Abstract

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 rigid conductor line, stem insulator used in movable bracket and AC/DC different phase section insulator that localization development is necessary.
