UHV construction promotes the need for electrical testing equipment

China's investment in UHV smart grid construction is huge and it will invest over 600 billion yuan in the next five years. According to Zhang Zhengling, director of the State Grid Development and Planning Department, “The UHV smart grid is necessary for the development of the power in the Mainland. In the next five years, the State Grid will invest 620 billion yuan to build 20 UHV lines to connect southwest hydropower and northwest wind power. Transmission to Eastern China At present, China’s UHV power grid has completed one UHV AC line and two UHV DC lines, totaling 4,633 kilometers; there are two AC and two DC lines under construction, reaching 6412 kilometers; It is a golden period for UHV construction in China, and the large-scale construction of UHV will surely drive the demand for product research and development and bidding, which is expected to promote the development of high-voltage electrical testing.

The company ranks among the top four high-voltage electrical testing institutions in the country, and UHV testing is expected to reach the world-class level. The company began to build high-voltage electrical test and test systems in 2007. At present, the company has already put into operation the 35kv, 220kv, and 550kv high-voltage electrical test systems, and it has developed rapidly, ranking among the top four high-voltage electrical testing institutions in the country. The company's high-voltage and nuclear power equipment seismic performance test system put into operation this year has expanded the company's test capability to 1100kv voltage level. The company's 1100kv 100ka test power system is being built to further strengthen the company's UHV electrical testing capabilities. After the completion of construction, the company's 1100kv grade high-voltage electrical appliances The test system is expected to reach world-class standards.

The large-scale construction of UHV smart grids has led to the rapid development of the company's high-voltage electrical testing. According to the requirements of the State Grid, bidders of the State Grid must obtain a type test report issued by a state-level authoritative inspection and testing agency. The company has been listed by the State Grid Corporation of Materials for the first time on the list of eight types of primary equipment type test reports, and is also authorized to National Smart Grid High Voltage Complete Equipment Quality Supervision and Inspection Center. At the same time, the company also signed a technology exchange cooperation agreement with the State Grid Electric Power Research Institute Wuhan Nanrui Company, focusing on improving the company's ability to test and test primary and secondary equipment of 1000kv and below.
