1.High-efficiency core structure

Adopting high permeability grain oriented cold rolled silicon steel sheet, full oblique seam stacking process, the core column is multi-stage stepped circular cross-section, uniform magnetic circuit, low no-load loss.

2. Strong heat dissipation winding process

The winding adopts corrugated oil channel + tight tape tying, non-impregnated paint process, high heat dissipation efficiency; concentric coil design, high-voltage winding is equipped with power-off adjustable tap changer, safe operation.

3. Fully sealed tank system

Corrugated oil tank structure: both heat dissipation and "breathing" compensation function, vacuum oil injection process to eliminate moisture intrusion, no oil storage cabinet design, maintenance-free, anti-oil aging.

Security And Monitoring

1. Multiple safety protection: 30~2500kVA standard with pressure relief valve, optional gas relay (with alarm/trip function).

2. Intelligent temperature control: The whole system is equipped with oil-immersed glass thermometer as standard, and 1000~2000kVA is equipped with outdoor signal thermometer to monitor the oil temperature in real time.

Advantageous Highlights

1. Long life and low maintenance: Fully sealed anti-oxidation design, no need for regular oil sample testing.

2. Compact and reliable: Corrugated tank surface powder coating, corrosion resistance and solid structure.

3. Safety upgrade: Tap changer power-off operation + multiple protection devices to eliminate operational risks.

Transformer Workshop

20kV oil-immersed transformers are high - quality electrical devices with several notable features.

I. Design and Construction

These transformers are engineered with precision. The oil - immersion design serves multiple purposes. The insulating oil not only provides excellent electrical insulation but also aids in heat dissipation. The core is made of high - quality magnetic materials, which ensures efficient magnetic flux transfer and reduces energy losses during the transformation process.

II. Performance Characteristics

1. Voltage Transformation: They are specifically designed to handle 20kV input voltages and transform them to the desired output voltages accurately. This makes them suitable for a variety of industrial and power distribution applications.
2. High Efficiency: Thanks to their advanced design, they can achieve high - efficiency levels. This means less energy is wasted during the transformation, resulting in cost savings and a more environmentally - friendly operation.
3. Reliability: Built with robust materials and strict manufacturing standards, these transformers are highly reliable. They can operate continuously for long periods without significant breakdowns, ensuring a stable power supply.

III. Safety and Maintenance

Safety is a key aspect. The oil - immersed design helps in preventing electrical arcing and overheating. In terms of maintenance, regular checks of the oil level and quality, along with inspections of the electrical connections, can keep the transformer in optimal condition for years. Overall, 20kV oil-immersed transformers are an excellent choice for reliable and efficient power transformation in various electrical systems.
