Oil-immersed Transformers Product Details: Dive into the technical prowess and design excellence of our transformers, crafted for unparalleled performance.
Oil-immersed transformers are a premier category of power equipment extensively deployed across power systems. They excel in voltage conversion and power transmission, specifically tailored to meet the demands of high current and substantial capacity within power networks. Renowned for their exceptional stability and unwavering reliability, they stand as a testament to engineering excellence.

 

Model Meaning: A comprehensive insight into the naming conventions and model specifications that define our transformers.

 

Performance Characteristics: Discover the key attributes and unique features that set our transformers apart in the industry.

1. Winding structure: An innovative design focusing on enhanced stability and performance for optimal electrical distribution.
The high-voltage winding employs a multi-layer cylindrical, continuous or connecting continuous structure. This sophisticated design enhances shock distribution within the winding, minimizes magnetic leakage, and ensures superior mechanical strength. It offers remarkable resilience against short-circuit conditions.

2. Iron core design: Exemplifying cutting-edge engineering for reduced power loss and enhanced transformer efficiency.
Our transformers feature iron cores made from high-quality, cold-rolled, grain-oriented silicon steel sheets. The diagonal seam stacking method significantly curtails no-load loss and minimizes no-load current, ensuring efficient operation.

3. Fastening and anti-loosening: Precision engineering for stability and endurance during transport and operation.
Each core and its windings are securely fastened with precision-engineered measures. High and low voltage leads are equipped with self-locking anti-loosening nuts, complemented by a non-hanging center structure to withstand transportation vibrations. Every fastener is fitted with durable nuts to ensure operational stability over time.

4. Vacuum processing: Advanced techniques for optimal transformer condition and longevity.
Coils and cores are meticulously vacuum-dried, while the transformer oil undergoes thorough vacuum filtering and injection. This process minimizes moisture content, ensuring the transformer remains in peak condition.

5. Oil tank design: Smart engineering for compact size and environmental resilience.
The oil tank features a corrugated sheet design with a breathing function, catering to oil volume changes due to temperature fluctuations. Its absence of an oil storage cabinet reduces overall transformer height, optimizing space usage.

6. Other features: Compact elegance and reliable performance for diverse settings.
Showcasing a sleek, compact design, these transformers require minimal installation space and are maintenance-free, making them an ideal choice for a variety of applications.
Our transformers are extensively utilized in power plants, substations, industrial operations, mining enterprises, and rural power grids, providing critical support in power distribution systems.

 

Environment and Requirements: Guidelines for optimal transformer placement and operation.
Ambient temperature: The optimal range for transformer performance and longevity. The ambient temperature should ideally range between -25°C and +40°C for optimal transformer performance.
Altitude limit: Ensuring peak efficiency at various heights. Transformers should be installed at altitudes not exceeding 1000 meters to maintain efficient functionality.
Air humidity: Operating conditions for sustained reliability. Relative humidity should not surpass 90% at a temperature of +25ºC to ensure reliable transformer operation.
Installation place: Criteria for selecting the ideal location. Select an installation area free from corrosive gases and noticeable dirt to ensure optimal performance and longevity.

 

Maintenance and upkeep: Essential practices for maintaining transformer health.
Regular inspection: Proactive measures for sustained transformer performance. Conduct frequent checks of the oil level and assess oil insulation strength. Prompt replacement of transformer oil is essential upon detecting any issues.
Stable operation: Safeguarding against operational anomalies. Ensure transformer stability by preventing overloads, short circuits, and other operational anomalies.
Safety attention: Critical considerations for safe installation and operation. Prior to installation, consider plant ventilation and fire prevention, adhering to technical specifications for accurate and safe installation.
