Frequently Asked Questions

What types of transformers do you produce?

We specialize in oil-immersed power transformers (up to 330kV), dry-type transformers, rectifier transformers, furnace transformers, and combined substations.

Which international standards do your products follow?

Our products are designed and manufactured in full compliance with IEC, CE, ISO, GB, and ANSI standards.

What testing is performed before the product leaves the factory?

Every unit undergoes mandatory routine tests (resistance, ratio, losses). We also conduct type tests like lightning impulse and special tests like noise level and short circuit stability upon request.

Do you offer on-site technical support?

Yes, we provide comprehensive engineering services including installation guidance, commissioning, and on-site training for your technical staff.

What is your standard warranty period?

We provide a 12-month quality and performance warranty starting from the date of operation or delivery as per the contract terms.

Can clients inspect the manufacturing process?

Absolutely. Clients are permitted and encouraged to visit our factory for supervision, guidance, and to witness acceptance testing during the manufacturing process.
