TRACTION DISTRIBUTION

NEW TECHNOLOGICAL DEVELOPMENTS IN ELECTRIC TRACTION

2X25,000 Volts OHE system against 25,000 Volt OHE system on Eastern and Western DFC to reduce number of TSS and increase number of trains in the section.
High rise OHE of 7.5 mts to carry double stack container traffic Western DFC
Tower Car with Measuring & Recording Instruments: for predictive maintenance of OHE.
Mechanized Wiring Train for Railway Electrification

2X25 KV SYSTEM


MAJOR OPERATIONAL ADVANTAGES OF 2x25kV SYSTEM

  • Higher hauling capacity
  • Increased Traction Substation spacing at 60-80 km apart against existing spacing of 40 km.
  • Higher OHE current carrying capacity due to doubling of voltage (50kV).
  • Improved voltage regulation and reduced transmission line losses
  • Seamless running of locomotives from 1×25 kV to 2×25 kV system.


HIGH RISE OHE(7.57 M)




  • Required for double stack container operations with electric traction.
  • Successful trials done in ECoR with OHE height as 7.45 meter Pantograph also suitably modified.
  • Normal OHE height is 5.5 meter. Complete Western DFC is with high rise OHE.
  • On Indian Railway routes, high rise OHE being provided in Gurgaon-Mehsana, Jaipur-Phulera, Rewari-Ludhiana. Total 1188 RKM.


Self-Propelled Wiring Train
For simultaneous stringing of catenary & contact wire. Will increase the pace of electrification






Self Propelled Mast Erection Vehicle





TOWER CAR WITH MEASURING & RECORDING INSTRUMENTATION
(for predictive maintenance)




  • For measurement and recording of vital OHE parameters like contact wire height, stagger, implantation, gradient etc.
  • Likely failure locations identified and timely corrective action taken.
