According to the China News Service on June 19, the operation test of the low-temperature environment power transmission and transformation equipment of the 220kV Mohe Substation was successfully completed. This test can provide core data for the safe operation of power transmission and transformation equipment of China's power grid under low temperature and harsh environment, which also fills the gap in China's technical research field.

     In 2011, "Experimental Research on Operation Technology of Transmission and Transformation Equipment in High Latitude Areas" was officially supported and approved by the State Grid Corporation of China. It was completed and put into operation on December 30. In July 2012, the low temperature environment transmission and transformation equipment test of Mohe Substation The room successfully passed the handover and acceptance.

     As a supplement to the UHV AC and DC test base of State Grid Corporation, the function of this laboratory is positioned to provide a full range of technical support for the operation and maintenance of power transmission and transformation equipment, equipment selection and performance testing in high latitudes and cold areas. Research on key technologies for ultra-high-voltage and ultra-high voltage transmission in high-cold conditions creates experimental conditions.

  The laboratory has the electrical performance test capability for voltage levels of 500 kV and below. A number of tests including 800 kV UHV resonance withstand voltage have been completed. Suzhou Huadian participated in the program design, equipment research and development, installation and commissioning of the laboratory. Provided outdoor installation, 800 kV frequency conversion series resonant complete set that can work at -45℃ extreme low temperature and special test vehicle for low temperature operation
