Section Header: Performance Characteristics:

1. Intricate Winding Structure:
Our high-voltage winding is crafted with a multi-layer cylindrical, continuous, or connecting continuous design. This enhances the winding's shock distribution, minimizes magnetic leakage, and provides high mechanical strength with robust short-circuit resistance.

2. Innovative Iron Core Design:
Employing premium high-quality cold-rolled grain-oriented silicon steel sheets with an advanced full diagonal seam stacking method, our design significantly decreases no-load loss and curbs no-load current, optimizing energy efficiency.

3. Advanced Fastening and Anti-loosening Measures:
Each core and winding is meticulously secured with advanced fastening techniques. High-quality self-locking anti-loosening nuts are used for critical parts like high and low voltage leads, adhering to a non-hanging center structure to endure transport vibrations. All fasteners are fortified with nuts, ensuring long-term operational stability without loosening.

4. State-of-the-Art Vacuum Processing:
Our specialized vacuum drying process for coils and cores, coupled with vacuum-filtered transformer oil injection, effectively minimizes internal moisture, enhancing transformer longevity and efficiency.

5. Sophisticated Oil Tank Design:
Featuring a corrugated sheet oil tank with a unique breathing capability, our design accommodates oil volume changes due to temperature fluctuations without the need for an oil storage cabinet, thereby reducing the transformer's overall height.

6. Distinctive Features:
Its exquisite appearance, compact size, and minimal installation footprint make this transformer an ideal, maintenance-free solution for diverse applications.
Our transformers are extensively utilized across power plants, substations, industrial and mining sectors, as well as rural power grids, playing a vital role in power distribution systems.

 

Section Header: Environment and Requirements:
Parameter: Ambient Temperature: Typically, ambient temperatures should range between -25°C and +40°C for optimal performance.
Parameter: Altitude Limit: Operational altitude should not exceed 1000 meters to maintain efficiency.
Parameter: Air Humidity: Maintain relative humidity at no more than 90% (at +25ºC) for optimal functionality.
Parameter: Installation Place: Choose an installation site that is devoid of corrosive gases and significant dirt to ensure longevity and performance.

 

Section Header: Maintenance and Upkeep:
Maintenance Task: Regular Inspection: Regularly inspect the oil level and conduct oil insulation strength tests. Promptly address any issues by replacing transformer oil to sustain optimal performance.
Operational Assurance: Stable Operation: Ensure the transformer operates steadily, taking preventive measures against overload, short circuits, and other anomalies.
Safety Precaution: Safety Attention: Prior to installation, consider plant ventilation and fire prevention measures. Follow technical guidelines for accurate installation.
