FIELD: electricity.
SUBSTANCE: system of power supply includes the rod (4) of power distribution hingedly installed on a support (5). The said rod is electrically connected with a power source and has a collector shoe (17) for electric contact with the current conducting rail (2) installed on the vehicle. The secondary device for optimal electric contact between the collector shoe (17) and current conducting rail (2) creates a part of the rod (4) and contains an element for temporary contact and support. The track (20) passes over at least a part of the top front section of the vehicle (1) adjacent to the current conducting rail (2). The temporary contact element and support rests against and moves over the track (20) at the initial period of the vehicle (1) passage under the rod (4) till the contact of the collector shoe (17) and the current conducting rail (2).
EFFECT: prevention or mitigation of impacts upon the electric connection making between the vehicle and power distribution rod.
