Comprehensive Oil-immersed Transformers Product Details:
Oil-immersed transformers represent a pinnacle in power equipment engineering, extensively utilized across power systems for seamless voltage conversion and transmission. These transformers are meticulously crafted to address high current and large capacity requirements in power systems, ensuring unmatched stability and unwavering reliability.

 

Understanding Model Specifications:

 

Key Performance Characteristics:

1. Advanced Winding Structure:
The high-voltage winding features a multi-layer cylindrical, continuous or connecting continuous structure, enhancing shock distribution, minimizing magnetic leakage, and offering superior mechanical strength with robust short-circuit resistance.

2. Innovative Iron Core Design:
Utilizing high-quality, cold-rolled grain oriented silicon steel with an expertly crafted full diagonal seam stacking method, the design is engineered to reduce both no-load loss and no-load current.

3. Enhanced Fastening and Anti-loosening Capabilities:
Both the core and windings are secured with reliable fastening measures, including self-locking anti-loosening nuts on high and low voltage leads, with a non-hanging center structure to withstand transportation vibrations. All fastening components are reinforced with nuts to prevent loosening over long-term operations.

4. State-of-the-Art Vacuum Processing:
Coils and cores undergo vacuum drying, while transformer oil is vacuum filtered and injected meticulously, ensuring minimal moisture presence within the transformer.

5. Innovative Oil Tank Design:
Featuring a corrugated sheet with a breathing function, the oil tank adeptly compensates for oil volume fluctuations due to temperature changes, eliminating the need for an oil storage cabinet and consequently reducing the transformer's height.

6. Additional Features that Stand Out:
With a beautiful appearance and compact size, it requires minimal installation space and is the perfect maintenance-free solution.
Widely implemented in power plants, substations, industrial ventures, mining operations, and rural power grids within power distribution systems.

 

Operating Environment and Essential Requirements:
Optimal Ambient Temperature: Typically maintained between -25°C and +40°C.
Maximum Altitude Limit: Should not exceed 1000m for optimal performance.
Maximum Air Humidity: Should not exceed 90% relative humidity (at +25ºC).
Choosing the Right Installation Place: Select an area devoid of corrosive gases and significant dirt for installation.

 

Comprehensive Maintenance and Upkeep Guidelines:
Regular Inspection and Maintenance: Periodic checks on oil level and oil insulation strength are necessary. Prompt transformer oil replacement is required if issues are detected.
Ensuring Stable Operation: To maintain stable transformer operation, it is crucial to prevent overloads, short circuits, and other operational anomalies.
Critical Safety Considerations: Prior to installation, address ventilation and fire prevention, ensuring adherence to technical specifications for correct setup.
