2022-06-11206 have been browsing

Analysis of the development status of high-voltage switchgear in 2018 Production growth and market concentration gradually increased
In 2016, the country produced a total of 19205 GIS (gas-insulated metal-enclosed switchgear) with voltage levels of 126kV and above, and the compound growth rate from 2009 to 2016 was 7.03%. From the perspective of subdivided products, during the “Twelfth Five-Year Plan” period, the output of 550kV GIS increased rapidly. According to the preliminary statistics of the Prospective Industry Research Institute, the output of GIS with a voltage level of 126KV and above in 2017 exceeded the 21,000 interval mark, reaching about 21,433 intervals.

 

From the current practice, GIS has the characteristics of safety and reliability, flexible configuration, strong environmental adaptability, long maintenance period and convenient installation. At present, in the 63-500kV power system in our country, the application of GIS has been quite extensive.

 

From the perspective of the competition pattern, the number of GIS manufacturers in my country is increasing, including state-owned enterprises, joint ventures, and private enterprises. But in general, Xi’an Xikai High Voltage Electric Co., Ltd., Henan Pinggao Electric Co., Ltd., and New Northeast Electric (Shenyang) High Voltage Switchgear Co., Ltd. occupy the main market share, and these three companies have the ability to produce 1100kV voltage level Ability.

 

With the continuous construction of UHV projects during the “Twelfth Five-Year Plan” period in my country, the demand for UHV equipment will increase rapidly. my country’s UHV equipment focuses on the localization process, which will inevitably promote the research and development of UHV technology in my country. At that time, the high-end equipment market will gradually be concentrated in the hands of domestic enterprises, and domestic enterprises with high-end technology will continue to increase.

 

2. The high-end market of high-voltage AC circuit breakers is occupied by foreign brands

 

From 2010 to 2016, the output of high-voltage AC circuit breakers in my country increased year by year, reaching 9,775 units in 2016; it is predicted that the output of high-voltage AC circuit breakers with voltage levels of 126KV and above in 2017 will reach about 9,916 units.

From the perspective of the competition pattern, at present, several Sino-foreign joint ventures have obvious advantages in circuit breakers with voltage levels of 252kV and above, such as Siemens, Alstom, ABB, Areva and other enterprises; domestic manufacturers such as Pinggao Group, Xi’an West Electric Switch Electric Co., Ltd., Shandong Taikai, Shanghai Huatong, etc., compared with imported or Sino-foreign joint venture products, have certain advantages in price, and their performance can also meet the requirements. Still need to be further improved. In the market of circuit breakers with voltage levels of 110kV and below, ABB and Siemens still occupy a large market share; domestic companies such as Pinggao Electric and China Xidian can also compete with them, and their market shares are not much different. On the whole, there is still a gap between domestic brands and foreign brands in terms of quality and reliability, and foreign brands occupy the high-end market.

 

3. The market concentration of 40.5kV AC metal-enclosed switchgear is low

 

In 2016, the output of metal-enclosed switches in my country was 510,400 pieces, of which the output of 40.5KV was 78,124 pieces, the output of 24KV was 9,602 pieces, the output of 12KV voltage products was 418,466 pieces, and the output of 27.5/55KV voltage products was 3,247 pieces. It is estimated that the output of 40.5KV in 2017 will exceed 80,000, reaching 81,130.

In my country’s AC metal-enclosed switchgear market, the main manufacturers of 40.5kV high-voltage AC metal-enclosed switchgear are Henan Senyuan Electric Co., Ltd., Jiangsu Dongyuan Electric Group Co., Ltd., Huapeng Group Corporation, and Taikai Electric Group Co., Ltd. The company and Huayi Electric Group Co., Ltd., etc., five companies occupy about 30% of the market share.

 

There are many manufacturers of AC metal-enclosed switchgear, the market concentration is relatively low, the technical threshold of equipment is not high, and the market competition in this equipment field is fierce. With the continuous development of the high-voltage switch manufacturing industry, the number of manufacturers of AC metal-enclosed switchgear will gradually increase, and the market capacity will expand while the competition of enterprises will continue to intensify.

 

Fourth, the high-voltage AC switch market is dominated by domestic enterprises

 

From 2009 to 2016, the output of high-voltage AC disconnectors in my country showed an upward trend year by year. In 2009, the output of high-voltage AC isolation switches in my country was 290,000 sets, and by 2016, the output reached 870,000 sets, with an average annual growth rate of 12%. According to forward estimates, the annual output in 2017 will reach about 980,000 sets.

 

From 2009 to 2016, the output of high-voltage AC grounding switches in my country showed an upward trend year by year. In 2009, the output of high-voltage AC grounding switches in my country was 220,000 sets, and it reached 540,000 sets in 2016, with a relatively fast growth rate. According to forward estimates, the output in 2017 will be around 610,000 units.

Because the higher the voltage level of the AC switch, the higher the technical requirements for it, forming a higher industry entry barrier. Therefore, the market concentration of the high-voltage level AC switch is high, and the industry competition pattern is relatively stable. At present, the production of high-voltage grade AC switches is mainly concentrated in the following companies: Hunan Changgao High-voltage Switch Group Co., Ltd., Henan Pinggao Electric Co., Ltd., Xi’an Xidian High-voltage Switch Co., Ltd., New Northeast Electric (Shenyang) High-voltage Switch Co., Ltd. , Jiangsu Province, such as high-voltage electrical appliances Co., Ltd., Shandong Taikai isolation switch Co., Ltd., Siemens (Hangzhou) high-voltage switch Co., Ltd., Suzhou Areva high-voltage electrical switch Co., Ltd., and so on.

 

In general, in the high-voltage AC isolation switch and grounding switch market, domestic enterprises dominate the market, and foreign-funded enterprises have taken a certain market share in voltage levels of 550kV and above by virtue of their technical advantages in recent years.
