Chinese insulation resistance tester industry

The Chinese insulation resistance tester industry has accelerated its overseas expansion in the past decade, shifting from exporting low-end equipment to systematic output of 'technology+standards+services'. In 2025, the market size of the industry will reach 1.286 billion yuan, with an average compound annual growth rate of more than 7%. The export volume will achieve explosive growth in countries along the 'the Belt and Road', and the export volume of some testing equipment will increase by more than 300% year-on-year. Core enterprises such as Wuhan Guodian Xigao, Shanghai Guoshi Electric Power, and Dawan Defu have products that cover more than 60 countries in Europe, America, Southeast Asia, the Middle East, and Africa. They have passed international certifications such as CE, FCC, ROHS, IEC 61010-1, and IEEE Std 43-2013, with test voltages covering 250V-10kV and a protection level of IP65, accurately meeting the harsh working conditions of global high-voltage power grids, photovoltaic power stations, rail transit, and other industries. The UT575A and other intelligent models of Youlide integrate Bluetooth, USB data direct transmission, and PI/DAR automatic diagnostic functions, deeply embedded in overseas EPC projects, achieving a three in one output of 'equipment+detection standards+operation and maintenance support'. The industry is transitioning from 'Made in China' to 'Chinese Standards', and insulation resistance testers have become one of the most representative high-end instruments in the field of power safety.
