Product Details
Three phase dry type transformers rely on air convection for cooling, which refers to transformers with iron cores and windings not immersed in insulating oil. They are widely used in CNC mechanical equipment, airports, docks, aging and other places that require voltage conversion.
The three-phase dry type transformer can be suitable for various voltage conversions: three-phase 380V to three-phase 220V, three-phase 380V to three-phase 200V, three-phase 380V to single-phase 220, three-phase 380V to single-phase 200V, three-phase 380V to three-phase 129V, three-phase 380V to 120V, three-phase 380V to 36V, three-phase 380V to 24V, and other voltage conversions.
