The EU-China Energy Saving Transformer Promotion Project was launched in Beijing.

The project was jointly initiated by the International Copper Association (China) and the China National Institute of Standardization, the China Electrical Appliance Industry Association, the China Electricity Council, and the French Sustainable Development Association. In the next three years, we will further promote the revision and implementation of China's distribution transformer energy efficiency standards and life cycle assessment methods.

It is understood that the power transformer is the key electrical equipment for power transmission, and its loss accounts for 30% to 40% of the loss in the power grid. However, the loss of all transformers in China accounts for more than 3% of the national power generation.

The project aims to increase the energy and resource use efficiency of transformers in production and use, and promote the contribution of transformers in energy conservation and emission reduction. If the energy saving of the transformer in the project is achieved, 88.70 million kWh of electricity will be saved per year and the target of reducing emissions by 840,000 tons of carbon dioxide will be achieved.

In the same period, the Institute of Standardization and the Copper Industry Association also held the National Compulsory Standard GB24790-2009 “Energy Efficiency Limits and Energy Efficiency Ratings of Power Transformers”, and the five companies including TBEA became the first batch of certified energy transformer manufacturers. .

The standard was formally released on December 15 last year and was implemented on July 1 this year. Its purpose is to improve and promote the use of energy-saving transformers in the power system. Zhao Yuejin, a senior engineer at the China National Institute of Standardization, stated: "After completing the replacement of transformers, it is expected to save an average of 3.86 billion kilowatt-hours of electricity annually. Based on the economic operation period of transformers (20 years), a total of 70 billion kwh can be saved. The amount of electricity used, equivalent to 32 million tons of standard coal, can reduce carbon dioxide emissions by 69 million tons and reduce sulfur dioxide emissions by 3.9 million tons.This will not only save energy, but also guide the company’s energy-saving technological progress and increase the power transformers. Products are competitive in the international market."

The energy-saving and miniaturization of transformers will become the mainstream of the electric energy industry. Mr. Zhou Sheng, President of China Copper & Copper Industry Association, said: “The International Copper Industry Association’s energy and power projects have long been dedicated to promoting the optimal use of copper in the electric energy field and will continue to encourage the use of energy-saving transformers in the electric energy industry in China. Promote industrial energy conservation, emission reduction and environmental upgrades."
