In-Depth Oil-immersed Transformers Product Details:
Oil-immersed transformers stand as an essential powerhouse in modern power systems, adeptly handling voltage conversion and power transmission. Crafted to meet the high current and large capacity demands of power systems, these transformers are synonymous with unparalleled stability and reliability.

 

Understanding the Model Meaning:

 

Explore the Performance Characteristics:

1. Innovative Winding Structure:
Our high-voltage winding employs a multi-layer cylindrical, continuous, or connecting continuous structure, enhancing shock distribution, reducing magnetic leakage, and offering high mechanical strength with robust short-circuit resistance.

2. Advanced Iron Core Design:
Using superior cold rolled grain-oriented silicon steel sheets and a full diagonal seam stacking method, we significantly alleviate no-load loss and minimize no-load current.

3. Secure Fastening and Anti-Loosening:
With specialized fastening solutions, each core and winding is secured. High and low voltage leads are equipped with self-locking anti-loosening nuts, utilizing a non-hanging center structure to endure transportation vibrations. All fasteners feature locking nuts to ensure long-term stability.

4. State-of-the-Art Vacuum Processing:
Our coils and cores undergo meticulous vacuum drying, while transformer oil is filtered and injected in a vacuum, effectively minimizing internal moisture.

5. Innovative Oil Tank Design:
Our oil tank, designed with corrugated sheets featuring a breathing function, compensates for oil volume changes due to temperature variations, eliminating the need for an oil storage cabinet and reducing the transformer's height.

6. Additional Features to Admire:
With a sleek appearance, compact volume, and minimal installation space requirements, this transformer is the quintessential maintenance-free product.
Ideally suited for use in power plants, substations, industrial and mining enterprises, as well as rural power grids within power distribution systems.

 

Environment and Requirements for Optimal Functioning:
Ambient Temperature Guidelines: Designed to function optimally between -25°C and +40°C.
Altitude Limitations: Optimized for installation at altitudes not exceeding 1000 meters.
Air Humidity Considerations: Requires a maximum of 90% relative humidity at a temperature of +25ºC.
Ideal Installation Locations: Choose an area free from corrosive gases and significant dirt for installation.

 

Maintenance and Upkeep to Ensure Longevity:
Regular Inspection Regimen: Conduct frequent checks on oil levels and test oil insulation strength. Promptly replace transformer oil if issues are detected.
Ensuring Stable Operation: Maintain steady transformer operation by preventing overloads, short circuits, and other irregularities.
Safety Considerations and Precautions: Prioritize ventilation and fire prevention during installation. Ensure adherence to technical specifications for accurate installation.
