Cable Industry Output Continues to Rise

Aug 25, 2023 | China News | 0 comments

Power cables are composed of four parts: core (conductor), insulating layer, shielding layer and protective layer. They are cables used to transmit and distribute electric energy. They are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and crossing rivers and seawater. Down the power line. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables.

Industry Development Status

Power cable is one of the five major subdivisions of wire and cable, which belongs to the wire and cable industry. The wire and cable industry is the second largest supporting industry in my country’s economy, second only to the automobile industry, with an annual market size exceeding one trillion yuan. In recent years, with the rapid development of my country’s urban infrastructure construction and national economy, my country’s wire and cable industry has also developed rapidly. In particular, the transformation of the power grid has been accelerated, UHV projects have been put into construction one after another, and the market of my country’s wire and cable industry has continued to develop. In 2011, the scale of China’s wire and cable industry surpassed that of the United States for the first time, becoming the largest market in the global wire and cable industry. The industry has entered a mature stage. According to sales revenue statistics, the market size of the wire and cable industry in 2021 will reach 1.12 trillion yuan, a year-on-year increase of 3.57%; the output is about 54.8 million kilometers, a year-on-year increase of 4.5%.

Industry demand market

Power cables are cable products used to transmit and distribute high-power electric energy in the backbone lines of power systems, so they are greatly affected by the power system market. During the “13th Five-Year Plan” period, my country continued to promote the construction of a strong smart grid with UHV as the backbone grid and coordinated development of power grids at all levels. A series of supporting policies have been introduced in the field of power industry development to comprehensively accelerate investment in power supporting infrastructure. . According to the 2021 National Power Industry Statistical Bulletin issued by the National Energy Administration, the investment in my country’s electric power engineering construction in 2021 will be 1,048.1 billion yuan, and the investment in power supply engineering and power grid engineering will be 553 billion yuan and 495.1 billion yuan, respectively.

According to the 14th five-year plan for national economic and social development and the 2035 long-term goal outline, it is proposed to accelerate the intelligent transformation of power grid infrastructure and the construction of smart micro-grids, improve the complementary mutual aid and intelligent adjustment capabilities of the power system, and strengthen the source, network, load and storage. Convergence, improve clean energy consumption and storage capacity, improve power transmission and distribution capacity to remote areas, promote the flexibility of coal power transformation, accelerate the construction of pumped storage power stations and the large-scale application of new energy storage technologies.

Affected by changes in the total scale of domestic grid investment and the proportion of smart grid investment, my country’s smart grid investment scale is highly variable. In 2019, my country’s smart grid investment scale was 58.85 billion yuan, and in 2020, my country’s smart grid investment scale was 587.4. billion.
