Analysis of the development direction of the power transformer industry this year

Power transformer is the key electrical equipment for power transmission, transformer loss accounts for 30% ~ 40% of the power grid loss, and China's transformer itself loss accounts for more than 3% of the national power generation. China's "Twelfth Five-Year Plan for Energy Conservation and Emission Reduction" requires the "Twelfth Five-Year Plan" period to reduce the loss of power transformers, including no-load losses reduced by 10% ~ 13%, load losses reduced by 17% ~ 19%, and some high-energy consumption distribution transformers currently operating on the network have not met the development trend of the industry. The state has been promoting the energy saving and consumption reduction of transformers. At the beginning of the new year, Tian Wei of the National Power Transmission and Distribution Technology Cooperation Network Substation Branch expressed his views.

At present, China's energy-saving distribution transformer market is scattered, coupled with the low entry threshold, uneven enterprises, lack of identification and standards, poor technological innovation, high prices, insufficient subsidies and other factors, resulting in the slow promotion of energy-saving transformers in China. The National Transmission and Distribution Technology Cooperation Network Substation Branch will take a wait-and-see attitude towards the overall development trend of energy-saving transformers in 2014.

On the one hand, in the process of promoting energy-saving transformer products, because the sales price of energy-saving transformers is higher than the price of traditional transformers, the price is still the main factor affecting the popularization and promotion of energy-saving transformers. At present, the energy-saving subsidy project is still in its infancy, and the state has not yet formulated a clear policy on the energy-saving subsidy policy. State Grid Corporation of China on 2013 the fourth batch of bidding work has no implementation rules and documents, energy-saving transformer-related topics to promote progress is slow, China Southern Power Grid Corporation does not have any corresponding measures, in 2014 the promotion of energy-saving transformers in the policy environment is still unclear under the premise, the development will be difficult.

On the other hand, in 2013, the Standardization Administration of the People's Republic of China issued the GB20052-2013 "Energy Efficiency Limits and Energy Efficiency Grades of Three-phase Distribution Transformers", which was implemented on October 1, 2013, and the application for energy-saving certification certificate was also closed on December 31, 2013. In the past, the era of distribution transformers divided by S7, S9, S11, etc. has ended, and the future measurement of whether the transformer is energy-saving will be divided into energy efficiency first, second, and third, and the energy efficiency standard has opened a new era of energy-saving transformers. The new energy efficiency standard puts forward higher energy efficiency requirements for products, and some high-energy consumption products will be withdrawn from the market, but some companies have not yet implemented this standard, so some companies will phase out some high-energy consumption products in 2014.

It is expected that in 2014, the energy-saving transformer industry will still face a more complex development situation. Affected by factors such as the decline in the growth rate of fixed investment of large power users and the continued rise in operating costs, the energy-saving transformer industry will maintain a "stable" trend in 2014, and the probability of strong recovery is not large. In terms of exports, it will continue to be mainly exported to Southeast Asia and other regions.

In 2014, under the background of the in-depth implementation of the "Industrial Transformation and Upgrading Plan" and the "Strategic Emerging Industry Development Plan", under the forced mechanism of domestic and foreign demand upgrading, it will still take some time to complete the task of "de-capacity and de-bubble", and the domestic demand for products will not increase significantly. However, with the introduction of a new round of reform policies and measures to release the impact of development dividends, the energy-saving transformer industry will burst out with new impetus and growth points. It should be said that energy-saving transformers have been the trend of the times, and China is also improving the relevant standards for energy-saving transformers, and at the same time, it is recommended to introduce the "Guidelines for Transformer Selection" to further standardize the industry market. Looking forward to 2014, the energy-saving transformer industry should not only promote the reform of energy efficiency standards and subsidy mechanisms, but also further promote the large-scale application of energy-saving transformers in terms of business models, technological breakthroughs, and the application of new materials.
