🔹 Product Overview
The 1000 kVA distribution transformer (1 MVA transformer) is designed to provide efficient and reliable voltage conversion from medium voltage to low voltage in power distribution systems. It is widely used in industrial plants, commercial facilities, infrastructure projects, and utility networks where stable and continuous power supply is essential.
Manufactured by Sichuan Yawei Transformer, this transformer is engineered with advanced core materials, optimized winding structures, and robust mechanical design to ensure low energy loss, high operational stability, and long service life.
This model supports a wide range of voltage configurations, including 11kV, 22kV, and 33kV on the primary side, and 400V, 415V, 480V, or customized voltages on the secondary side, making it suitable for global applications.
🔹 Key Features and Benefits
✔ High Efficiency and Energy Saving
The transformer is built with high-permeability CRGO silicon steel core, which significantly reduces no-load losses and improves overall efficiency. The optimized electromagnetic design ensures minimal energy waste, helping end users reduce operational costs over time.
✔ Superior Thermal Performance
Equipped with an oil-immersed cooling system (ONAN / ONAF), the transformer offers excellent heat dissipation. The insulating oil acts as both a coolant and dielectric medium, ensuring stable performance even under continuous full-load operation.
✔ Strong Overload Capability
Designed for demanding industrial environments, the 1000 kVA transformer can withstand short-term overload conditions without compromising performance, making it ideal for heavy-duty applications.
✔ Flexible Customization Options
To meet different project requirements, the transformer can be customized in:
- Voltage levels (HV/LV)
- Frequency (50Hz / 60Hz)
- Vector group (Dyn11, Yyn0, etc.)
- Tap changer (off-load / on-load)
- Cooling methods
- Insulation oil type (mineral oil / ester oil)
✔ Durable and Weather-Resistant Design
The tank is constructed with high-quality steel and anti-corrosion coating, suitable for outdoor installations in harsh environments such as high humidity, coastal regions, or industrial zones.
✔ Low Noise Operation
The core structure and assembly process are optimized to reduce vibration and noise levels, making it suitable for urban and commercial installations.

🔹 Working Principle
The 1000 kVA distribution transformer operates based on the principle of electromagnetic induction. When alternating current flows through the primary winding, it generates a magnetic field in the transformer core. This magnetic field induces a voltage in the secondary winding, effectively stepping down the voltage to a usable level.
The transformation ratio is determined by the number of turns in the primary and secondary windings, ensuring accurate voltage conversion and stable output.
