Product Introduction
IEC 60076: Power Transformer Technical Specification
XWA Power transformers are designed and manufactured in strict compliance with IEC 60076 (Power Transformers), IEC 60076-11 (Dry-Type Transformers), and GB/T 1094 national standards. The following table outlines the most commonly supplied models and their core technical parameters, suitable for power grid distribution, industrial, commercial, and renewable energy applications.
| Model | Type | Voltage Class | Capacity Range | Typical Applications |
|---|---|---|---|---|
| S-11M | Oil-immersed | 10kV/0.4kV | 30–2,500kVA | Power grid distribution · Rural electrification |
| S13-M | Oil-immersed | 10kV/0.4kV | 30–2,500kVA | Low-loss urban grid · Smart grid |
| SZ11 | Oil-immersed OLTC | 10kV–110kV | 1,000–63,000kVA | Substation · Industrial plant |

Application Scenarios — Where Power Transformers Are Used Power Grid Distribution Application
Power Grid & Utility Distribution
oil-immersed and dry-type transformers are widely deployed in primary and secondary power distribution networks operated by national grid companies and regional utilities. Our transformers handle the step-down and step-up functions critical to stable grid operation.
Typical products: S11-M (10kV), S13-M (10kV), SZ11 (35kV/110kV OLTC)
Typical capacity: 100kVA – 63,000kVA
Standards: IEC 60076 · GB/T 1094
Industrial Plant & Factory Power Supply
Manufacturing facilities, petrochemical plants, steel mills, cement factories, and data centres require reliable, low-maintenance transformer solutions. XWA dry-type transformers (SCB series) are particularly suited for indoor installation where fire safety and low noise are priorities.
Typical products: SCB13, SCB15 (dry-type), SZ11 (oil, with OLTC)
Typical capacity: 500kVA – 20,000kVA
Standards: IEC 60076-11 · GB/T 10228
Solar, Wind & Renewable Energy Projects
step-up transformers for solar PV and wind farms are engineered to handle high-frequency harmonics generated by inverters, DC offset conditions, and the demanding load cycles of utility-scale renewable energy plants.
Typical products: Dedicated PV step-up transformer, BESS transformer
Typical capacity: 500kVA – 10,000kVA per unit
Voltage: 0.27kV/0.315kV → 10kV/35kV
Standards: IEC 60076 · IEC 61936
