Performance Characteristics:

1. Winding structure:
Our state-of-the-art high-voltage winding employs a multilayer cylindrical, continuous, or connecting continuous structure. This innovative design ensures enhanced shock distribution, minimal magnetic leakage, remarkable mechanical strength, and robust short-circuit resistance.

2. Iron core design:
Incorporating premium cold-rolled grain-oriented silicon steel sheets and advanced full diagonal seam stacking, this design effectively minimizes no-load loss and no-load current, offering superior energy efficiency.

3. Fastening and anti-loosening:
We integrate comprehensive fastening measures for both the core and windings. High and low voltage leads are secured with self-locking anti-loosening nuts, adopting a non-hanging center structure to endure transportation vibrations. All fasteners include robust nuts to maintain stability during long-term use.

4. Vacuum processing:
Employing meticulous vacuum processing, both coils and cores undergo vacuum drying. Transformer oil is vacuum filtered and injected, significantly reducing moisture levels within the transformer, enhancing its longevity and performance.

5. Oil tank design:
The ingeniously designed oil tank uses corrugated sheets with a breathing function, adeptly compensating for oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing the transformer's height.

6. Other features:
Showcasing a sleek, compact design, our transformers require minimal installation space and are maintenance-free, making them the ideal choice for modern applications.
These transformers are extensively employed in power plants, substations, industrial, mining enterprises, and rural power grids, forming a crucial part of the power distribution system.

 

Environment and Requirements:
Ambient temperature: Optimally designed to operate efficiently between temperatures of -25°C and +40°C.
Altitude limit: Engineered for altitudes not exceeding 1000 meters.
Air humidity: Maintains performance under relative humidity not exceeding 90% at +25ºC.
Installation place: Select locations devoid of corrosive gases and prominent dirt, ensuring longevity and optimal functionality.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent assessments of oil levels and test oil insulation strength. Promptly replace transformer oil upon detecting any issues to uphold performance.
Stable operation: Ensure the transformer operates smoothly by avoiding overloads, short circuits, and other abnormalities, preserving its peak functionality.
Safety attention: Before installation, prioritize plant ventilation, fire prevention, and adhere to technical specifications for correct installation, safeguarding the longevity and safety of the transformer.
