250KVA 3 phase autotransformer

250KVA 3 phase autotransformer

250KVA 3 phase autotransformer is a dry-type transformer which is mainly used for step-down, suitable for various large equipment

This 250KVA 3 phase autotransformer is constructed of high-quality copper or aluminum wire to step down the input voltage to a usable range output.

250KVA transformers are sold at manufacturer prices, which is a benefit of choosing to buy transformers from a transformer factory.

250KVA 3 phase autotransformer is manufactured and supplied by Shuogong Power, a leading transformer company in China.

Its standard input voltage is 380V, output voltage is 220V/200V, frequency is 50/60Hz, and copper/aluminum wire is optional.

Dry-type autotransformer, electromagnetic induction, primary and secondary windings are insulated separately.

In addition to standard input and output voltages, we can also customize dry type transformers that meet your needs. Whatever voltage you need, our strong R&D team can support you. This is our advantage.
