Frequently Asked Questions
What is the advantage of amorphous alloy cores?
Amorphous alloy cores have significantly lower no-load loss than conventional silicon steel, reducing energy consumption during the long periods when the transformer runs lightly loaded.
Are amorphous transformers suitable for utility distribution?
Yes. They are widely used on utility distribution networks where energy efficiency and total cost of ownership are primary selection criteria.
What standards apply to this transformer?
The unit is designed and tested to the applicable IEC or ANSI standards, with routine tests performed on every unit.
Can the transformer be customized for my network voltage?
Yes. Voltage ratio, tap range, vector group and impedance are configured to your network requirements.
What is the delivery lead time?
Standard delivery is 30 days after drawing approval, with the schedule confirmed against your final specification.
