Overhead rigid suspended current bar profile system
Overhead rigid suspended current bar profile system is a power supply mode for urban rail transit system in which contact cables are clamped inside current bar profile and the locomotive takes current from pantograph on rail top. It is widely used for power supply for tunnels, stations, and passages under bridge. Compared with traditional overhead flexible catenary, it features the following:
1. Stronger current carrying capacity; 2. No risk of power supply interruption, hence safer; 3. Simple operation and maintenance; 4.Effective saving of tunnel space and great reduction of civil works costs.
