33. SALIENT FEATURES OF OHE SYSTEM Flexible current carrying droppers . The droppers used as standard application are current carrying type to shorten the distances between points for equipotential bonding and allowing a better current conduction between contact wire and messenger wire. Advantages: Fit and forget type Reduced risk of breakage Reduced maintenance Better current collection Less weight, thereby less influence on dynamic behaviour Higher system height providing more flexibility Less material costs Free from wear Wide range of providers and Standardized fixing material . Droppers:- 1/22/2022

34. SALIENT FEATURES OF OHE SYSTEM Light Weight Section Insulator:-   The lightweight section insulators are designed for separating overhead contact line systems into individual switch and feeder sections. Universally applicable for different contact wire types. Easy installation due to low weight and simple geometric design High service life due to very good arc extinguishing capability Low life cycle costs due to use of corrosion resistant materials Optimum running behaviour of pantograph due to effective adjusting device 1/22/2022
