Frequently Asked Questions
What is this transformer used for?
It is intended for outdoor and utility distribution duty: voltage step-down for industrial plants, infrastructure projects and distribution networks. Share your network data and we will confirm the configuration.
Copper or aluminium windings – which should I choose?
Copper gives lower losses and a smaller footprint at higher cost; aluminium reduces initial cost and weight. The right choice depends on your loss capitalisation method and budget, and we supply both.
Are amorphous alloy or OLTC designs available?
Yes. Amorphous alloy core designs reduce no-load loss where the transformer runs lightly loaded for long periods. On-load tap changing suits networks with wide voltage variation. Both are built to order.
Which standards does it comply with?
Oil-immersed transformers are designed to IEC 60076 and the GB equivalent. Where your project specifies ANSI/IEEE or a local efficiency tier, confirm the applicable clauses before production.
What do you need to provide a quotation?
Rated capacity, primary and secondary voltage, frequency, vector group, winding material, tap changer requirement, altitude and quantity.
