에 따른 고찰

초록

The domestic train's operator has used DC 1500 V electric railway system's porcelain support insulators in tunnel section and porcelain stem insulators on ground section by overseas imports. The need of development of the polymer insulator (the rest is FRP insulator) has increased because the characteristics of porcelain insulator are very easily breaking and heavy. Nowdays, the FRP (Fiber Reinforced Plastic) stem insulator and feeder line support FRP insulator developed by domestic engineer have been used in AC 25 kV system for about 10 years. We have developed DC 1500 V system FRP insulator derived from reliability and stability of AC 25 kV system and processed authorization prototype test. This paper treats development process and the characteristics of the prototype.
