Suggested equipment
Indicative: kVA = kW ÷ PF × (1 + growth), sized for ≤ 90% loading. Final rating, impedance and losses are confirmed by our engineers.
05 — Manufacturing
Built on real production lines — not a trading desk.
Our transformers are built on real production lines: foil and wire winding, vacuum resin casting, oil-filling lines and a full routine-test bay.
06 — Quality & certification
Every unit tested before it ships.
Routine tests on 100% of units, type tests by a CNAS-accredited national laboratory, and a management system certified to ISO 9001, ISO 14001 and ISO 45001.

Questions buyers ask
Short answers from our engineers. Ask anything else in the inquiry form.
Oil-immersed or dry-type: which transformer should I choose?
Choose oil-immersed for outdoor yards and the lowest cost per kVA; choose cast-resin dry type for indoor rooms, high-rise buildings, hospitals and anywhere fire rules restrict oil.
How do I size a distribution transformer?
Divide the maximum demand in kW by the power factor to get kVA, add margin for future growth, then pick the next standard rating so the transformer runs below about 90% load. Our sizing tool does this in seconds.
Which standards do your transformers meet?
IEC 60076 (oil-immersed), IEC 60076-11 (dry type), IEC 62271-202 (prefabricated substations) and the Chinese GB 1094 / GB/T 10228 / GB/T 6451 series. Other voltages, frequencies and standards are engineered to order.
What is the difference between S11, S13 and amorphous transformers?
They are energy-efficiency levels. S13 has about 20–30% lower no-load loss than S11, and amorphous-alloy cores cut no-load loss by about 70% versus S11 — the best choice where transformers run lightly loaded.
What is the typical lead time?
Standard distribution transformers and substations usually ship within a few weeks of drawing approval; power transformers take longer. We confirm a firm date with every quotation.
Can I inspect or witness tests before shipment?
Yes. You can attend factory acceptance tests in person or by live video, or appoint a third-party inspector. Test reports for your serial numbers are supplied with the shipment.
