Nowaday,as the important component parts of kinds of electric appliances and power supply ,both of isolation transformers and autotransformers are widely used. Unlike an isolation transformer which has physical separation from the primary and secondary windings in order to allow magnetic coupling between isolated circuits ,autotransformer use common windings and offer no interference or disturbance isolation. The another distinctions of isolation transformers and autotransformers are that autotransformer enjoys more advantages such as larger capacity ,higher efficiency, smaller size and lower cost.

Dibao's large-power autotransformer:
Our factory have been the manufacturer designing and supplying the dry-type autotransformers for more than 10 years. Not only the small-size and middle-size autotransformer can be excellently manufactured by us with ease, but also various large-powers autotransformers which are needed higher manufacture technique can be made. Dibao's engineers exerted much effort in designing the winding equipment to improve the arrangement wire winding and enlarge the size and amount of copper wire when winding a product. At present, six pieces and as much as 2.5mm diameter copper wire can be winded in one time using our winding equipments which are also designed and made by ourselves. Moreover, the capacity of large autotransformer enable nearly 1000A to pass. The diameter of autotransformer which belongs to truly colossal transformer can reach one meter.
