Oil Immersed Transformer S11 Series

S11 oil-immersed power transformer is used for transformer equipment, S-11-M series fully sealed oil-immersed power transformer has the advantages of low loss, low noise, high efficiency, can achieve good energy saving effect and reduce pollution.

Low Loss and Low Noise: The S11 transformer uses imported high-quality cold-rolled silicon steel sheets stacked into the core, significantly reducing no-load loss and no-load current. At the same time, the core's tightness is ensured through the use of ties, further reducing noise. Additionally, the seamless design of the S11 transformer's core further reduces no-load loss and current, decreasing no-load current by 60% to 80% and noise by more than 10 dB.

High Efficiency and Long Life: The high-voltage winding of the S11 transformer adopts a multi-layer cylindrical structure, while the low-voltage winding uses a double-layer cylindrical structure for units up to 500 KVA. For units of 630 KVA and above, a double-helix or quadruple-helix structure is used to improve transformer efficiency and performance. The oil tank of the transformer is fully sealed, which prolongs service life and eliminates the need for core lifting and maintenance.

High Reliability and Safety: The linkage group of the S11 transformer adopts the Dyn11 connection, reducing the impact of harmonics on the power grid and improving power supply quality. The fully sealed structure not only extends service life but also enhances operational reliability. Furthermore, the manufacturing process of the S11 transformer involves strict steps in design, material preparation, core and winding manufacturing, ensuring product quality and safety.

Compact Structure and Attractive Appearance: The oil tank of the S11 transformer features a corrugated plate radiator. When the oil temperature changes, the thermal expansion and contraction of the corrugated plates replace the function of the oil storage cabinet. This design not only saves space but also improves the aesthetic appearance.

Wide Range of Applications: The S11 transformer is widely used in electric power systems, industrial production, and construction fields. In the power system, it is used for power transmission, distribution, and substations, converting high-voltage electrical energy into low-voltage electrical energy. In industrial production, it provides a stable power supply for various industrial equipment and production lines. In urban construction, it ensures reliable power supply for urban power grids and buildings.
