We has been developing and manufacturing H class, F class, H class filling type, B class epoxy cast resin dry-type transformer for power distribution since 1994. 

Transformers are categorized into oil-cooled and air-cooled types. Dry-type transformers are air-cooled. Generally speaking, the volume and weight of dry-type transformers are smaller than those of oil-type transformers. And the main function is to convert the voltage to the desired voltage. The transformer has a step-by-step voltage regulation, which means that its voltage value and number of steps have been determined before production. When changing to the required voltage, it is necessary to first cut off the power and change the position of the wires to correspond to the voltage we want. When will we need it? For example, when we purchase equipment from abroad that is 460V, and the factory voltage is supplied on 220V, then we will need a transformer to help us boost the 220V to 460V to correspond to the equipment we purchased.
