Oil-immersed Transformers Product Details:
Our oil-immersed transformers stand at the forefront of power equipment technology, expertly crafted for seamless voltage conversion and reliable power transmission. Engineered to meet the demanding needs of high current and large capacity transformers, they offer unparalleled stability and dependability within power systems.

 

Model Meaning:

 

Performance Characteristics:

1. Winding Structure:
Featuring high-voltage windings crafted with multi-layer cylindrical, continuous, or connecting continuous structures, our design significantly enhances shock distribution, minimizes magnetic leakage, and boosts mechanical strength, ensuring exceptional short-circuit resistance.

2. Iron Core Design:
Utilizing premium cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking technique, we achieve reduced no-load losses and minimized no-load current, optimizing performance.

3. Fastening and Anti-Loosening:
Both core and windings are meticulously secured with fastening measures. High and low voltage leads feature self-locking anti-loosening nuts, and a non-hanging center structure withstands transit vibrations. All fasteners are fortified with nuts to prevent operational loosening over time.

4. Vacuum Processing:
Employing advanced vacuum drying for coils and cores, followed by meticulous vacuum filtration and oil injection, effectively minimizes moisture content, ensuring efficient transformer operation.

5. Oil Tank Design:
The state-of-the-art oil tank, incorporating corrugated sheets with breathing capabilities, adapts to oil volume changes due to temperature variations, eliminating the need for an oil storage cabinet and lowering the transformer's profile.

6. Additional Features:
Complementing its functionality, the transformer boasts a sleek design, compact size, and minimal installation footprint, epitomizing an ideal maintenance-free solution.
Our transformers are the preferred choice for power plants, substations, industrial and mining sectors, and rural power grids, playing a pivotal role in power distribution systems.

 

Environment and Requirements:
Ambient Temperature: Optimally functions within a temperature range of -25°C to +40°C.
Altitude Limit: Designed for installation at altitudes not exceeding 1000 meters.
Air Humidity: Operates efficiently in environments with a relative humidity not exceeding 90% at 25ºC.
Installation Place: Choose locations free from corrosive gases and significant dirt accumulation to ensure optimal performance.

 

Maintenance and Upkeep:
Regular Inspection: Regularly monitor oil levels and conduct oil insulation strength tests. Address any issues promptly by replacing transformer oil as needed.
Stable Operation: Maintain stable transformer operations by preventing overloads, short circuits, and other unusual occurrences.
Safety Attention: Prior to installation, ensure the site has adequate ventilation and fire safety measures. Follow all technical specifications for accurate installation.
