Comprehensive Oil-Immersed Transformers Product Details:
Our oil-immersed transformers are essential power equipment, expertly crafted for extensive use in power systems. Primarily tasked with sophisticated voltage conversion and seamless power transmission, they are engineered to meet the demanding needs of high current and large capacity transformers. Enjoy unmatched stability and unwavering reliability.

 

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 design significantly enhances the winding's shock distribution, ensures minimal magnetic leakage, and offers superior mechanical strength with exceptional short-circuit resistance.

2. Innovative Iron Core Design:
Our design incorporates premium cold rolled grain-oriented silicon steel sheets. The full diagonal seam stacking method effectively reduces no-load loss and no-load current, optimizing operational efficiency.

3. Secure Fastening and Anti-Loosening Features:
We've equipped the core and windings with robust fastening measures. High and low voltage leads include self-locking anti-loosening nuts. The non-hanging center structure confidently withstands transportation vibrations. Each fastener comes with secure nuts to prevent loosening during extended operations.

4. Precision Vacuum Processing:
Utilizing advanced vacuum drying techniques for coils and cores, and vacuum-filtered transformer oil injection, we effectively minimize moisture, ensuring reliability.

5. Ingenious Oil Tank Design:
Our oil tank features corrugated breathing sheets, adeptly compensating for oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's height.

6. Additional Remarkable Features:
Boasting a beautiful design, compact size, and minimal installation footprint, our transformers are the ideal maintenance-free solution for modern needs.
Perfectly suited for power plants, substations, industrial, mining enterprises, and rural power grids. A cornerstone in any power distribution system.

 

Environmental Considerations and Requirements:
Optimal Ambient Temperature Conditions: Typically required to remain between -25°C and +40°C.
Suitable Altitude Limitations: Not to exceed 1000 meters.
Appropriate Air Humidity: Should not exceed 90% relative humidity at 25ºC.
Ideal Installation Environment: Select areas devoid of corrosive gases and noticeable dirt for optimal performance.

 

Maintenance and Upkeep Essentials:
Frequent Regular Inspections: Conduct regular checks on oil levels and perform oil insulation strength tests. Promptly replace transformer oil if any issues are detected.
Ensuring Stable Operation: Maintain stable transformer operations by preventing overloads, short circuits, and other abnormalities.
Crucial Safety Precautions: Prioritize plant ventilation and fire prevention before installation. Adhere to technical specifications for precise setup.
