Oil-immersed Transformers Product Details: Unveiling the core of power transformation technology.
Oil-immersed transformers are quintessential power equipment, extensively utilized in power systems for seamless voltage conversion and robust power transmission. Engineered to meet high current and large capacity transformer requirements, they deliver unparalleled stability and reliability in power systems.

 

Model Meaning: Decoding the essence of our transformer designations.

 

Performance Characteristics: Elevating your power solutions with cutting-edge features.

1. Winding structure: Unmatched engineering for supreme efficiency and resilience.
The high-voltage winding is expertly crafted using a multi-layer cylindrical, continuous, or connecting continuous structure. This innovation enhances shock distribution, minimizes magnetic leakage, and offers formidable mechanical strength and superior short-circuit resistance.

2. Iron core design: Precision in design to maximize performance.
Utilizing premium cold rolled grain-oriented silicon steel sheets with a meticulous full diagonal seam stacking method, this design significantly reduces no-load loss and current, ensuring efficiency.

3. Fastening and anti-loosening: Assurance in construction for lasting durability.
The core and windings are securely anchored with robust fastening solutions. High and low voltage leads feature self-locking anti-loosening nuts and a non-hanging center structure, enhancing their ability to endure transportation vibrations. Each fastener is equipped with secure nuts to ensure steadfast operation over time.

4. Vacuum processing: Advanced techniques for superior quality.
Coils and cores undergo meticulous vacuum drying, with transformer oil being vacuum filtered and injected, effectively minimizing moisture content within the transformer.

5. Oil tank design: Ingenious solutions for adaptability and efficiency.
The oil tank features a corrugated sheet design with breathing capabilities to accommodate oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and consequently reducing transformer height.

6. Other features: Compact and stylish, made for modern power systems.
Our transformers boast a beautiful appearance, compact size, and minimal installation footprint, making them the ideal maintenance-free solution for today's power distribution needs.
These transformers are vital components in power plants, substations, industrial and mining enterprises, and rural power grids, serving as the backbone of power distribution systems.

 

Environment and Requirements: Tailored for optimal performance in diverse conditions.
Ambient temperature: Crafting solutions for varied climates. Typically suitable for environments with temperatures ranging from -25°C to +40°C, ensuring adaptability across regions.
Altitude limit: Operating parameters defined for efficiency. Our transformers are engineered to perform flawlessly at altitudes not exceeding 1000m.
Air humidity: Designed to withstand challenging atmospheric conditions. Operate efficiently with air humidity levels not exceeding 90% relative humidity at +25ºC.
Installation place: Selecting optimal settings for enhanced longevity. Choose locations devoid of corrosive gases and noticeable dirt for optimal installation and operation.

 

Maintenance and upkeep: Ensuring longevity through meticulous care.
Regular inspection: Proactive measures for enduring excellence. Regularly assess oil levels and conduct oil insulation strength tests. If discrepancies arise, promptly replace transformer oil to maintain peak performance.
Stable operation: Prioritizing consistent performance. To ensure continuous transformer operation, it is crucial to prevent overloads and short circuits, upholding operational integrity.
Safety attention: Safeguarding installation and operational protocols. Before installation, meticulously consider ventilation and fire prevention measures in compliance with technical specifications to ensure flawless installation.
