In this thesis, As electric railway vehicle's speed becomes faster and faster and functional, the conditions of operation (or running condition) of the vehicle also become complicated and diverse. As the number of electric vehicle increases by enhancement of the running condition, problems are also raised in circulation current, vibration and unstable contact caused by equipment(sporting part for making horizontal between Trolley wire and Messenger wire) and troubles in Ark by un secure contact. This articles shows a method to prevent or to have least problem of vibration, and unstable contact by having constant height of Trolley wire through adjusting the length of Hanger.
