In December 2016, the National Development and Reform Commission and the National Energy Administration officially issued the "Thirteenth Five Year Plan for Electric Power Development", setting green and efficient as the main tone of electric power development in the "Thirteenth Five Year Plan". They proposed to focus on improving the efficiency of the electric power system, adhere to ecological priority, energy conservation and emission reduction, green development, and build a clean, low-carbon, safe and efficient modern electric power industry system.

To achieve green and efficient development of the power industry, it is necessary to start from various aspects such as power generation, transportation, and distribution, strengthen overall coordination, optimize the allocation of power resources, and promote the construction of a safe, reliable, economically efficient, and environmentally friendly power grid. As an important part of the power supporting industry, wires and cables are no exception. Wires and cables that conform to the future direction of power development should not only improve power transmission efficiency, but also meet energy-saving and environmental protection requirements to support the sustainable development of the power industry.

Among various cable types, copper cable is the most suitable cable material for China's power development direction. Copper cables have good technical advantages in terms of transmission efficiency and power supply reliability. Copper cables have high conductivity and large current carrying capacity, enabling efficient transmission of higher power currents. At the same time, copper cables have excellent mechanical properties and are widely recognized as the best performing electrical conductor material in the industry. They can effectively alleviate voltage drops, reduce line losses, improve the reliability of power supply systems, and provide strong guarantees for efficient power transmission.

In addition, copper itself has excellent energy-saving and environmental protection properties. According to the "Environmental Assessment Report on the Whole Life Cycle of Copper Aluminum Cables" released by the China Institute of Standardization, the impact of copper cables on the environment during use is much smaller than that of other cables. From the perspective of sustainable development, copper can be 100% recycled and reused. Copper cables are both products and resources. In the power cable industry, the proportion of recycled copper usage is about 50%. It is worth mentioning that compared to native copper, recycled copper has a relatively reduced impact on the environment. With the increasing importance of ecological environment, copper cables are undoubtedly the main force of green and environmentally friendly cables.

With the rapid development of the power industry and the adjustment of the national energy strategy, green and efficient as the main tone of power development are increasingly deeply rooted in people's hearts, and the series of changes brought about by this also pose significant challenges to the power industry. With unparalleled technological advantages and environmental performance, copper cables will undoubtedly play an important role in the sustainable development of the power industry in the future.
