Rectifier Panel

Rectifier cubicles convert AC voltage from DC transformer to supply the rail network. Air-cooled rectifiers are equipped with high-overload, high-blocking-voltage diodes, or thyristors. These semiconductor devices are time-tested and optimally dimensioned to deliver high performance and reliability.

All disconnector cubicles are indoor configurable solutions based on our 50-yearlong technical experience.

  • DC rated voltage 750V, 1500V and 3000V
  • Power up to 9MW
  • Easy and limited maintenance
  • Reliability and long lifetime
  • Modularity and compactness
  • Compliant to IEC 60146-1-1, IEC 60747, and EN 50328
