Rectifier Panel

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.
