The contact line pantograph running track range

Positioning means comprises a positioning tube and the retainer. Its purpose is to fix the position of the line of contact, the contact line pantograph running track range, to ensure the contact line and power transformers departing from and the level of the contact line load passed pillar positioner has straight pipe locator , pipe locator. After using the belt speed multifunction vibration damping device locator, circuit breakers pantograph take flow characteristics. Catenary catenary is the role of the contact line through the hanging strings hung up. Catenary can also carry a certain current to reduce the traction network impedance, reducing voltage loss and energy consumption.
