Core Advantages

1.Large voltage regulation range: Within the normal tapping range, this type of transformer usually has a large voltage regulation range, generally ± 10% of the rated voltage, and can be designed up to a maximum of no more than 20%. In addition, there are many voltage regulation levels, usually nine levels, which can be designed according to user requirements.

2. Optimizing reactive power: By using vacuum on load regulating switches, tap voltage switching can be completed during load operation, maintaining the power grid at a high voltage level, optimizing reactive power distribution, reducing line losses, and thus improving the economic benefits of the power grid.

3. Reactive power zoning balance: On the premise of achieving on-site balancing of reactive power zoning, cooperate with the switching of reactive power compensation equipment (such as parallel capacitors and low-voltage reactors), adjust the tap changer, and ensure the quality of the power supply voltage to the user at all times.

4. Sturdy frame structure: The high and low voltage clamps are tightened with steel straps or upper beams and measuring beams to form a sturdy frame structure, enhancing the clamping force of the iron core and the ability to withstand transportation impacts.

Excellent insulation and heat dissipation performance: Using high-quality insulation materials and iron cores, it has stable performance and excellent insulation performance. The longitudinal oil passage of the high and low voltage coils is beneficial for heat dissipation, which can significantly reduce the temperature difference between the oil and the hot spot temperature rise inside the coils.

5. Low loss and low noise

Low loss: Through optimized design and advanced technology, this type of transformer has lower losses during operation.

Low noise: reliable operation, low noise, reaching the advanced level of similar foreign products.

6. Customization and Scalability

Customized services: Customized designs can be made according to the specific needs of users, such as adding over temperature protection devices, selecting power supply time controllers, remote control devices, etc.

Parallel operation capability: If parallel operation is required, a synchronous controller must be configured, and the number of parallel operation units cannot exceed 4.
