1. Product introduction
The 35 kV series oil-immersed power transformers are the ultimate energy-efficient transformers for 35 kV voltage levels. Featuring high-quality silicon steel sheets, a fully sealed design, and proven manufacturing processes, these transformers exhibit lower losses, reduced noise levels, and increased operational stability compared to the S9 and S10 series models. Primarily designed for 35 kV transmission and distribution systems, they perform voltage transformation and power distribution while delivering energy efficiency, reliability, maintenance-free operation, and an extended service life. Widely used in utility power, industrial/mining applications, infrastructure projects, and the renewable energy sector, they are currently the most common energy-saving solution in 35 kV distribution systems.

3. Key Features
1. Energy-efficient design with low operating costs: Significantly reduced no-load losses compared to S10 models, delivering outstanding energy efficiency performance. Long-term operation ensures energy savings and rapid return on investment, fully complying with national energy saving standards.
Low noise operation: The iron core adopts optimized magnetic circuit design and multi-stage connection technology, which ensures minimal vibration and low noise, making it suitable for quiet places such as residential areas, schools and hospitals.
Fully sealed, maintenance-free design with oil-free bearings: The fully sealed design prevents the insulation oil from coming into contact with air, reducing oxidation and moisture absorption. This eliminates core suspension and frequent maintenance, reducing operating and maintenance costs.
Strong short-circuit resistance, high mechanical strength of the winding, reliable insulation that can withstand power grid surges, load fluctuations and short circuits, ensuring safe and stable operation.
High reliability and long service life with rational heat dissipation system, corrosion and weather resistant properties, rugged overall design and service life of more than 20 years.
Highly adaptable and easy to install, suitable for indoor and outdoor applications, as well as transformer substations and power conversion stations, able to work in various conditions, including high altitude areas, humid conditions, dusty conditions and coastal areas.
