What is the voltage range carried by a pantograph?

The voltage range carried by a pantograph is typically found within the range of 12,000 to 25,000 volts alternating current (AC). This range is standard for many high-speed trains and electric railway systems, where the pantograph serves as the mechanism that collects electrical energy from overhead wires. The use of AC voltage allows for efficient transmission of power over long distances, which is crucial for railway operations.

In the context of rail systems, the higher voltage levels are necessary to reduce current flow and minimize losses due to resistance in the overhead lines. Such configurations enable electric trains to function effectively, delivering the necessary power for propulsion while maintaining operational efficiency. The correct option supports the knowledge of standard voltages used in modern rail systems, which is essential for safety and operational practices among vehicle rescue technicians.
