Distribution transformers are the core equipment of power transmission. About 600,000 new units are added to the grid in China every year, and the total amount in operation reaches 17 million units. At present, the national power transmission and distribution loss accounts for 6.6% of power generation, of which the loss of distribution transformers accounts for 40%-50%. The annual power loss is about 230 billion kilowatt-hours, which is equivalent to the annual power generation of 2.3 Three Gorges Power stations, and the energy-saving space is very considerable.
From a global perspective, high efficiency and environmental protection are already a major trend in the transformer industry. There are unified international energy efficiency standards for distribution transformers, and the first-level energy efficiency is the highest level. The European Union, Japan, India, etc. are all promoting stricter energy efficiency policies: the European Union launched the "Distribution Transformer Promotion Partner Program" as early as 2005, Japan implemented the "Transformer Energy Efficiency Leader Program" in 2006, and India is also preparing for mandatory first-level energy efficiency standards. My country also released a new version of the transformer energy efficiency standard in 2021, officially transitioning to high-efficiency and energy-saving.
To make high-efficiency and energy-saving transformers, core materials are the key. Baowu Group and Shougang Group jointly researched and successfully developed high-end oriented silicon steel. The technical level basically caught up with Nippon Steel of Japan. Now it has the ability to supply in bulk and can be used to produce energy-saving transformers that meet new energy efficiency standards.Ansteel and TISCO are also simultaneously promoting research and development, laying a material foundation for the large-scale production of high-efficiency and energy-saving transformers in China.
Advantages for Distribution Transformers
If we upgrade and replace the transformers with three-stage energy efficiency and below in operation in batches, it will bring real benefits:
Strengthen the silicon steel industry: promote the formation of an annual production capacity of 600,000 tons of silicon steel dominated by the 080 level and supplemented by the 085 and 075 levels in China, and the technical level is at the forefront of the world.
Energy saving and carbon reduction: strictly implement the new energy efficiency standards, significantly reduce the iron loss of transformers, save energy and reduce pollution, and help the national "double carbon" goal.
Improve the level of manufacturing: Force transformer companies to accelerate product upgrading, transform into high-efficiency and energy-saving products, and solve the industry problem of inferior transformers made of waste silicon steel from the root cause.
Driving economic growth: It is expected that nearly 2 million energy-saving transformers will be updated and nearly one million new energy-saving transformers will be added every year, with an annual production capacity demand of 3 million units, which can form a considerable output value and drive the development of upstream and downstream industries.
Expand overseas markets: Taking advantage of the opportunities of the "Belt and Road", we will bring our high-efficiency and energy-saving transformers and technologies to the international market and expand export trade.
Relying on the technological breakthroughs of domestic high-end oriented silicon steel, we focus on the research and development and production of high-efficiency and energy-saving transformers that meet national first-class energy efficiency standards.
The product has lower loss and higher reliability, and is suitable for various scenarios such as power grids, industry, construction, and new energy. It can help customers recover their investment through electricity bill savings within 3-5 years. At the same time, our products also meet international energy efficiency requirements, can undertake export orders and "Belt and Road" projects, and provide customers with full-cycle services from product to operation and maintenance.
