JDZ(J)-3、6、10Q Voltage Transformer

The JDZ(J)-3、6、10Q is a series of indoor voltage transformers designed for 3kV, 6kV, and 10kV medium-voltage power systems. Available in both JDZ (single-phase, two-winding) and JDZJ (single-phase, three-winding) configurations, these transformers deliver reliable voltage measurement and protection signal conversion for switchgear, metering cabinets, and distribution panels, making them ideal for utility substations, industrial facilities, and commercial power installations.
