Model Meaning: Comprehensive insights into the nomenclature and specifications of our transformer models for informed decision-making.

 

Performance Characteristics: Unveiling the exceptional features that enhance performance and resilience in our transformers.

1. Winding structure: A robust high-voltage winding with a multi-layer cylindrical, continuous, or connecting continuous structure ensures superior shock distribution, minimized magnetic leakage, and formidable mechanical strength, offering remarkable short-circuit resistance.
The high-voltage winding adopts multi-layer cylindrical, continuous or connecting continuous structure, which improves the shock distribution of the winding, small magnetic leakage, high mechanical strength and strong short-circuit resistance.

2. Iron core design: Integrating prime cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, our design significantly reduces no-load loss and no-load current, enhancing operational efficiency.
Adoption of high quality cold rolled grain oriented silicon steel sheet with full diagonal seam stacking method reduces no-load loss and no-load current.

3. Fastening and anti-loosening: Ingeniously designed for durability, our transformers include self-locking anti-loosening nuts and non-hanging center structures, ensuring steadfast performance even during transportation. Every fastener is secured with nuts to maintain integrity over prolonged usage.
The core and windings are each fastened with fastening measures, and the fastening parts such as the high and low voltage leads of the body are equipped with self-locking anti-loosening nuts, and the structure of the non-hanging center is adopted, which can withstand the vibration of transportation. All fasteners are equipped with fastening nuts to ensure that the fasteners do not loosen during long-term operation.

4. Vacuum processing: Each coil and core undergoes precise vacuum drying, while transformer oil is expertly vacuum filtered and injected, thereby reducing moisture to enhance longevity and performance.
Coils and cores are vacuum dried, and transformer oil is vacuum filtered and injected in a process that minimizes moisture inside the transformer.

5. Oil tank design: Our innovative oil tank features corrugated sheets with a breathing function, adapting seamlessly to temperature-induced oil volume changes while eliminating the need for an oil storage cabinet, thus reducing the transformer's height.
The oil tank adopts corrugated sheet with breathing function to compensate for the volume change of oil due to temperature change, there is no oil storage cabinet, which reduces the height of the transformer.
