Railway Overhead Electrification (OHE) is a system used to supply electrical energy to trains through overhead wires, enabling them to operate efficiently and sustainably. It consists of a network of contact and catenary wires, supported by masts or portals, that transmit high-voltage electricity to the train's pantograph, which collects the power. OHE is widely adopted in modern railways for its ability to support high-speed, long-distance, and heavy freight operations. Key components of the system include insulators for electrical safety, tensioning devices to maintain wire stability, and substations that distribute electricity from the grid. This system offers several advantages, such as reduced reliance on fossil fuels.
