Divided into S9 and S11, S13 series oil-immersed distribution transformer loss performance, compared with the S11 series transformer no-load loss is 20% lower than the S9 series, S13 series transformer no-load loss is 25% lower than the S11 series. State Grid Corporation has been widely used S11 series distribution transformer, and the Urban Network in the gradual promotion of S13 series, the next period of time of S11, S13, Series oil-immersed distribution transformers will completely replace the existing network running S9 series. 

 Although the distribution transformer industry in China is highly competitive, but with new technology, new materials, new processes of production enterprises, the opportunities outweigh the challenges. Industry in the promotion of national industrial policies and energy-saving smaller, weak corporate R & D capabilities will be phased out, with energy-saving, low noise, intelligent power distribution transformer product development and production capacity of enterprises will further expand market share, future market prospects. 

 Amorphous alloy transformer 

 Amorphous alloy transformer both energy saving and economy, its notable features is a low no-load loss, only about 20% of the S9 series oil-immersed transformer, in line with national industrial policy and the requirements of grid energy saving is energy-saving effect of better distribution transformers, especially for rural power grid and the load rate lower. Although the National Development and Reform Commission in 2005 began to encourage and promote the amorphous alloy transformer, but subject to raw materials, amorphous alloy with the material production capacity constraints, our amorphous alloy transformer has been no large-scale production. 

 Amorphous alloy transformer is currently running in the network accounts for only 7% -8% of total distribution transformers, Shanghai, Jiangsu, Zhejiang and other areas across the country, only large quantities of amorphous alloy transformer. With Advanced Technology amorphous alloy strip production line of production, raw material constraints the problem is resolved, the next 5-10 years, the amorphous alloy transformer in the country to promote the use of the market potential is huge.
