Fiber Reinforced Plastic (FRP) insulator has a higher performance than porcelain. It is only used in domestic AC 25 ㎸ electric railway system. Seoul Metro has developed DC 1500 V polymer stem insulator since 2008. The test of electrical, chemical, mechanical tests are carried out. The test results revealed that all result values satisfy the test standard.

Fiber Reinforced Plastic (FRP) insulator has a higher performance than porcelain. It is only used in domestic AC 25 ㎸ 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.

The use of polymer insulator has increased all over the world. As of 2000's KEPCO has used it fully since they introduced it in early 1990's. In Korea it is very widely used by KORAIL which uses AC 25 kV system in the ground electric car line. And It is also used in tunnel electric car line to support AT feeder line. But it has not been used in the section of DC 1500 V. In case of DC 1500 V electric railway system It is has been developed by research institutes by means of R&D projects since 2008. The user cleans porcelain insulators regularly by water because of dusts and pollution. In case of polymer insulators It is very easy to be made dirty by pollution because of the material properties and hard to be cleaned by cleansing. In accordance with these reasons It is worried about deterioration. This paper deals with anticipating problems when we apply it to DC electric railway system and the procedure for testing polymer support insulator.

The Seoul subway is acting the center of public transportation after the opening of the first line on August 15, 1974. and the subway line of the DC traction system is running and building to the ninth line. However, the main insulation parts used in overhead contact line are now imported from overseas products. Therefore, this paper considers domestic manufacture technology, supply easiness and economic effectiveness of insulation products and reviews the safety of support insulator used in r igid c onductor l ine, s tem insulator used in m ovable b racket a nd A C /DC different p hase section insulator that localization development is necessary
