Self-Coupling Transformer QZB Series For Motor Starting

June 15, 2024

Description:

We can supply Self-Coupling Transformer QZB Series For Motor Starting at best price.

An autotransformer is a single-turn transformer, in which the primary and secondary sides are wound together with one winding, and its transformer ratio is fixed. Compared with the general transformer of the same capacity, the autotransformer is particularly economical, especially in the case of the transformation ratio close to 1, so it is used more in the high-power transmission transformer with similar voltage, and is widely used in the step-down starting box of asynchronous motor above 10 kilowatts.
