The 220kV Outdoor Oil-Immersed Power Transformer is designed for high-voltage transmission and distribution systems in utility substations, industrial power networks, renewable energy projects, and large-scale infrastructure facilities. Rated from 31,500kVA to 400,000kVA, this transformer delivers stable power transmission, low energy losses, and reliable long-term operation under demanding outdoor conditions.
Built with advanced core materials, optimized winding structures, and efficient oil circulation cooling systems, the transformer ensures excellent voltage regulation, high short-circuit withstand capability, and extended service life. It complies with international standards such as IEC, IEEE, and GB requirements.
The transformer adopts high-grade grain-oriented silicon steel cores with step-lap construction, effectively reducing no-load losses, noise levels, and magnetic flux leakage.
A carefully designed oil-paper insulation structure provides excellent dielectric strength and thermal stability, ensuring safe operation under high-voltage conditions.
Optimized winding arrangements and reinforced clamping structures improve mechanical strength and enhance resistance to short-circuit impacts.
Depending on project requirements, cooling methods such as ONAN, ONAF, OFAF, or OFWF can be provided, ensuring stable temperature rise control during continuous operation.
The transformer tank, radiators, conservator, and accessories are treated with anti-corrosion coatings, making the unit suitable for harsh climates including coastal, desert, tropical, and high-altitude regions.
High-quality insulating oil, vacuum drying technology, and strict manufacturing processes contribute to a service life exceeding 30 years under normal operating conditions.
The transformer mainly consists of:
