Comprehensive Overview of Oil-Immersed Transformers:
Our oil-immersed transformers stand as a pinnacle of power equipment, extensively utilized across power systems for seamless voltage conversion and efficient power transmission. These transformers are robustly engineered to address the demands of high current and substantial capacity with unparalleled stability and reliability.

 

Model Significance:

 

Distinguished Performance Characteristics:

1. Advanced Winding Structure:
The high-voltage winding is crafted using a multi-layer cylindrical, continuous, or connecting continuous structure, significantly enhancing shock distribution, reducing magnetic leakage, and providing exceptional mechanical strength alongside robust short-circuit resistance.

2. Premium Iron Core Design:
Utilizing superior cold-rolled grain oriented silicon steel sheets with an innovative full diagonal seam stacking method, this design significantly diminishes no-load loss and no-load current, ensuring peak performance.

3. Secure Fastening and Anti-Loosening Features:
Both core and windings are meticulously secured with advanced fastening techniques. With self-locking anti-loosening nuts, the structure adopts a non-hanging center capable of withstanding the rigors of transport-induced vibrations. All fasteners are reinforced with secure nuts, guaranteeing stability throughout prolonged operations.

4. Precision Vacuum Processing:
Through vacuum drying of coils and cores, coupled with vacuum-filtered and injected transformer oil, this process ensures minimal moisture presence within the transformer, fortifying its longevity and efficiency.

5. Innovative Oil Tank Design:
The oil tank features corrugated sheets with a breathing function, accommodating oil volume changes due to temperature variations, eliminating the need for an oil storage cabinet, thereby reducing the transformer's height and optimizing space usage.

6. Additional Features:
With an aesthetically pleasing design, compact size, and minimal installation footprint, it emerges as an ideal maintenance-free solution.
These transformers are essential in power plants, substations, and industrial and mining enterprises, and serve as a cornerstone for rural power grids, enhancing distribution system efficiency.

 

Environmental Conditions and Requirements:
Operating Temperature Range: Optimal functioning is ensured between temperatures of -25°C and +40°C.
Maximum Altitude: Effectively operational at altitudes not exceeding 1000 meters.
Humidity Conditions: Designed to perform in environments with relative humidity not exceeding 90% at +25ºC.
Preferred Installation Locations: Select locations devoid of corrosive gases and significant dirt accumulation to maintain optimal performance.

 

Maintenance and Regular Upkeep:
Routine Inspections: It's crucial to consistently monitor the oil level and conduct oil insulation strength tests, with prompt transformer oil replacement upon identifying issues.
Ensuring Stable Operation: To maintain the transformer's stable operation, preventative measures against overload, short circuit, and other anomalies are essential.
Safety Precautions: Prior to installation, evaluate the plant's ventilation and fire safety measures, ensuring all technical specifications are meticulously followed for correct installation.
