Disconnector Panel

Disconnector Panel

Incoming disconnector cubicles isolate the high-voltage output of the rectifier groups from the DC feeder distribution bus. Negative disconnector cubicles isolate the rectifier negative pole and can contain one or multiple single-pole disconnectors. Coupling disconnector cubicles split the main busbar into separate sections.

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