Three-phase Autotransformer

G series three-phase dry type transformerare specifically designed to set up or down the network voltage in order to supply the needed voltage equipment intened to be associated. Our company has adopted the high-quality and advanced technology to specialize in three-phase voltage transformers of series for many years. We uses imported cold-rolled silicon steel stack loading and high temperature insulation composite material. Through the coil effectively reduces the temperature. It uses special dipping resin with high permeability and low loss, low noise, low temperature, radiation resistance,maintenance-free, high environmental protection and so on. All products can be customized according to customer requirements. Application: Various advanced welding equipment and other industrial, commercial electricity facilities where special voltage is needed.
