In-depth Oil-immersed Transformers Product Details:
Oil-immersed transformers are indispensable power equipment extensively utilized across power systems. They primarily serve the crucial functions of voltage conversion and power transmission. Engineered to meet the high current and large capacity demands, these transformers offer unparalleled stability and reliability within the power system.

 

Model Meaning:

 

Exemplary Performance Characteristics:

1. Innovative Winding Structure:
Our high-voltage winding employs a sophisticated multi-layer cylindrical structure, with continuous or connecting continuous designs. This enhances the shock distribution, minimizes magnetic leakage, ensures high mechanical strength, and delivers robust short-circuit resistance.

2. Advanced Iron Core Design:
Utilizing premium cold rolled grain-oriented silicon steel with a full diagonal seam stacking method, our design significantly reduces both no-load loss and no-load current, optimizing your energy efficiency.

3. Superior Fastening and Anti-loosening Features:
Every core and winding is securely fastened, with high and low voltage leads reinforced by self-locking anti-loosening nuts. The non-hanging center design withstands transportation vibrations. All fasteners feature locking nuts to prevent loosening during extended operations.

4. Precision Vacuum Processing:
Both coils and cores undergo meticulous vacuum drying, and transformer oil is carefully vacuum-filtered and injected. This process significantly reduces internal moisture content, enhancing transformer longevity.

5. Innovative Oil Tank Design:
Our oil tank features a corrugated sheet with a unique breathing function, accommodating oil volume changes due to temperature fluctuations. This eliminates the need for an oil storage cabinet, thereby reducing the transformer's height.

6. Distinctive Features:
Boasting an aesthetically pleasing design, compact size, and minimal installation space, these transformers are the ultimate maintenance-free solution.
Perfectly suited for deployment in power plants, substations, industrial and mining sectors, as well as rural power grids, enhancing your power distribution system.

 

Environment and Requirements:
Recommended Ambient Temperature: typically ranges from -25°C to +40°C, ensuring optimal performance.
Recommended Altitude Limit: should not exceed 1000 meters, maintaining performance integrity.
Humidity Specifications: relative humidity must not surpass 90% at a temperature of +25ºC, to ensure proper function.
Ideal Installation Location: Select an environment devoid of corrosive gases and visible contaminants to preserve equipment integrity.

 

Maintenance and Upkeep Guidelines:
Rigorous Regular Inspection: Consistently monitor oil levels and conduct oil insulation strength tests. Promptly replace transformer oil if issues are detected.
Ensuring Stable Operation: Maintain a stable operational environment by preventing overloads, short circuits, and other potential anomalies.
Safety Precautions: Prioritize ventilation and fire prevention during installation, adhering strictly to technical specifications for safe setup.
