In December 2016, the National Development and Reform Commission and the National Energy Administration formally issued the "Thirteenth Five-Year Plan" for power development, and set green and high-efficiency as the main keynote of the "13th Five-Year Plan" for power development. Power system efficiency, adhere to ecological priority, energy conservation and emission reduction, green development, and build a clean, low-carbon, safe and efficient modern power industry system.

To achieve the green and efficient development of the power industry, we need to start from all aspects of power generation, transportation, and power distribution, strengthen overall coordination, optimize power resource allocation, and promote the construction of a safe, reliable, cost-effective, 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 direction of future power development should not only improve power transmission efficiency, but also meet energy conservation and environmental protection requirements to help the sustainable development of the power industry.

Among the many cable types, copper cable is the cable material that best meets the direction of China's power development. Copper cables have good technical advantages in terms of transmission efficiency and power supply reliability. Copper cable has high conductivity and high current carrying capacity, which can efficiently realize the transmission of larger power current. At the same time, copper cables have good mechanical properties and are recognized by the industry as the best-performing electrical conductor materials. They can effectively alleviate voltage drops, reduce line losses, improve the reliability of power supply systems, and provide a strong guarantee for the efficient transmission of electricity.

In addition, copper itself has excellent energy saving and environmental protection performance. According to the "National Copper Research Institute's Life Cycle Environmental Assessment Report" issued by the China National Institute of Standardization, the impact of copper cables on the environment is much less than the impact of other cables on the environment. From the perspective of sustainable development, copper can be recycled and reused 100%. Copper cables are both products and resources. In the power cable industry, the proportion of recycled copper is about 50%. It is worth mentioning that compared to native copper, the impact of recycled copper on the environment is relatively reduced. With the increasing importance of the ecological environment, copper cables are the main force of green environmental protection cables.

With the rapid development of the power industry and the adjustment of the national energy strategy, green and high-efficiency as the main tone of power development are becoming more and more popular, and the series of changes brought about by this have also brought great challenges to the power industry. With unparalleled technical advantages and environmental performance, copper cables will definitely play an important role in the sustainable development of the power industry in the future.
