The 20th China Manufacturing Expo released a number of domestic high-quality goods

The 20th China International Equipment Manufacturing Expo (hereinafter referred to as China Manufacturing Expo) was held in Shenyang International Exhibition Center on October 24 (Li Xian). During the period, new products, new technology conference became a highlight of the current China Manufacturing Expo. A number of enterprises showed their expertise in the industrial field through the window of the expo.

Staff from Shenyang Huavi Laser Equipment Manufacturing Co., Ltd. unveiled the company’s newly developed high-power continuous fiber laser cleaning machine. According to introducing, laser clean has the characteristic that does not grind, be not contacted, do not have heat effect and apply to all sorts of material to pledge, be considered to be the most reliable, the most effective solution.

The introduction of this as a new product, mainly because the original laser cleaning machine has been using a semiconductor laser, low power, equipment procurement costs are high, so for a long time can not really enter the ordinary factory for application. And huavi Laser is now launched on the basis of high power continuous fiber laser laser cleaning equipment, with high energy density, large power, stable operation, faster cleaning, higher efficiency. The greater advantage lies in greatly reducing the cost of equipment procurement, so that customers can use the most advanced equipment at a more favorable price.

Connecting transformers for flexible DIRECT current transmission from offshore wind power may sound like a long way off, but the numbers are proof of its importance in the real world: 2.4 billion kilowatt-hours of electricity a year, enough to power a million homes. The coupling transformer for the three Gorges such as The East China Sea wind flexible HVDC transmission released by TBEA Shenyang Transformer Group Co., Ltd. will effectively help achieve the goal of “carbon peak and carbon neutralization”.

The Three Gorges Rudong Offshore Wind Flexible DIRECT current transmission Project is the first offshore wind farm project in China to adopt flexible DIRECT current transmission. When put into operation, it will gather 1,100 MEGAwatts of electricity from the Wind farm in the East China Sea, and generate 2.4 billion kilowatt hours of online electricity annually, which can meet the annual electricity consumption of 1 million households. Compared with coal-fired power plants of the same size, it can save about 740,000 tons of standard coal and reduce carbon dioxide by about 1.83 million tons per year.

As the “heart” of power transmission in the offshore converter station of the project, the connecting transformer is the world’s first ±400kV three-phase integrated flexible DC connecting transformer for offshore wind power with the largest capacity. It is independently developed by TBEA Shenyang Transformer Group Co., LTD. This product has the characteristics of special structure and complex technology. As the core equipment of the project, the successful development of the offshore wind power flexible DC coupling transformer has achieved a leading position in the offshore wind power flexible DC transmission technology of high voltage level, and realized the localization of electrical equipment.

In addition, with fully independent intellectual property rights and ultra-low carbon emissions, such domestic high-quality products make Chinese intelligent manufacturing have more say in the world. The self-developed AGT-110 low-emission gas turbine, released by AvIC Gas Turbine Co., LTD., catches the eye. This low-emission gas turbine is a 100 MW class gas turbine with complete intellectual property rights. It can use natural gas, medium-low calorific value syngas and industrial exhaust as the main fuel for base load and peak load power generation. After the combined cycle is configured, its power generation efficiency exceeds 50%, and the annual power generation can reach 1.3 billion KWH (calculated at 8,000 h), which is equivalent to one-thirtieth of shenyang’s annual electricity consumption.
