China's Transformer Industry Policy Summary and Interpretation 2023

Since the founding of the People's Republic of China, the policy on Power Transformers has primarily focused on fostering technological advancement and industrial growth. By 2016, China's power transformers had achieved an internationally leading technical level. In response to the growing challenges of resource scarcity and environmental degradation, national policies have shifted towards promoting the development of high-efficiency and energy-saving transformers. Additionally, there is a strong emphasis on the digitalization, greening, and intelligent development of the industry.

To enrich the content and include the terms "Oil-Filled Transformer," "Oil-immersed Transformer," and "electrical transformers," let's delve deeper:

1. Oil-Filled Transformers (Oil-Immersed Transformers): These are electrical transformers where the core and the winding assembly are submerged in a dielectric oil, which serves as both an insulator and a coolant. The oil-filled transformer is housed in a steel tank filled with transformer oil that encloses the internal components. This design is effective in dissipating heat generated during operation, as the oil absorbs the heat and transfers it to the external environment. They are commonly utilized in generating stations, distribution systems, transmission systems, and outdoor substations.

2. Electrical Transformers: Transformers are electrical devices that transfer electrical power between circuits through electromagnetic induction. They play a crucial role in increasing voltage for transmission and decreasing it for distribution to end-users. Electrical transformers can be categorized into different types based on their application, such as large power transformers, medium power transformers, and distribution transformers. They can be liquid-filled, cooled with mineral oil or other insulating liquids, or dry-type, cooled with air.

3. High-Efficiency and Energy-Saving Transformers: With the push towards sustainability, there is a focus on developing transformers that offer greater efficiency and energy savings. These transformers are designed to minimize energy loss during the transformation process, thereby reducing environmental impact and operational costs.

4. Digitalization of Transformers: The integration of digital technologies, such as sensors and data analytics, allows for real-time monitoring and predictive maintenance of transformers. This enhances their reliability and efficiency.

5. Greening of Transformers: This involves the use of environmentally friendly materials and processes to reduce the carbon footprint and environmental impact of transformer manufacturing and operation.

6. Intelligent Development of Transformers: The industry is moving towards the development of smart transformers that can self-monitor, self-diagnose, and optimize performance, contributing to a more resilient and efficient energy grid.

By incorporating these elements, the policy on power transformers in China not only addresses the immediate needs of the industry but also aligns with global trends towards sustainability and technological advancement.
