Oil-immersed Transformers Product Details: Discover the epitome of efficiency and robustness.
Oil-immersed transformers are indispensable power equipment extensively utilized within power systems. They primarily serve the critical roles of voltage conversion and power transmission, designed specifically to meet the high current and large capacity demands of power systems. These transformers are crafted for unparalleled stability and reliability.

 

Model Meaning: Deciphering the significance behind each meticulous design.

 

Performance Characteristics: A testament to advanced engineering and innovation.

1. Winding Structure: Ingenious engineering for superior performance.
The high-voltage winding features a multi-layer cylindrical design, employing continuous or connecting continuous structures. This design enhances shock distribution and minimizes magnetic leakage, offering impressive mechanical strength and robust short-circuit resistance.

2. Iron Core Design: Optimized for efficiency and reduced energy loss.
Utilizing premium cold rolled grain-oriented silicon steel sheets, along with a full diagonal seam stacking method, ensures reduced no-load loss and minimized no-load current, enhancing overall transformer efficiency.

3. Fastening and Anti-loosening: Securing components for lasting durability.
The core and windings are meticulously fastened with advanced measures. High and low voltage leads, equipped with self-locking anti-loosening nuts, utilize a non-hanging center structure to withstand transportation vibrations. All fasteners are secured with locking nuts, guaranteeing steadfastness during prolonged operation.

4. Vacuum Processing: Ensuring purity and longevity.
Through vacuum drying of coils and cores, alongside vacuum filtering and injection of transformer oil, our process ensures minimal moisture presence within the transformer, promoting extended operational life.

5. Oil Tank Design: Adaptable and efficient.
Our oil tank, crafted from corrugated sheets with a breathing function, accommodates oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's overall height, streamlining design without compromising functionality.

6. Other Features: Compact, versatile, and maintenance-free.
Aesthetically pleasing with a compact build, our transformers require minimal installation space and epitomize ideal maintenance-free solutions.
This transformative technology is widely employed in power plants, substations, industrial and mining sectors, and rural power grids, enhancing the power distribution system's efficacy.

 

Environment and Requirements: Setting the stage for optimal performance.
Ambient Temperature: Tailored for varying climates. Operational within a broad range from -25°C to +40°C, ensuring adaptability across diverse environmental conditions.
Altitude Limit: Performance beyond limits. Engineered to perform optimally at altitudes not exceeding 1000m.
Air Humidity: Preserving integrity in humidity. Designed to function seamlessly in environments with a relative humidity level not exceeding 90% at +25ºC.
Installation Place: Prerequisites for placement. Select areas devoid of corrosive gases or conspicuous dirt to ensure the transformer's longevity and performance.

 

Maintenance and Upkeep: Sustaining excellence over time.
Regular Inspection: Vigilance for longevity. Conduct frequent checks on oil levels and oil insulation strength. Prompt replacements are necessary if issues arise, ensuring uninterrupted functionality.
Stable Operation: Keeping the flow consistent. To maintain seamless operation, avoid overloads and prevent short circuits by adhering to recommended usage protocols.
Safety Attention: Preparation for safe installation. Prioritize ventilation and fire prevention during installation. Adhere to all technical specifications for secure setup.
