초록

Fiber Reinforced Plastic (FRP) insulator has a higher performance than porcelain. It is only used in domestic AC 25 kV electric railway system. Seoul Metro has developed DC 1500 V FRP insulator since 2008. FRP support insulator of flexible property is affected by the wind in tunnel. A wind tunnel test was carried out to measure influence on the insulator housing when the train passed by. The test results showed that the wind which is resulted from the passing train had a little impact on the FRP insulator shed movements.
