Product explan

Power transformers are key electrical equipment for power transmission. Transformer losses account for 30% to 40% of power grid losses, and transformer losses in my country account for more than 3% of the country’s power generation. The detailed draft of my country’s "Twelfth Five-Year Plan for Energy Conservation and Emission Reduction" requires the reduction of power transformer losses during the “Twelfth Five-Year Plan” period. The no-load loss is reduced by 10% to 13%, and the load loss is reduced by 17% to 19%. Some high-energy-consumption distribution transformers operated by the power grid are no longer in line with the industry development trend. The country has been promoting the energy saving and consumption reduction of transformers. At the beginning of the new year, Tian Wei, Subcommittee of the National Power Transmission and Distribution Technology Collaboration Network, expressed his views.

At present, my country's energy-saving distribution transformer market is scattered, coupled with the constraints of low entry barriers, uneven quality of enterprises, lack of identification and standards, inadequate technological innovation, high prices, insufficient subsidies and other factors, leading to the slow promotion of energy-saving transformers in my country. The National Power Transmission and Distribution Technology Collaboration Network Substation 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 that of traditional transformers, price is still the main factor affecting the popularization and promotion of energy-saving transformers. At present, the energy saving and benefiting people subsidy project is still in its infancy, and the state has not yet formulated a clear policy on energy saving and benefiting people subsidy policies. The State Grid Corporation of China has no implementation rules and documents for the fourth batch of tenders in 2013, and the promotion of energy-saving transformer-related topics is slow. China Southern Power Grid has no corresponding measures. The promotion of energy-saving transformers in 2014 is still unclear in the policy environment. Under the premise, development will be difficult.

On the other hand, in 2013, the National Standardization Management Committee issued the GB20052-2013 "Three-phase distribution transformer energy efficiency limit value and energy efficiency rating" announcement, which will be implemented on October 1, 2013. At the same time, the work of applying for energy conservation certification It also ends on December 31, 2013. In the past, the era when distribution transformers were divided into S7, S9, S11, etc. has ended. In the future, the energy-saving measures of transformers will be divided into the first, second and third levels of energy efficiency. Energy efficiency standards have opened a new era of energy-saving transformers. The new energy efficiency standards put forward higher energy efficiency requirements for products. Some high energy consumption products will be withdrawn from the market, but some companies have not yet implemented this standard, so some companies will gradually phase out some high energy consumption products in 2014. It is estimated that in 2014, the energy-saving transformer industry will still face a more complicated development situation. Affected by factors such as the decline in fixed investment growth 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 chance of a strong recovery is unlikely. In terms of exports, exports 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 upgrades, the task of "de-capacity and de-bubble" still needs some time to complete. Over time, 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 new impetus and growth points. It should be said that energy-saving transformers are the general trend, and our country is also improving the relevant standards for energy-saving transformers. At the same time, it is recommended to issue "Guidelines for Transformer Selection" to further standardize the industry market. Looking forward to 2014, the energy-saving transformer industry will not only promote the reform of energy efficiency standards and subsidy mechanisms, but also need to further promote the large-scale application of energy-saving transformers in terms of business models, technological breakthroughs, and the use of new materials.
