Report scope and project voltage
The available type test report applies to the tested 630 kVA / 10 kV configuration. For 11 kV, 22 kV or 33 kV projects, the insulation level, voltage ratio, tapping range, technical parameters and required documentation are confirmed separately during the project review.
Configure the 630 kVA Transformer for Your Project
A transformer should be selected from the electrical system and installation requirements, not from capacity alone. Before production, YINGBEN reviews the voltage ratio, load characteristics, impedance, enclosure, connection method and required documentation.
Routine Testing Before Shipment
Each completed transformer is inspected and tested against the approved technical specification before shipment. Agreed routine test records can be included with the order documentation.
Test scope and document format are confirmed before production, especially where the project requires specific IEC clauses, witness testing or tender documentation.

630 kVA Dry Type Transformer FAQ
Technical and commercial answers for EPC contractors, distributors and industrial project buyers.
What is a 630 kVA dry type transformer commonly used for?
A 630 kVA dry type transformer is commonly used for indoor power distribution in industrial facilities, commercial buildings, infrastructure projects and indoor substations. Final capacity selection should consider the connected load, demand factor, motor starting current, harmonics and future expansion.
Can the transformer be supplied with an 11 kV primary voltage?
Yes. The standard export offering uses an 11 kV primary voltage. The secondary voltage, vector group, tapping range, impedance and insulation level are confirmed according to the approved project specification.
Are 22 kV and 33 kV configurations available?
Yes. A 630 kVA dry type transformer can be engineered for 22 kV or 33 kV systems. The applicable standard, insulation level, ambient conditions and test documentation must be reviewed before the final proposal is issued.
Is an 11 kV type test report available for this page?
The currently available type test report covers the SCB14-630/10-NX2, 630 kVA / 10 kV tested configuration. It provides test evidence for the 630 kVA product platform but should not be described as an 11 kV certificate. Documentation for an 11 kV project is confirmed during technical review.
Can it be configured for Vietnam and Malaysia?
The transformer can be configured for 11 kV, 22 kV or 33 kV distribution systems and for tropical installation conditions. A 40°C standard ambient design or a 45°C project configuration can be reviewed according to the site temperature, ventilation, enclosure and required continuous capacity.
Which enclosure protection levels are available?
Common options include IP00, IP20 and IP23. The correct enclosure depends on the electrical room, ventilation, dust exposure, access control and cable or busbar arrangement. The enclosure should be confirmed together with the approved layout.
What information is required for an accurate quotation?
Please provide the rated capacity, primary and secondary voltage, frequency, vector group, impedance, tapping range, enclosure level, applicable standard, quantity and delivery destination. A tender specification, single-line diagram or existing transformer nameplate will improve quotation accuracy.
