Unveiling the Oil-immersed Transformers: Detailed Product Insights
Oil-immersed transformers play a crucial role in power systems globally, primarily facilitating seamless voltage conversion and efficient power transmission. Engineered to meet high current and substantial capacity demands, these transformers promise unmatched stability and reliability in power systems.

 

Understanding the Model Significance:

 

Distinctive Performance Characteristics:

1. Innovative Winding Structure:
Our high-voltage winding utilizes a sophisticated multi-layer cylindrical, continuous, or connecting continuous structure, enhancing shock distribution, minimizing magnetic leakage, and providing superior mechanical strength and short-circuit resilience.

2. Advanced Iron Core Design:
The use of premium cold-rolled grain-oriented silicon steel sheets, coupled with a full diagonal seam stacking technique, significantly decreases no-load loss and no-load current, maximizing efficiency.

3. Secure Fastening and Anti-loosening Innovations:
Robust fastening measures secure the core and windings, while self-locking anti-loosening nuts on high/low voltage leads prevent detachment. An innovative non-hanging center structure withstands transportation vibrations, ensuring longevity and operational integrity.

4. Precision Vacuum Processing:
Our vacuum drying of coils and cores, along with vacuum-filtered and injected transformer oil, effectively reduces moisture, safeguarding the transformer's internal components.

5. Ingenious Oil Tank Design:
Featuring corrugated sheets with inherent breathing capabilities, our oil tank adeptly compensates for oil volume changes due to temperature fluctuations, eliminating the need for a bulky oil storage cabinet and reducing transformer height.

6. Additional Noteworthy Features:
Aesthetic design and compact size make these transformers ideal for installations with limited space. As maintenance-free products, they stand as a perfect solution for modern applications.
Ideally employed in power plants, substations, industrial and mining enterprises, and rural power grids, these transformers excel in diverse power distribution systems.

 

Environmental Conditions and Requirements:
Optimal Ambient Temperature: Typically maintained between -25°C and +40°C for optimal performance.
Maximum Altitude Limit: Installation should not exceed an altitude of 1000 meters.
Air Humidity Constraints: Relative humidity must not exceed 90% at a temperature of +25ºC.
Recommended Installation Location: Select a site devoid of corrosive gases and significant dirt accumulation to ensure longevity and performance.

 

Comprehensive Maintenance and Upkeep:
Routine Inspections: Regularly monitor oil levels and conduct insulation strength tests. Prompt replacement of transformer oil is recommended upon detection of issues.
Ensure Stable Operation: Maintain consistent operational conditions to prevent overload, short circuits, and other anomalies, ensuring the transformer's reliability.
Critical Safety Considerations: Prior to installation, evaluate plant ventilation and fire hazards. Adhere to technical guidelines for safe and correct installation.
