History

On February 1, 2013, Xi'an Xu&hui Electromechanical Technology Co., Ltd. was established.

In 2014,  the second-generation demagnetizer was launched, which quickly and thoroughly solved the residual magnetism problem of 750kV transformers. Successfully passed IS09001 quality system certification and Ce certification.

 In 2015,  we moved to a 600 square meter plant to solve the problem of on-site calibration of 1000kV lightning arrester monitors.

 In 2016,  the problems of large energy loss and difficult waveform analysis in cable fault detection were solved and an invention patent was obtained.

In 2017,  it was awarded the National High-tech Enterprise, and products were exported to more than ten countries and regions.

In 2018,  1SO 9001 Quality Management and ISO 14001 Environmental Management and ISO45001 Occupational Health successfully passed , and obtained the third-level qualification for general contracting of electric power and the fourth-level qualification for installation (repair and testing)

In 2019,  a self-owned and independent plant of 3,000 square meter. Smoothly carried out 220kV, 750kV and 1000kV special adjustment and maintenance test projects.

In 2020, Ubiquitous power detection platform, various cable fault simulation platforms were established, and "JJ Machinery 1042-2020 Cable Fault Tester Calibration Specification" was drafted and successfully passed

In 2021,  a 10kV and 110kV cable fault training system was established in a certain power school. Oscillating wave partial discharge and ultra-low frequency dielectric loss detection projects were promoted.

In 2022,  Successfully delivered several military cable inspection vehicles. Products are exported to more than 50 countries and regions.

In 2023,  Successfully passed the A-level of the integration of information and industrialization management system, participated in the revision of "D.L/T849.4-2004 "General Technical Conditions for Special Test Instruments for Power Equipment Part 4 Ultra-low Frequency High Voltage Generator"" and successfully passed it.
