Oil-immersed Transformers Product Details:
Our oil-immersed transformers stand as a quintessential element in power systems, adeptly facilitating voltage conversion and power transmission with unmatched efficiency. Tailored for high-current, large-capacity needs, these transformers epitomize high stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Employing a high-voltage winding with a multi-layer cylindrical, continuous, or connecting continuous design, this structure enhances shock distribution, minimizes magnetic leakage, and boasts impressive mechanical strength and robust short-circuit resistance.

2. Iron core design:
Utilizing premium cold-rolled, grain-oriented silicon steel sheets with a full diagonal seam stacking method, this design significantly reduces both no-load loss and current.

3. Fastening and anti-loosening:
Strategically fastened core and windings, complemented by self-locking anti-loosening nuts on high and low voltage leads, enable the entire structure to withstand transport vibrations. Fasteners are meticulously fitted with nuts to guarantee steadfast security throughout prolonged operation.

4. Vacuum processing:
Advanced vacuum drying of coils and cores, coupled with vacuum-filtered transformer oil injection, ensures minimal internal moisture, optimizing transformer performance.

5. Oil tank design:
Our thoughtfully engineered oil tank, crafted from corrugated sheets with a breathing function, adapts to oil volume changes from temperature fluctuations, negating the need for an oil storage cabinet and thus reducing the transformer's height.

6. Other features:
Exuding a strikingly beautiful appearance, compact size, and minimal installation footprint, these maintenance-free transformers are the ultimate choice for efficiency and elegance.
They find extensive application in power plants, substations, industrial and mining enterprises, and rural power grids, serving as a cornerstone in power distribution systems.

 

Environment and Requirements:
Ambient temperature: Optimal operation is generally within the temperature range of -25°C to +40°C.
Altitude limit: Designed for locations not exceeding an altitude of 1000m.
Air humidity: Maintains performance in environments with up to 90% relative humidity at 25ºC.
Installation place: Select an installation site free from corrosive gases and conspicuous dirt for optimal longevity.

 

Maintenance and Upkeep:
Regular inspection: Frequent checks of oil levels and oil insulation strength are crucial. Promptly replace transformer oil if any issues arise.
Stable operation: Ensuring stable transformer operation involves preventing overloading, short circuits, and other anomalies.
Safety attention: Before installation, consider plant ventilation and fire prevention, following technical specifications for correct setup.
