Oil-immersed Transformers Product Details:
Oil-immersed transformers stand out as essential power equipment in electrical systems, adept at efficiently managing voltage conversion and power transmission. Crafted to cater to high current and large capacity requirements, these transformers promise unmatched stability and reliability for modern power networks.

Performance Characteristics:

1. Winding structure:
Our high-voltage winding features a sophisticated multi-layer cylindrical, continuous, or connecting continuous structure. This design innovation significantly enhances the winding's shock distribution, minimizes magnetic leakage, and ensures superior mechanical strength and formidable short-circuit resilience.

2. Iron core design:
Employing premium cold rolled grain-oriented silicon steel sheets with a comprehensive diagonal seam stacking technique, we dramatically reduce no-load loss and optimize no-load current efficiency.

3. Fastening and anti-loosening:
The transformer's core and windings are securely fastened with state-of-the-art measures. High and low voltage body leads feature self-locking anti-loosening nuts, ensuring the structure withstands transportation vibrations. All fasteners are equipped with locking nuts to maintain steadfast integrity during prolonged operation.

4. Vacuum processing:
Through vacuum drying techniques for coils and cores, alongside vacuum filtering and injection of transformer oil, we significantly curtail moisture presence inside the transformer.

5. Oil tank design:
Our oil tank, composed of corrugated sheets with breathing capability, adeptly accommodates oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet diminishes the transformer's overall height.

6. Other features:
Designed with a sleek aesthetic, compact form, and minimal installation footprint, this transformer is the ultimate maintenance-free solution for your energy needs.
Our transformers find extensive application in power plants, substations, industrial and mining enterprises, and rural power grids, forming a vital link in the power distribution network.

 

Environment and Requirements:
Ambient temperature: Typically, the ambient temperature requirement ranges from -25°C to +40°C.
Altitude limit: Positioned at altitudes not exceeding 1000m.
Air humidity: Humidity should remain below 90% relative at a temperature of +25ºC.
Installation place: Choose installation sites devoid of corrosive gases and prominent dirt buildup.

 

Maintenance and upkeep:
Regular inspection: It's imperative to routinely inspect oil levels and conduct oil insulation strength tests. Address any issues promptly by replacing transformer oil as needed.
Stable operation: Guaranteeing the transformer's stable operation involves safeguarding against overloads, short circuits, and other potential anomalies.
Safety attention: Prior to installation, meticulously assess the plant's ventilation and fire precaution measures, adhering strictly to technical specifications for optimal installation.
