The core data of this paper: China power transmission and transformation equipment industry chain, China power transmission and transformation equipment demand, etc.

General situation of industry

Definition: Power transmission and distribution equipment covers a wide range.

Power transmission and distribution equipment can be divided into primary equipment and secondary equipment according to their functions. The primary equipment is mainly used for power transmission, including transformers, switches, transformers, insulators and lightning arresters. Secondary equipment is mainly used to protect, measure and control power equipment, including relays, measuring instruments and signal equipment.

Industrial chain analysis: the downstream is mainly in the field of electricity consumption.

The upstream of transmission and distribution equipment industry chain mainly includes steel, copper, components and other raw materials needed to produce transmission and distribution equipment; Power transmission and distribution equipment manufacturers can be divided into primary equipment manufacturers and secondary equipment manufacturers; The downstream of transmission and distribution equipment is mainly in the field of electricity consumption, including power production, power supply and rail transit.

The upstream raw material manufacturers of transmission and distribution equipment mainly include Sheng Hui Science and Technology, Baiyin Nonferrous Metals, Northern Copper, Baosteel Group, Baotou Steel Group and other raw material manufacturers. Buyers of transmission and distribution equipment are mainly State Grid and China Southern Power Grid.

Industrial development process: the industry is developing continuously and is in a golden period of development.

With the development of China's electric power industry, China's power transmission and distribution and control equipment manufacturing industry began in the 1950s. It has experienced germination, precipitation, industrial formation and blond hair extension. Since the 20th century, with the development of urbanization and the acceleration of construction in China, the production of transmission, distribution and control equipment has also ushered in a golden period of development, and the technical level and ability of transmission, distribution and control equipment manufacturing in China are within the Ministry.

The field has reached the international leading level, and the capacity, output, voltage grade and capacity of transmission and distribution and control equipment such as transformers and complete sets of electrical switchgear have been greatly improved.

Upstream supply: there are many kinds of raw materials.

The main raw material of power transmission and distribution equipment is silicon steel, which is called "handicraft" in steel products because of its complicated production technology and strict production technology. Due to the continuous progress of steelmaking technology in China and the increasing number of silicon steel production lines, the supply of silicon steel in China can basically meet the domestic demand. 20 13-202 1 the overall output of silicon steel in China fluctuated and rose. In 2002 1 year, the national silicon steel output was about13.28 million tons, up by 17.9% year-on-year, of which oriented electrical steel was about1800,000 tons, up by1year-on-year. Non-oriented electrical steel is about11380,000 tons, with a year-on-year increase of 18.5%.

Copper is widely used in electrical and electronic industries, accounting for more than half of the total consumption. Used for winding all kinds of cables and wires, capacitors and transformers, switches and printed circuit boards. As one of the important raw materials of power transmission and distribution equipment, the supply and price trend of electrolytic copper directly affect the manufacturing cost of power transmission and distribution equipment.

From the domestic electrolytic copper output, from 20 12 to 202 1 year, China's electrolytic copper output maintained a relatively stable growth, and the growth rate slowed down. In 202 1 year, the output of electrolytic copper in China was104.87 million tons, up by 7.4% year-on-year. Overall, the output of electrolytic copper in China has maintained a relatively stable growth trend, and the growth rate has slowed down in recent years.

Aluminum and its alloys are one of the most widely used and economical materials at present. The conductivity of aluminum is second only to that of silver, copper and gold. Although its conductivity is only 2/3 of that of copper, its density is only13 of that of copper, so the quality of aluminum wire is only half that of copper wire when transmitting the same amount of electricity. The oxide film on aluminum surface not only has corrosion resistance, but also has certain insulation, so aluminum is widely used in electrical appliance manufacturing, wire and cable industry and radio industry. From the domestic aluminum output, the aluminum output in China fluctuates greatly from 20 15 to 202 1. In 202 1 year, China's aluminum output was 610.52 million tons, up 5.6% year-on-year.

Downstream application: Power system construction is the main application field.

Power transmission and distribution and control equipment are mainly used in State Grid, provincial and municipal power grid companies, power generation enterprises, automobile manufacturing, metallurgy and chemical industry, rail transit and other fields. The development of downstream industries directly determines the development of power transmission and distribution and control equipment manufacturing industry. Downstream customers generally make investment plans of the year in the first quarter of each year, and then organize their implementation one after another. The operation of industrial enterprises has seasonal characteristics.

From 20 14 to 20021year, China's investment in power engineering construction showed a fluctuating growth trend, which showed that the investment in power engineering construction was relatively high in the first two years of the five-year plan, and relatively low in the following years, reflecting certain cyclical characteristics. In 20021year, China's investment in power engineering construction was 1048 1 billion yuan, up by 2.9% year-on-year.

