Copper Jumper

Looking for any other voltage system, means everything has got to be developed namely traction Power Supply System, Over Head Equipment, Vehicle Traction System etc. In order to increase OHE voltage, 2×25 kV system is developed so that at vehicle level, the voltage remains 25 kV. Some Railways have preferred for 50 kV system but the same is limited to heavy haul dedicated rail system in which the locomotive also remains confined in that territory only. There are not many suppliers of this traction system. Dedicated freight Corridor project in India is meant for heavy haul, but the locomotive has to work in DFC and IR territory, therefore, 2x25kV power supply system is chosen.
