Oil-immersed Transformers Product Details:
Our oil-immersed transformers stand as a pivotal component in power systems, expertly tailored for voltage conversion and seamless power transmission. Engineered to meet the rigorous demands for high current and large capacity, this transformer ensures unmatched stability and reliability for all your power system needs.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding boasts a sophisticated multi-layer cylindrical, continuous, or connecting continuous structure, enhancing shock distribution. With minimal magnetic leakage, exceptional mechanical strength, and robust short-circuit resistance, our design excels in performance and durability.

2. Iron core design:
Utilizing premium cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, we significantly reduce no-load loss and no-load current, optimizing efficiency and performance.

3. Fastening and anti-loosening:
Ingenious fastening methods secure the core and windings, while self-locking anti-loosening nuts on all high and low voltage leads ensure stability. Adopting a non-hanging center structure, it can withstand transportation vibrations. All fasteners are equipped with secure nuts, ensuring long-term operation without loosening.

4. Vacuum processing:
Our advanced vacuum drying process for coils and cores, combined with vacuum-filtered and injected transformer oil, effectively minimizes moisture, safeguarding transformer efficiency and longevity.

5. Oil tank design:
The oil tank features a corrugated sheet with dynamic breathing capability to accommodate oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing the transformer's overall height.

6. Other features:
With its striking appearance, compact size, and minimal installation footprint, this transformer is the epitome of maintenance-free convenience, perfectly suited for modern power systems.
Versatile and widely applicable, our transformers serve power plants, substations, industrial and mining enterprises, as well as rural power grids, providing a reliable backbone for power distribution systems.

 

Environment and Requirements:
Ambient temperature: Optimally required to range between -25°C and +40°C.
Altitude limit: Should not exceed 1000m.
Air humidity: Must remain below 90% relative humidity (at +25ºC) for optimal performance.
Installation place: Select an installation area devoid of corrosive gases and without significant contaminants for best results.

 

Maintenance and upkeep:
Regular inspection: Frequent inspection of oil levels and testing of oil insulation strength is vital. Prompt replacement of transformer oil is required if issues are identified.
Stable operation: Ensuring stable operation is crucial; avoid overload and short-circuit scenarios to maintain optimal functionality and safety.
Safety attention: Prior to installation, address ventilation and fire prevention concerns, adhering strictly to technical specifications for precise and safe installation.
