AC-AC Rail Feeder Autotransformers

Hitachi Energy's AC-AC Rail Feeder Autotransformers are typical single-phase auto-connected transformers. They are mainly used in modern high-power railway catenary systems fed with two phases, generally applied to all rail systems feeding high-speed trains, and more useful where the distance between catenary feeder substations is long. Our AC-AC Rail Feeder Autotransformers are both available in Liquid-filled Transformers and Dry-type Transformers.

 

Key Features

Liquid-filled Transformers Dry-type Transformers
  • Power: from 4 MVA to 15 MVA
  • Voltage: up to 220 kV
  • High efficiency and lower loss due to higher voltage
  • Reduced interference with communication systems thanks to a better collection of returning stray currents
  • Power: Typically up to 10 MVA or 16 MVA
  • Voltage: Typically 2x25 kV, with 52 kV class or 72.5 kV class
  • High efficiency and lower loss due to higher voltage
  • Reduced interference with communication systems because of a better collection of returning stray currents

 

Applications

Liquid-filled Transformers Dry-type Transformers
  • Typical single-phase auto-connected transformers
  • Modern high-power catenary systems fed with two-phase
  • Applied to all rail systems feeding high-speed trains
  • Typical single-phase auto-connected transformers
  • The main goal is to maintain the line voltage between the main traction substations in the HSL (High-Speed Lines)
  • Modern high-power catenary systems fed with two-phase
  • Applied to all rail systems feeding high-speed trains
