Future Development Trend of Distribution Transformer Industry

At present, some high power loss distribution transformers in the grid are not in line with the development trend of the industry, facing the need of technology upgrading. and will be replaced by energy saving, material saving, environmental protection and low noise transformers.
In 2008, 2009, China's power grid construction investment are more than that of power supply construction, suggesting that China's power grid construction problems will be improved. To achieve the balance of power supply and power grid, China still need to improve the power transmission and distribution capacity to match power supply. In the next few years, power grid construction and urban and rural distribution network transformation is still the primary task of China's power industry, distribution transformer market demand is expected to maintain a relatively strong increase.

Energy - saving oil - immersed transformers
The oil-immersed distribution transformers are divided into S9, S11 and S13 series according to the loss performance. In contrast, the no-load loss of the S11 series transformer is 20% lower than that of the S9 series, and the no-load loss of the S13 series transformer is 25% lower than that of the S11 series. At present, S11 series distribution transformers have been widely used by State Grid Corporation of China, and S13 series are being gradually promoted in the transformation of urban network. In the future, S11 and S13 series oil-immersed distribution transformers will completely replace the existing S9 series.
Although China's distribution transformer industry is highly competitive, with new technologies, new materials, new technology, the chance of the enterprise is greater than the challenge. Driven by the national industrial policy and "energy saving", the industry's enterprises with smaller, less research and development capabilities will be eliminated, those with energy-saving, low noise, intelligent distribution transformer product development and production capacity will further expand the market share.

Amorphous alloy transformer
Amorphous alloy transformer with energy-saving and economic characteristics, notable feature is very low no-load loss, only about 20% of S9 series oil-immersed transformers, in line with national industrial policies and energy-saving power grid requirements, is the ideal energy-saving distribution transformer, especially suitable for rural power grids and other low-load areas. Although as early as 2005, the National Development and Reform Commission to encourage and promote amorphous alloy transformers, subject to raw materials, i.e. amorphous alloy strip production capacity constraints, China's amorphous alloy transformer has not been large-scale production. Currently running in the grid, amorphous alloy transformers account for only 7% -8% of the proportion of distribution transformers, the country only in Shanghai, Jiangsu, Zhejiang and other regions using large quantities of amorphous alloy transformers. With the amorphous alloy strip production line of Aetna technology, raw material problems can be resolved, in the next 5-10 years, amorphous alloy transformers will be widely used throughout the country, the market has great potential.
