In-Depth Oil-Immersed Transformers Product Details:
Oil-immersed transformers are crucial power equipment widely embraced across power systems, excelling in voltage conversion and power transmission. Meticulously crafted for high current and large capacity demands, these transformers deliver unrivaled stability and reliability.

 

Comprehensive Model Meaning:

 

Outstanding Performance Characteristics:

1. Advanced Winding Structure:
Our high-voltage winding utilizes a multi-layer cylindrical, continuous, or connecting continuous structure. This enhances shock distribution, minimizes magnetic leakage, and ensures remarkable mechanical strength and superior short-circuit resistance.

2. Superior Iron Core Design:
Utilizing high-quality cold rolled grain-oriented silicon steel sheets and employing a full diagonal seam stacking method, we effectively reduce no-load loss and no-load current.

3. Firm Fastening and Anti-Loosening Measures:
Each core and winding is secured with dedicated fastening measures. High and low voltage body leads feature self-locking anti-loosening nuts and a non-hanging center structure, allowing them to withstand transit vibrations. Every fastener is equipped with nuts to ensure they remain secured during long-term operation.

4. Advanced Vacuum Processing:
Coils and cores undergo vacuum drying, while transformer oil is meticulously vacuum filtered and injected, significantly reducing moisture content within the transformer.

5. Innovative Oil Tank Design:
Our oil tank, crafted from corrugated sheets with a breathing function, compensates for oil volume changes due to temperature variations. The absence of an oil storage cabinet allows for a reduced transformer height.

6. Additional Exceptional Features:
Boasting a stunning appearance, compact size, and minimal installation footprint, this product is the epitome of maintenance-free excellence.
Versatility in Application: Perfectly suited for power plants, substations, industrial, mining enterprises, and rural power grids, ensuring seamless performance in power distribution systems.

 

Optimal Environment and Requirements:
Ambient Temperature Parameters: Typically maintained between -25°C and +40°C for optimal performance.
Defined Altitude Limit: Should not exceed 1000m for efficient operation.
Air Humidity Constraints: Not exceeding 90% relative humidity at +25ºC.
Ideal Installation Location: Should be free from corrosive gases and obvious dirt for optimum safety and efficiency.

 

Maintenance and Upkeep Guidelines:
Regular Inspection Protocols: Frequent checks of the oil level and oil insulation strength are essential. Should any issues be detected, timely replacement of transformer oil is critical.
Ensuring Stable Operation: Maintain stable transformer operation by avoiding overloads, short circuits, and other irregularities.
Safety Precautions: Prioritize plant ventilation and fire prevention in compliance with technical specifications for accurate and safe installation.
