Product Description

Parameters

S11 35kV DUAL- WINDING NON- EXCITATION REGULATING TRANSFORMER

Summary

S11 series oil-immersed transformer adopts traditional compact structure with high reliability. This series of product adopts fully sealed oil tank, thus isolating the transformer oil from the air and slowing down the aging of transformer oil and insulators. This series of product uses traditional material and is efficient and energy-saving. The product has been widely applied in new and reconstruction projects of urban and rural power grids such as Hydropower station and Power plant.
