Oil-immersed Transformers Product Details: A comprehensive look at the technical and functional aspects of our oil-immersed transformers.
Oil-immersed transformers are pivotal power equipment in electrical systems, crafted for seamless voltage conversion and robust power transmission. These units are engineered to meet high current and large capacity demands with unwavering stability and reliability, making them indispensable in modern power infrastructures.

 

Model Meaning: Unravel the specifics behind our model nomenclature; a guide to understanding the transformative elements inherent in each design.

 

Performance Characteristics: Discover the exceptional features and advantages that distinguish our transformers in the industry.

1. Winding structure: Ingeniously designed multi-layer cylindrical windings enhance magnetic shock distribution, minimize leakage, and boast high mechanical integrity for outstanding short-circuit resilience.
The high-voltage winding adopts a sophisticated multi-layer cylindrical, continuous, or linking continuous structure, optimizing shock distribution, minimizing magnetic leakage, and ensuring superior mechanical strength and exceptional short-circuit resistance.

2. Iron core design: Utilizing premium cold-rolled grain-oriented silicon steel sheets with full diagonal seam stacking, we significantly reduce no-load loss and current, enhancing efficiency.
Adoption of premium cold-rolled grain-oriented silicon steel sheets with an innovative full diagonal seam stacking method, vastly reduces no-load loss and current, elevating performance.

3. Fastening and anti-loosening: Our core and windings are secured with advanced fastening systems, featuring self-locking anti-loosening nuts, built to endure transportation vibrations and maintain integrity over long-term operations.
The core and windings are meticulously fastened with cutting-edge techniques, including self-locking anti-loosening nuts for high and low-voltage leads. This non-hanging center structure withstands transportation-induced vibrations, ensuring unwavering performance and stability during extended operations.

4. Vacuum processing: Employing state-of-the-art vacuum drying for coils and cores, along with vacuum-filtered transformer oil injection, we mitigate moisture presence, optimizing the transformer's longevity and efficiency.
Coils and cores undergo a rigorous vacuum drying process, while transformer oil is meticulously vacuum filtered and injected, significantly reducing moisture levels within the transformer for enhanced durability.

5. Oil tank design: Featuring a corrugated sheet oil tank with breathability, it adapts to oil volume changes due to temperature fluctuations and omits the need for an oil storage cabinet, thereby reducing transformer height.
The oil tank, crafted with a versatile corrugated sheet, compensates for oil volume variations linked to temperature shifts, eliminating the need for an oil storage cabinet and effectively reducing the transformer's overall height.
