Increased investment in distribution network renovation leads to a surge in demand for new energy-saving distribution transformers

State Grid Corporation of China's proposal to increase distribution network automation and rural power grid renovation will directly increase investment in power grid construction, providing strong impetus for the increase in demand for transformers in the market. Han Kejun, Deputy Director of the Product Technology Center of a certain group, said in an interview with reporters that investment in power construction has brought opportunities and challenges to the transformer industry, promoting its rapid development. It is expected that the scale of China's transformer industry will continue to increase during the 13th Five Year Plan period.

This viewpoint coincides with the view of Song Zhichen, an energy industry researcher at China Investment Consulting. In Song Zhichen's view, the focus and development strategy of State Grid Corporation of China have a significant impact on the entire power industry. The implementation of distribution network automation and rural network transformation work will drive the rapid development of the power transformation and distribution field, especially the total demand and bidding quantity of the transformer market will greatly increase. The global transformer market will gradually tilt towards China, and the application of cutting-edge products is expected to achieve better results in China.

Over one million high energy consuming distribution transformers in China

Currently, according to statistics, there are over one million high energy consuming distribution transformers of S9 type and below still in operation nationwide.

With the increasing investment in distribution automation construction and rural power grid renovation, the market capacity of new energy-saving distribution transformers such as amorphous alloy distribution transformers, S13 three-dimensional coiled iron core distribution transformers, automatic capacity and voltage regulation distribution transformers, and high overload capacity distribution transformers will rapidly expand. ”The relevant person in charge of a certain group said in an interview with reporters that the transformer market in China is growing rapidly and has become the second largest international market, which will lead the development of global distribution network construction.

In Song Zhichen's view, there are two factors driving the strong growth of the transformer market. On the one hand, the upgrading and transformation of traditional transformers will generate a large market share, and the elimination of outdated products can promote the effective development of bidding work, resulting in significant economic benefits.

On the other hand, the research and development, manufacturing, sales, use, and maintenance of energy-saving and intelligent transformers will become mainstream, and new products will inevitably bring new development opportunities to the industry. The growth of electricity demand in China, India, and the Middle East has become the main driving force for the expected growth of the global power transformer market.

In addition, the demand for replacing and upgrading old transformers in North America and Europe has also become a major driving force in the market.

According to expert analysis, the renovation of domestic rural power grids has provided strong impetus for the increase in demand for transformers in the market.

The new round of rural power grid renovation and upgrading in China has achieved positive results. As of November 2013, the two major power grid enterprises have completed a new round of rural power grid renovation and upgrading, and invested 276.18 billion yuan in power construction in areas without electricity. The transformation of rural power grids will directly increase investment in power grid construction, expand the market share of the power equipment manufacturing industry, and usher in a new period of development opportunities for the transformer industry.

New energy-saving transformers welcome development opportunities

The continuous improvement of environmental protection requirements in the electricity market will inevitably prompt the transformer industry to make efforts in product energy conservation and emission reduction, and promote the development of energy-saving transformers. A relevant person in charge of a certain enterprise analyzed the current situation of transformers and believed that in the face of the serious overcapacity in the traditional transformer industry, the country encourages the development of energy-saving and intelligent distribution transformers, and new energy-saving transformers will usher in a new round of development opportunities.

China will further increase its efforts in energy conservation and emission reduction, promoting the development of energy-saving products for transformers. China first proposed specific greenhouse gas emission reduction targets before the Copenhagen International Climate Conference, which aims to reduce carbon dioxide emissions per unit of gross domestic product (GDP) by 40% to 45% compared to 2005 by 2020. The Ministry of Industry and Information Technology has clarified that by 2015, the energy consumption, carbon dioxide emissions, and water consumption per unit of industrial added value in China will be reduced by 18%, over 18%, and 30% respectively compared to the end of the 11th Five Year Plan period. The comprehensive utilization rate of industrial solid waste will be increased to around 72%.


Overcapacity, multiple quality hazards, and industry dispersion have become industry challenges that cannot be ignored in the entire transformer industry. How to break through these challenges has always been a common concern among industry insiders. The national energy-saving and emission reduction policies may provide an export for the transformer industry in difficult times, "Song Zhichen analyzed. As early as August 21, 2012, the State Council issued a detailed draft of the "Twelfth Five Year Plan for Energy Conservation and Emission Reduction", which clarified the specific goals and investment plans for energy conservation and emission reduction during the "Twelfth Five Year Plan" period. It required a reduction in power transformer losses during the "Twelfth Five Year Plan" period, with no-load losses reduced by 10% to 13% and load losses reduced by 17% to 19%. This undoubtedly provided policy support for the promotion of energy-saving transformers.

It is understood that distribution transformers have undergone replacement and development of S7, S9, S11 and other types since the 1980s, and the energy consumption of transformers has been continuously reduced. When transformers with better energy-saving effects are introduced, their trend of replacing existing transformers will not change. Compared with traditional silicon steel transformers, amorphous transformers have reduced no-load losses by about 80% and no-load currents by about 85%, with significant energy-saving effects. They are currently the most ideal distribution transformers for energy-saving, especially suitable for rural power grids and developing areas with low utilization rates of distribution transformers.

As a new type of energy-saving transformer, the automatic capacity and voltage regulating transformer has energy-saving effects comparable to amorphous alloy transformers, lower prices, good social benefits, and broad market prospects. The State Grid Corporation of China's Key Promotion of New Technologies Catalogue (2014 Edition) requires that from 2014 to 2016, automatic capacity and voltage regulating transformers should not be less than 15% of the newly added distribution transformers.

According to expert analysis, "phasing out high energy consuming transformers" is no longer a recommended clause that is "mediocre but useless". China's energy efficiency standards are mandatory standards, and high-energy consumption products that need to be eliminated will be listed in the "Catalogue of High Energy Consumption Product Elimination" to provide guidance and basis for the specific implementation of the terms. This provides a broad market development space for the development of new energy-saving transformers. China Electric Power
