Looking for transformer manufacturers in Yueqing? This guide profiles ten companies that publish power-transformer ranges and a local manufacturing or contact address. The selection covers oil-immersed distribution transformers, cast-resin dry-type transformers, H-class and amorphous-alloy designs, mining and marine variants, and larger power-transformer families. CANGO is included at the top of the list, with its Yueqing headquarters and multi-site manufacturing model stated clearly.
Transformer selection should start with the electrical duty and installation conditions, not with a series label. Two suppliers can both advertise an SC(B) dry-type or S13 oil-immersed family while offering different losses, impedance, temperature rise, tap range, enclosure and document scope. Use this guide to build a shortlist, then send every company the same specification so that the quotations can be compared line by line.
How this list was selected: Official company, product and contact pages were reviewed on 22 October 2026. The order is a research shortlist, not a quality, price, certification, export or “best” ranking. A published address or product range does not prove that BottomRace has audited every factory or that every model carries every approval. Confirm the legal entity, manufacturing site, exact design, current certificate and test scope before ordering.

Compare the transformer as a complete electrical specification
A transformer price is only comparable when both quotations describe the same electrical and mechanical scope. Build a technical schedule with the fields below, issue it unchanged to every shortlisted company, and require the supplier to list any deviation in writing.
| Include in your enquiry | Ask each supplier to confirm |
|---|---|
| Application and type | Distribution transformer, power transformer, dry-type, oil-immersed, mining, marine, control, isolation or special design; indoor or outdoor duty and the applicable product standard. |
| Rated power and frequency | Continuous rating, frequency, load profile, altitude, ambient temperature, seismic or transport conditions and any overload or cyclic-duty requirement. |
| Voltage ratio and insulation | Primary and secondary voltages, insulation levels, BIL or impulse requirement, system earthing and the voltage taps needed on the high-voltage winding. |
| Winding and vector group | Copper or aluminium conductor, winding construction, vector group, phase displacement, neutral arrangement and suitability for parallel operation. |
| Losses and impedance | No-load and load losses at the reference temperature, efficiency or energy-efficiency level, impedance voltage, tolerances and the calculation basis. |
| Cooling and temperature rise | ONAN, ONAF, AN or AF cooling as applicable, fan control, insulation class, temperature-rise limit, hot-spot basis and the rated conditions for those figures. |
| Tap changer | Off-circuit or on-load type, tap range and step, location, operating voltage, control and indication, and whether the tap changer is included in the type-test scope. |
| Core and construction | Silicon-steel or amorphous core, wound or stacked core, tank or enclosure construction, corrosion protection, lifting and transport provisions, and pressure-relief or oil-containment features. |
| Bushings and connections | Bushing type and ratings, cable boxes, terminal arrangement, phase barriers, earthing points, current-transformer or metering interfaces and the cable or busbar connection details. |
| Protection and monitoring | Temperature controller, fans, alarm and trip contacts, pressure or oil-level devices, moisture control, surge protection and any project-specific relay or sensor interface. |
| Enclosure and environment | IP rating, enclosure material and finish, ventilation, pollution or corrosive atmosphere, humidity, outdoor UV exposure, fire or seismic requirement and installation clearances. |
| Tests and documents | Routine tests, type tests, special tests, third-party witness or report requirements, applicable standard and the exact model, rating and production entity covered by each document. |
| Nameplate and packing | Nameplate language and data, serial and batch identification, drawing revision, manual language, packing, transport protection, lifting points and shipping dimensions and mass. |
| Production and change control | Factory address, subcontracting or additional production base, approved drawing revision, component or material substitution rules and written notification before a change. |
Do not compare transformer prices from series names alone. A quotation for an S13, SC(B)18 or amorphous-alloy unit is not complete until the losses, impedance, temperature rise, tap range, enclosure, accessories and test scope are stated. Ask for the guaranteed values and the tolerance basis in the order, not only in a brochure.
For a project that combines a transformer with switchgear or a prefabricated substation, define the battery limits. State who supplies the high-voltage incoming section, low-voltage outgoing section, protection and metering, auxiliary supply, cable boxes, foundation interface and site testing. A single package price can hide a large difference in scope unless the interface schedule is written down.
What to inspect during a transformer factory visit
A useful visit follows the quoted transformer through the production route and checks the operations that control losses, insulation and reliability. Confirm the production address before travelling and ask which operations are performed on site or by a subcontractor.
- Incoming materials: review the identification and inspection of electrical steel, conductor, insulation paper or resin, tank plate, bushings, tap changers and purchased protection components.
- Core preparation: inspect core cutting, stacking or winding, insulation between laminations, clamping and the controls used to prevent burrs, short circuits or contamination.
- Winding and insulation: compare the winding arrangement and insulation with the approved drawing; check conductor handling, interlayer insulation, transposition, end insulation and clearances.
- Drying and oil processing: for oil-immersed units, review the drying, vacuum and oil-treatment records; for dry-type units, review the casting, curing or impregnation process and temperature controls.
- Tank and enclosure fabrication: check plate preparation, welding, leak testing, surface treatment and the protection of sealing surfaces and bushings before assembly.
- Final assembly: compare the tap changer, bushings, cable boxes, terminals, earthing, fans, temperature devices and nameplate with the order and approved drawing.
- Electrical tests: observe or review ratio, winding resistance, insulation resistance, dielectric, no-load and load-loss tests, plus the applicable impulse or partial-discharge tests for the selected design.
- Document and change control: check how the factory links the serial number to drawings, test results and nameplate data, and how it notifies buyers before a material, component or manufacturing-site change.

Questions transformer buyers often ask
Should I choose an oil-immersed or dry-type transformer?
The choice depends on the installation, fire and environmental requirements, load profile, available space, maintenance capability and project standard. Oil-immersed units are common for distribution and power applications; dry-type units can be preferred where oil containment or fire risk needs a different solution. Do not select the type from price alone. Ask the project engineer to confirm the required standard, enclosure, cooling and site conditions.
Are S13, S20 and SC(B)18 comparable series names?
They describe different families and generations, not a complete specification. Even within one family, losses, impedance, tap range and construction can vary. Compare the guaranteed electrical values, drawings and test scope for the exact model. Do not assume that a higher number automatically means a better transformer for your application.
Why does the production site matter when the company is in Yueqing?
A company can have its headquarters or sales office in Yueqing while some models are manufactured at another facility. CANGO, for example, publishes production bases in Yueqing and Wenling. A factory visit, certificate and contract should therefore identify the actual manufacturing site for the quoted model.
What documents should I request before approving the order?
Ask for the approved outline drawing, electrical schedule, guaranteed losses and impedance, nameplate artwork, test plan, applicable type-test or certificate scope, installation and maintenance instructions, packing drawing and commercial terms. Confirm that the document identifies the exact model, rating, factory and legal entity. A management-system certificate alone is not a product type test.
Can I use one transformer quotation to compare every supplier?
Only if every supplier receives the same technical schedule. Add the application, voltages, rating, frequency, vector group, losses, impedance, cooling, tap range, protection, enclosure, tests and documentation requirements. Require each quotation to list deviations and the production site. A lower price may reflect a smaller enclosure, a different loss level, excluded accessories or a different test scope.
