Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential components in power systems, expertly crafted for seamless voltage conversion and efficient power transmission. Engineered to meet the stringent demands of high current and large capacity, our transformers offer unmatched stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding utilizes a multi-layer cylindrical structure, designed for superior shock distribution, minimized magnetic leakage, heightened mechanical strength, and exceptional short-circuit resistance.

2. Iron core design:
We employ high-quality cold rolled grain oriented silicon steel sheets with a full diagonal seam stacking method, significantly reducing both no-load loss and no-load current.

3. Fastening and anti-loosening:
Every core and winding is meticulously secured with advanced fastening techniques. Equipped with self-locking anti-loosening nuts, our design ensures resilience against transportation vibrations. All fasteners are reinforced with fastening nuts to maintain stability during prolonged operation.

4. Vacuum processing:
Our manufacturing process includes vacuum drying of coils and cores, paired with vacuum filtering and injection of transformer oil, effectively minimizing internal moisture.

5. Oil tank design:
The oil tank features a corrugated sheet with a breathing function to accommodate volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing overall transformer height.

6. Other features:
With a stunning design, compact size, and minimal installation footprint, our transformers are the quintessential maintenance-free products for modern power systems.
Ideal for deployment in power plants, substations, and industrial sectors, as well as rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to be within a range of -25°C to +40°C.
Altitude limit: Not to exceed an altitude of 1000m.
Air humidity: Should not surpass 90% relative humidity at +25ºC.
Installation place: Choose a site devoid of corrosive gases and significant dirt accumulation.

 

Maintenance and upkeep:
Regular inspection: Consistent monitoring of the oil level and insulation strength is essential. Prompt replacement of transformer oil is necessary upon issue detection.
Stable operation: Ensure the transformer's stable operation by averting overloads, shorts, and other irregularities.
Safety attention: Pre-installation assessments should include plant ventilation, fire safety, and compliance with technical installation standards.