During the period of 20 17-202 1, the total investment in power supply infrastructure in China increased year by year. In 2020, China's power infrastructure investment was 524.4 billion yuan, a year-on-year increase of 67%; In 20021year, China's power supply capital construction investment further increased, reaching 553 billion yuan, a year-on-year increase of 5%.

During the period of 20 17-202 1, the total investment in power grid construction in China decreased first and then increased. In 2020, the investment in power grid construction in China was 489.6 billion yuan, up by1%year-on-year; In 20021year, the investment in power grid construction in China was 495 1 billion yuan, up 1% year-on-year. Generally speaking, the investment in power grid construction projects in China has grown slowly in the past three years.

According to the "14th Five-Year Plan" of China Southern Power Grid, China Southern Power Grid will plan to invest about 670 billion yuan to accelerate the construction of digital power grid and modern power grid and promote the construction of a new power system with new energy as the main body. At the same time, the State Grid announced that it will invest about 350 billion US dollars (about 2.23 trillion RMB) in the construction of modern power grid during the Tenth Five-Year Plan period.

From 20 17 to 202 1 year, the installed capacity of solar generators in China increased rapidly year by year. In 20021year, the installed capacity of solar generators nationwide was 306.56 million kilowatts, up 20.96% year-on-year.

Present situation of industrial development

Supply: There are a large number of exhibitors and a variety of products.

After years of development, in most areas of power transmission and distribution, China's power transmission and distribution equipment manufacturing enterprises have already had sufficient production capacity. At present, the main producers of transmission and distribution equipment in China are china xd, TBEA, Baobian Electric, Gao Ping Electric, Zhengtai, State Grid Ying Da, Radio and Television Electric, Xuji Electric, Guo Nan Electric, Sifang Co., Ltd., and Guodian Nanzi. At present, the main products produced by China power transmission and distribution manufacturers include transformers, distribution switchgear, reactors, transformers, insulators, lightning arresters, distribution protection monitoring and intelligent substations.

Demand: there are many types of demand and a large amount of bidding.

In 20021year, the State Grid conducted a unified tender for 2798 packages of 20 kinds of materials, with a tender amount of 44.5 billion yuan. Among them, 273 enterprises won the bid. Of the 273 enterprises that won the bid, 146 exceeded 50 million yuan, 97 exceeded 1 100 million yuan, 46 exceeded 300 million yuan, 29 exceeded 500 million yuan, 6 exceeded 1 100 million yuan, and the highest one exceeded1500 million yuan. Among the top 100 companies, 38610.82 million yuan was packaged in 2007, accounting for 86.8% of the total, with a high concentration.

Note: The bidding data only includes the unified bidding of state grid substation equipment, excluding the bidding volume of single products and the bidding volume of local companies.

Price: The price performance of different categories of products is quite different.

There are many kinds of transmission and distribution equipment, and the characteristics, functions and specifications of products are very different, so the prices of different products of different transmission and distribution equipment enterprises are very different. Because China's power transmission and distribution equipment mainly obtains orders through the bidding of State Grid and China Southern Power Grid, and the degree of marketization is high, the product prices of China's power transmission and distribution equipment head enterprises are highly representative.

2020-202 1 The trend of transmission and distribution equipment products of representative enterprises in China shows that the prices of distribution transformers and electrical appliances will increase in 2020-202 1 China; At the same time, the price of switching equipment in distribution network, whether it is high-voltage switch or medium-low voltage switch, has declined to varying degrees.

Industrial competition pattern

Regional competition: East China is dominant, and Jiangsu and Zhejiang are the most concentrated.

At present, there are a large number of enterprises producing or selling transmission and distribution equipment in China. According to enterprise survey statistics, by the end of 2022 10, there were more than 30,000 enterprises producing transmission and distribution equipment in China. From the perspective of enterprise distribution, domestic power transmission and distribution equipment enterprises are mainly concentrated in East China, with Jiangsu, Zhejiang and other provinces and cities being the most concentrated.

Enterprise competition: market segmentation concentration.

Because there are many categories of transmission and distribution equipment industry, the market concentration of different categories of products is quite different. According to the data released by the e-commerce platform of State Grid Corporation of China, the data of two purchases of substation equipment for power transmission and transformation projects in 2022 show that the market concentration of distribution transformers, switchgear, transformers and other products is low; The market concentration of circuit breakers, reactors, insulators, relay protection and other products is relatively high.

Note: The statistical data are the procurement results of the State Grid e-commerce platform in the first half of 2022.
