Comprehensive Oil-immersed Transformers Product Details:
Oil-immersed transformers are pivotal power equipment extensively utilized across power systems. These transformers are expertly crafted for voltage conversion and efficient power transmission. Specifically engineered for high current and substantial capacity demands, they stand out for their exceptional stability and reliability, making them indispensable in power systems.

 

Understanding the Model Meaning:

 

Distinctive Performance Characteristics:

1. Advanced Winding Structure:
The high-voltage winding is meticulously designed with a multi-layer cylindrical, continuous, or connecting continuous structure. This enhances the winding's shock distribution, minimizes magnetic leakage, and provides superior mechanical strength and robust short-circuit resistance.

2. Innovative Iron Core Design:
Employing high-quality cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, this design significantly reduces no-load loss and curtails no-load current, ensuring efficient performance.

3. Superior Fastening and Anti-loosening Features:
Both the core and windings are meticulously secured using innovative fastening measures. High and low voltage leads are fitted with self-locking anti-loosening nuts, coupled with a non-hanging center structure to endure transportation vibrations. Every fastener comes with secure nuts, guaranteeing they remain steadfast even during prolonged operation.

4. Precision Vacuum Processing:
Coils and cores undergo meticulous vacuum drying, while transformer oil is carefully vacuum-filtered and injected, effectively minimizing moisture within the transformer for optimal longevity.

5. Intelligent Oil Tank Design:
Crafted with corrugated sheets featuring a breathing function, the oil tank compensates for volume changes due to temperature variations. The absence of an oil storage cabinet cleverly reduces the transformer's overall height.

6. Additional Remarkable Features:
Boasting a stunning appearance, compact size, and minimal installation footprint, this product is the quintessential maintenance-free solution.
A versatile solution, extensively employed in power plants, substations, industrial and mining enterprises, and rural power grids, seamlessly integrating into power distribution systems.

 

Optimal Environment and Requirements:
Recommended Ambient Temperature Range: Ideally maintained between -25°C and +40°C for optimal performance.
Maximum Altitude Limit: Should not exceed 1000m to ensure effective operation.
Air Humidity Constraints: Should remain no more than 90% relative humidity at +25ºC.
Preferred Installation Place: Select an area devoid of corrosive gases and significant dirt for optimal longevity.

 

Essential Maintenance and Upkeep:
Conduct Regular Inspections: Frequent checks of the oil level and insulation strength test are vital. Prompt replacement of transformer oil is necessary upon identifying any issues.
Ensure Stable Operation: Achieve a stable operation by diligently preventing overloads, short circuits, and other anomalies.
Prioritize Safety Attention: Before installation, thoroughly consider plant ventilation, fire prevention, and adhere to technical specifications for precise installation.
