Oil-immersed Transformers Product Details: Unveil the remarkable attributes of our oil-immersed transformers.
Oil-immersed transformers are pivotal power equipment, extensively utilized in power systems for their superior voltage conversion and power transmission capabilities. They are meticulously engineered to meet high current and large capacity demands, offering exceptional stability and reliability.

 

Model Meaning: Understand the significance behind our model designations.

 

Performance Characteristics: Discover the exceptional features that set our transformers apart.

1. Winding structure: Innovative designs for optimal performance.
The high-voltage winding boasts a multi-layer cylindrical, continuous structure that enhances shock distribution, minimizes magnetic leakage, and offers high mechanical strength with superb short-circuit resistance.

2. Iron core design: Meticulously crafted for efficiency.
Utilizing high-quality cold rolled grain-oriented silicon steel sheets and a full diagonal seam stacking method, our design significantly reduces no-load loss and no-load current for superior performance.

3. Fastening and anti-loosening: Secure and robust construction.
Core and windings are firmly secured with advanced fastening methods. Equipped with self-locking anti-loosening nuts and a non-hanging center structure, our transformers withstand transportation vibrations with ease. All fasteners include locking nuts to maintain integrity throughout prolonged use.

4. Vacuum processing: Precision care for longevity.
Vacuum drying of coils and cores, along with vacuum-filtered oil injection, ensures minimal moisture content, enhancing the transformer's durability and efficiency.

5. Oil tank design: Clever engineering for adaptability.
Our oil tank features corrugated sheets with breathing capabilities that adapt to oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and consequently lowering the transformer's profile.

6. Other features: Compact and efficient.
Our transformers boast a sleek design, minimal volume, and reduced installation area requirements, making them the quintessential maintenance-free solution.
Versatile applications extend to power plants, substations, industrial, mining enterprises, and rural power grids within the power distribution framework.

 

Environment and Requirements: Tailored for diverse conditions.
Ambient temperature: Suitably designed for varied climates. Generally optimally functions between -25°C and +40°C.
Altitude limit: Adaptable to different elevations. Not exceeding 1000m to maintain performance integrity.
Air humidity: Engineered for humidity resilience. Maintains efficiency with relative humidity under 90% at +25ºC.
Installation place: Select environments wisely. Choose areas devoid of corrosive gases and noticeable dirt for optimal transformer operation.

 

Maintenance and upkeep: Ensuring longevity.
Regular inspection: Key to peak performance. Frequent checks of oil level and oil insulation strength tests are vital. Timely replacement of transformer oil upon detecting anomalies ensures uninterrupted function.
Stable operation: Maintain seamless performance. Ensure transformers operate smoothly by preventing overloads and mitigating short circuit risks.
Safety attention: Prioritize protection. Consider plant ventilation, fire prevention, and adhere to technical specifications for correct installation.
