Product Description

Overview
S11-M series fully sealed distribution transformers are suitable for residential areas, commercial centers, high-rise buildings, remote mountainous areas, more dust, more dirty places. It has high technical content, good energy saving effect and great popularization and application value. The performance indicators of this series of products are the relevant national standards, the product structure design is reasonable, the operation reliability is high, the energy saving effect is obvious, the overload capacity is strong, and the noise is low. Compared with S9 type transformer, the no-load loss is reduced by 30 ~ 50% on average, and the no-load current is reduced by 80 ~ 90%. This series of products are made of 08 aluminum cold plate corrugated tank, small volume, compact structure, beautiful appearance. The insulating oil in the oil tank is completely isolated from the outside air, which effectively prevents the oil from being affected with moisture and aging. Under normal conditions of use, it is free of maintenance and maintenance for 20 years, which greatly reduces the operating cost of the product.
