The 10kV oil-immersed transformer (S13 series and related models) is a fully sealed, high-efficiency power distribution transformer designed for medium-voltage systems. It features low loss, low noise, and strong overload capacity, making it suitable for continuous operation in industrial, utility, and renewable energy environments.

With a capacity range from 30kVA to 2500kVA, this transformer adopts advanced cold-rolled silicon steel cores and oxygen-free copper windings, ensuring high efficiency and long service life. The fully sealed tank design eliminates the oil conservator, reducing maintenance requirements and preventing oil degradation caused by air exposure.

The 13.5kV oil-immersed power transformer is a high-efficiency distribution unit designed for medium-voltage power systems requiring stable and reliable performance. It is widely applied in industrial facilities, utility grids, and renewable energy projects where customized voltage levels such as 13.5kV are required.

Built with premium cold-rolled silicon steel cores and oxygen-free copper windings, this transformer ensures low energy loss, reduced noise, and long-term durability. The fully sealed tank design prevents oil oxidation and moisture ingress, enabling maintenance-free operation and extended service life of over 25 years under normal conditions.

The 35kV oil-immersed on-load tap changing (OLTC) power transformer is designed for modern medium-voltage power systems that require continuous voltage regulation and high operational stability. It is widely used in utility substations, industrial power networks, and renewable energy integration projects.

With a high-capacity range from 3150kVA to 31500kVA, this transformer is engineered using premium silicon steel cores and oxygen-free copper windings. It delivers high efficiency, low energy loss, and strong overload capability, while the OLTC system enables real-time voltage adjustment without interrupting power supply, ensuring stable grid performance under variable load conditions.

The 11kV Dry-Type Voltage Transformer is a precision instrument transformer designed for accurate voltage measurement and protection in medium-voltage systems. Utilizing advanced epoxy resin casting technology, it offers excellent insulation, low partial discharge, and stable performance. It is widely used in indoor switchgear, substations, and industrial power systems requiring reliable voltage monitoring.

The 6kV Dry-Type Voltage Transformer is a compact and high-precision instrument transformer designed for voltage measurement, metering, and protection in medium-voltage systems. Using advanced epoxy resin casting technology, it ensures excellent insulation strength, low partial discharge, and long-term operational stability. It is widely applied in indoor switchgear, substations, and industrial power distribution systems requiring reliable voltage monitoring.

The YB Prefabricated Substation is a compact, factory-integrated power distribution unit that combines high-voltage switchgear, transformer, and low-voltage distribution equipment into a sealed outdoor enclosure. It is designed for fast installation, stable operation, and high safety performance. With flexible capacity and strong environmental resistance, it is widely used in urban grids, industrial parks, and renewable energy projects requiring reliable and efficient power supply.
