A Basic Study of Catenary System Corresponding to Speed-Up of the Rail Way

전기철도 고속화에 대응한 가선구조에 대한 기초연구

Dopper should performance not only to constrain rolling and yawing system but also to develop capability of pantograph. In orde to get purpose, the survey and study that the type of dropper which convert 'I' type dropper into 'Y' type that performance to constrain rolling,yawing and jamping of catenary system simultaneously.
