      XIAMEN JIAHUA ELECTRIC POWER TECHNOLOGY CO., LTD.

      Xiamen Jiahua Electric Power Technology Co., Ltd. was established in 2003 and is located in the scenic Xiamen National High-tech Entrepreneurship Center - Xiamen Torch High-tech Zone Pioneer Park. It is a Sino-foreign joint venture national "high-tech" enterprise and a national "specialized and new" small giant enterprise. In recent years, it has received various honors and awards from the Ministry of Science and Technology of the People's Republic of China, Fujian Provincial Science and Technology Department, Xiamen Science and Technology Bureau, local governments, and the power industry. The company focuses on the research and development, production, sales and technical services of internal fault detection products for electrical equipment, and has a group of high-quality scientific research and technology backbones. The founder of the company is a professor-level senior engineer, who has been engaged in the quality supervision and fault diagnosis of transformers and SF6 electrical equipment for a long time. He was hired by the National Standardization Management Committee as a consultant of the "National Electrochemical Standardization Technical Committee", and was the first to conduct research and product development of SF6 electrical equipment decomposition products in China.

      Our company has independently developed and produced JH series SF6 decomposition detectors, purity meters, dew point meters, SF6 gas comprehensive testers, SF6 gas density relay calibrators, SF6 leak detectors, SF6 mixed gas detectors, SF6 and mixed gas distribution recovery and filling device series, new environmentally friendly insulating gas (C4F7N, clean air, etc.) comprehensive detectors, C4F7N leak detectors, CO2 leak detectors, infrared temperature measuring imagers, acoustic wave imagers, chromatographs, partial discharge devices, gas distribution meters, sampling devices and other laboratory and field portable instruments, as well as SF6 decomposition products online, SF6 gas leakage alarm, SF6 micro-water density, partial discharge, dissolved gas in transformer oil, etc., for the fault diagnosis and Equipment operation and maintenance provides a favorable means.

      For many years, our company has been leading the industry in the application of decomposition products to diagnose internal faults of SF6 electrical equipment, actively promoting the development of this technology, and has been recognized and recommended by State Grid Corporation, China Southern Power Grid Corporation and major power generation groups. Participated in power supply protection tasks for major post-disaster power rescue and important conferences and activities for many times. For example, after the Wenchuan earthquake in Sichuan in 2008, the devastating floods in Henan in 2021 and the Jishi Mountain earthquake in Gansu in December 2023, participated in the investigation of hidden dangers in the power grid after the disaster; participated in the 2008 Beijing Olympic Games, the 2016 G20 Hangzhou Summit and the 2017 Xiamen BRICS Summit, the 2022 Beijing Winter Olympics, the 2023 Hangzhou Asian Games and other major conferences and sports events, and assisted in the investigation of hidden dangers of safety risks; Most of the national and local competition tests organized by the State Grid and the South Grid used our SF6 comprehensive detector and achieved excellent results. In 2020, our company helped the State Grid substation operation and maintenance skills competition, and the JH6000D-4 synthesizer was the only SF6 gas analyzer designated as the "GIS gas chamber diagnosis and analysis" competition project; this product is also the designated training instrument for the State Grid substation operation and maintenance youth rotation training from 2021 to 2024. Our company provides technical support for the national substation operation and maintenance work, excellent product performance and professional technical services, and has been unanimously recognized by all coaches and students.

      Over the past few years, our company has been effective in the diagnosis and analysis of GIS gas chambers, detecting more than 300 faulty equipment, avoiding many accidents for the hidden dangers detected during operation. The company's products are now widely used in power systems, switchgear factories, rail transit, metallurgy, petrochemical and other industries in 31 provinces and autonomous regions across the country, and are also exported to South East Asia and other countries. So far, it has produced and sold more than 1,000 sets/set of instruments and equipment, which has won unanimous praise from the majority of users, accumulated rich experience and a large number of fault diagnosis cases, which have become the basis for the formulation of regulations and standards, and have been included and published by China Electric Power Publishing House.

      Our company attaches great importance to the construction of intellectual property system, and has established industry-university-research cooperation with many institutions of higher learning and scientific research units, and has achieved remarkable results. So far, our company has declared 66 national patents and authorized 46. Our company also actively participates in the preparation, revision and review of national, industry, group and enterprise standards. At present, we have completed and participated in the preparation and test verification of nearly 20 standards, etc., contributing to the development of the industry. Jiahua wisdom!
