Tips: What is a 10 kVA isolation transformer?
10 kVA isolation transformer is a step up & step down 3 phase isolation transformer whose input windings and output windings have electrical isolation, it can avoid accidentally contact with the charged body at the same time. The transformer can isolate the respective current of primary and secondary windings. Its principle is the same with ordinary dry-type transformer, also use electromagnetic induction principle to isolate primary power circuit and secondary circuit ground floating to ensure electrical safety. ATO isolation transformers are widely used for control power of general circuit, power of safety lighting and indicator light in the electronics industry, mining enterprises and machine equipment.
