Short Answer
SCB11, SCB12, and SCB14 are dry-type transformer series that should be selected by voltage class, capacity, loss requirement, installation environment, enclosure, cooling method, and required certificates or reports.
Start With Voltage and Capacity
SCB dry-type transformer selection should begin with the project voltage class and required capacity. A buyer should not only ask for a series name, because the same series can still vary by rated capacity, voltage ratio, impedance, connection group, enclosure, and cooling arrangement.
For Jinxing Electric procurement, SCB11 is commonly mapped to 10kV class indoor distribution, SCB12 to 20kV class distribution, and SCB14 to 35kV class projects where a buyer may also care about lower losses and project documentation.
- SCB11: common 10kV class dry-type transformer option.
- SCB12: common 20kV class dry-type transformer option.
- SCB14: common 35kV class dry-type transformer option.
- Always confirm capacity, voltage ratio, impedance, enclosure, and cooling method.
Compare Losses, Indoor Environment, and Enclosure
Dry-type transformers are often used in indoor distribution rooms, factories, commercial buildings, and infrastructure projects. The buyer should confirm ventilation, operating temperature, dust or humidity exposure, installation clearance, and whether an enclosure is required.
If two suppliers quote different SCB series or different loss levels, the prices are not directly comparable. Ask each supplier to state no-load loss, load loss, temperature rise, insulation class, noise level, and routine test document availability.
What to Send for a Fast Quotation
A complete request should include capacity, primary and secondary voltage, frequency, phase, connection group, impedance requirement, enclosure grade, installation environment, and destination market.
Jinxing Electric can support quotation with product images, certificates, reports, drawings, and packing details when the buyer needs documents for tender review, engineering approval, or import preparation.

FAQ
1. Are SCB11, SCB12, and SCB14 interchangeable?
No. They may serve different voltage classes, loss requirements, and project specifications. Buyers should compare the full technical sheet instead of only the series name.
2. What documents should I request for an SCB dry-type transformer?
Ask for technical data, outline drawing, routine test reference, certificate or report where available, packing details, and quotation assumptions.
