Oil-immersed Transformers Product Details: Dive deep into the exceptional specifics of our oil-immersed transformers, engineered for excellence.
Oil-immersed transformers stand as vital power equipment in energy systems, primarily facilitating voltage conversion and seamless power transmission. Crafted to address high current and substantial capacity demands, these transformers offer unparalleled stability and reliability in power systems.

 

Model Meaning: Decode the model specifications to understand the innovative technology encapsulated in each transformer.

 

Performance Characteristics: Discover the elite attributes that make our transformers a preferred choice for efficiency and reliability.

1. Winding structure: Expertly engineered to enhance shock distribution, minimize magnetic leakage, and maximize mechanical strength, ensuring robust short-circuit resistance.
The high-voltage winding features a multi-layer cylindrical design, providing continuous or connecting continuous structure. This enhances shock distribution of the winding, minimizes magnetic leakage, and offers substantial mechanical strength with strong short-circuit resistance.

2. Iron core design: Optimized using premium cold-rolled grain-oriented silicon steel sheets with a diagonal seam stacking methodology to significantly reduce both no-load loss and no-load current.
Our adoption of high-quality cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method ensures a remarkable reduction in no-load loss and minimizes no-load current.

3. Fastening and anti-loosening: Designed with self-locking anti-loosening nuts for vibration resilience during transport, ensuring all fasteners maintain integrity throughout extended operational periods.
The core and windings are secured with robust fastening measures. Key components, including the high and low voltage leads, are equipped with self-locking anti-loosening nuts. Our non-hanging center structure safeguards against transport-induced vibrations. All fasteners come with secure nuts, ensuring stability during long-term use.

4. Vacuum processing: The innovative vacuum drying of coils and cores, coupled with vacuum filtering and injection of transformer oil, decisively reduces moisture content within the transformer.
Coils and cores undergo vacuum drying, and the transformer oil is vacuum filtered and injected, significantly minimizing moisture ingress within the transformer.

5. Oil tank design: Features a corrugated sheet with breathing capability to adapt to oil volume changes from temperature variations, eliminating the need for an oil storage cabinet and reducing the transformer's height.
The oil tank incorporates corrugated sheets with a breathing function to adjust for oil volume changes due to temperature fluctuations, effectively eliminating the necessity for an oil storage cabinet and consequently lowering the transformer's height.
