Xigaosuo Company is the base of high voltage, high current, large capacity, AC and DC technology research and development and testing of high voltage electrical products in China, and has established the National High Voltage Electrical Equipment Quality Supervision and Inspection Center, the High Voltage Electrical Equipment Accreditation Laboratory of the National Entry-Exit Inspection and Quarantine Bureau and the Fifth (Xi 'an) Metrology and Testing Center Station of the mechanical industry. Have large, complete sets, large capacity, high voltage, AC and DC test and detection equipment. At present, the synthetic test of 550kv 1/2-pole 50kA circuit breaker and the insulation test of 800kV electrical equipment can be carried out. Since its establishment, it has tested nearly 10,000 sets of high-voltage electrical products for domestic manufacturers. At the same time, it undertakes more and more product testing entrusted by foreign manufacturers. The new test loop system of the large-capacity laboratory under construction will have the comprehensive test capability of 550kV/63kA full-pole, 800kV/63kA 1/2-pole circuit breaker and 500 kV DC converter valve, and the laboratory level of Gaoxi Institute has reached the international first-class level.
Xigaosuo Company is the research center of high-voltage electrical products development and AC /DC system in China. It has the latest imported real-time simulation device and computer simulation program to study AC /DC transmission engineering system. The 3 ~ 550 kV high-voltage switchgear designed and developed by Gaoxiyuan Company has been widely used in electric power, metallurgy, chemical industry, electrified railway, urban power grid transformation and rural power grid transformation. According to incomplete statistics, at present, the annual output value of products designed and jointly developed by Gaoxiyuan in China high-voltage switchgear industry reaches several billion yuan.
Gaoxiyuan is a member of International Electrotechnical Commission (IEC), International Conference on Large Power Grid (CIGRE) and International Short Circuit Test Organization (STL), and is the domestic centralized unit of IEC TC 17 and other related technical committees. Since its establishment, Gao Xi Company has been committed to the development of high-voltage electrical products in China, and constantly seeks exchanges and cooperation with international counterparts, and has good cooperative relations with KEMA test station, CESI test station, KERI of South Korea, TERTEC of Taiwan Province, etc. The secretaries-general of China Electrical Appliance Industry Association High Voltage Switch Branch, National High Voltage Switch Standardization Committee and National High Voltage Technology and Insulation Coordination Standardization Committee are all affiliated to Gao Xi Institute.
