随着我国经济建设的不断发展，人民生活水平的提高、用电负荷增加、变压器设备增多，带来能源消耗大而且噪声增大，严重污染城市环境，为此世界各国都在呼吁并着手降低能耗、改善城市环境。S13-M 全密封油浸式变压器比当前城网建设用的 S9、S11 型相比，空载损耗分别平均下降 50% 和 30%，噪声水平下降 5~8db。
        With the continuous development of China's economy, the improvement of people's living standards, the increase in electricity load, and the growing number of transformer equipment, energy consumption has risen, and noise pollution has intensified, severely contaminating the urban environment. In response, countries around the world are advocating for and taking steps to reduce energy consumption and improve urban environmental quality. Compared to the S9 and S11 models currently used in urban power grid construction, the S13-M fully sealed oil-immersed transformer reduces no-load losses by an average of 50% and 30%, respectively, and lowers noise levels by 5 to 8 decibels.
