Which current collector use for higher speed?
Cable
Pole
Bow
Panto-graph
Panto-graph
Panto-graph is the correct answer as it is a current collector used for higher speed electric locomotives. It is designed to collect electrical current from overhead wires while allowing for high-speed movement. This makes it an essential component of electric traction systems.
Panto-graph is the correct answer as it is a current collector used for higher speed electric locomotives. It is designed to collect electrical current from overhead wires while allowing for high-speed movement. This makes it an essential component of electric traction systems.
The panto-graph works by using sprung arms that press against the underside of the overhead wire, allowing for the collection of electrical current. As the locomotive moves, the panto-graph adjusts its position to maintain contact with the wire, ensuring a continuous flow of electricity. The design enables it to operate effectively at higher speeds by minimizing the impact of movement on the contact.
