The Dry Type Transformer is mainly used to increase or decrease voltages and currents in an electrical circuit. This type of transformer consists of an iron core which is made of silicon steel and a coil cast by epoxy resin. An insulating cylinder is placed between the high and low voltage coils to increase the electrical insulation. Because the equipment has the advantages of strong short-circuit resistance, high operating efficiency, small volume and low noise, it is often used in a wide variety of places with high performance requirements such as fire prevention and explosion protection. Because dry transformers are much safer, they can be placed indoors, closer to the load, making the whole system more efficient.
