Air-Insulated Ring Main Units

Air-insulated medium-voltage ring main units are designed for secondary distribution, switching, protection and control applications in utility, industrial and infrastructure power systems.

TOONICE provides XGN15 and XGN66 series air-insulated ring main units for different feeder arrangements and project requirements, using air as the primary insulation medium with vacuum and SF₆ switching technologies according to configuration.

Project-based configurations are available according to system voltage, rated current, short-circuit level, feeder arrangement, protection scheme, metering requirements and installation conditions.
