Good News | Industry Breakthrough & Recognition of Strength — Herch Opto Electronic Technology Co.,Ltd. Wins Its First Bid for Gallium Arsenide Fiber-optic Temperature Measurement Products in Hydropower Sector

Herch Opto Electronic Technology Co.,Ltd.’s Gallium Arsenide (GaAs) fiber-optic temperature measurement products have won their first bid in the hydropower sector.

        Recently, Herch Opto Electronic Technology Co.,Ltd. has successfully won the bid for the "Three Gorges Power Station VGS Unit Water-to-Air Stator Fiber-optic Temperature Measurement Project" of Dongfang Electric Machinery Co., Ltd., a subsidiary of Dongfang Electric Corporation. The company’s core product — gallium arsenide (GaAs) fiber-optic temperature measurement devices, specially designed for water turbine unit temperature monitoring, has achieved a breakthrough in the application scenario of large hydro-generator units. This marks the first application of the company’s products in the hydropower industry, and the robust strength in the fiber optic sensing field has won high recognition from leading industry clients.

        Targeting industry pain points of hydro-generator units, such as strong electromagnetic interference on stators, long temperature measurement distances, narrow installation clearances, and difficult replacement of faulty sensors, the solution leverages the core gallium arsenide (GaAs) optical fiber sensing technology to realize online temperature monitoring of stator windings. Featuring high measurement accuracy and strong anti-interference capability, it is adaptable to complex working conditions. This project builds a solid "sensing defense line" to ensure the safe and stable operation of large hydro-generator units.

        The Three Gorges Power Station is one of the world’s largest hydropower stations in terms of installed capacity, a veritable "national treasure project". Dongfang Electric Machinery is a leading enterprise in China’s power generation equipment industry. This cooperation represents high recognition from Dongfang Electric of Herch Opto’s technical strength and product reliability. Previously, the company has passed Dongfang Electric’s rigorous assessment and obtained the qualification as an approved motor supplier of Dongfang Electric Corporation. This successful bid is more than merely an order; it marks an important business breakthrough of Herch Opto’s gallium arsenide (GaAs) fiber-optic temperature measurement technology in the hydro-generator unit sector, laying a solid foundation for the company’s further exploration in the hydropower equipment market.

        From new application scenarios to new industry markets, Herch Opto Electronic Technology Co.,Ltd. consistently pushes boundaries with its core technologies. Going forward, Herch Opto will continue to refine more core sensing technologies, empower the intelligent upgrading of hydropower equipment, and contribute to the development of the new-type power system!
