DEVELOPMENT OF HIGH-REACH PANTOGRAPHS FOR HIGH-SPEED RAILWAYS [PDF]

, 2023
The pantograph’s purpose is to transfer electrical power from the overhead contact line to the train’s electric propulsion unit. To perform its function adequately, it is necessary to maintain the static contact force between the pantograph and the contact line within the values prescribed by appropriate standards for the entire extension range of the ...
