Third-Party Type Test Report Available for S20-M Transformer Series
Yingben provides third-party type test documentation for the S20-M oil immersed transformer series. The registered model range covers S20-M-630～2500/10-NX2, including the 630 kVA capacity.
The available type test report is based on an S20-M-2000/10-NX2 2000 kVA transformer sample from the same registered series. This documentation provides supporting technical evidence for project evaluation and transformer series verification.
The 630 kVA transformer is included in the registered S20-M 630–2500 kVA model range. The third-party type test sample shown in the report is the 2000 kVA model and should not be interpreted as an individual 630 kVA type test.
Model Registration
Registered model range covering S20-M-630～2500/10-NX2.
Third-Party Type Test Report
Type test documentation based on the S20-M-2000/10-NX2 2000 kVA sample.
Test Results
Key third-party test information and qualification results for the tested transformer.
Relevant test documentation can be provided for customer technical evaluation and project documentation requirements.
Routine Testing Before Delivery
Each 630 kVA oil immersed transformer is subject to routine factory testing before shipment to verify electrical performance, connection accuracy and manufacturing quality against the approved project specification.
Voltage Ratio Test
Verifies that the transformer voltage ratio matches the approved technical design.
Vector Group Verification
Confirms transformer winding connection and phase displacement configuration.
Winding Resistance Test
Checks winding resistance values as part of routine electrical performance verification.
No-Load Loss Test
Measures no-load performance before the transformer leaves the manufacturing facility.
Load Loss & Impedance Test
Verifies load loss and short-circuit impedance against the approved transformer specification.
Insulation Performance Test
Checks insulation performance as part of the transformer's final factory inspection and testing process.
Routine factory testing is carried out for each transformer before delivery. Relevant test records can be provided according to project and customer documentation requirements.
