On June 12, 2025, Jiangxi Huayao Electric Co., Ltd. achieved a significant milestone by successfully winning the glass insulator project tendered by SONELGAZ-TOS SPA in Algeria, with a contract value of approximately 11 million US dollars. This landmark cooperation not only marks Huayao Electric’s in-depth penetration into the North African power infrastructure market but also testifies to its outstanding strength in the global electrical insulation industry.
SONELGAZ-TOS SPA (Sonelgaz Transmission and System Operator SPA), a core subsidiary of Sonelgaz—the national electricity and gas group of Algeria—is the official operator and dispatcher of the country’s high-voltage transmission system. Tasked with the construction, operation, maintenance, scheduling and public bidding of transmission networks nationwide, it stands as a benchmark client in North Africa’s power infrastructure sector. Securing this bid has garnered widespread attention in China’s electrical porcelain industry, serving as a strong recognition of Jiangxi Huayao Electric’s advanced manufacturing capacity, strict quality control and reliable product performance.
Fully aware of the harsh desert conditions in Algeria, Jiangxi Huayao Electric Co., Ltd tailored high-performance glass insulators specifically for the local working environment. These customized products boast excellent high-temperature resistance, sand-dust resistance and anti-aging properties, enabling stable long-term operation under extreme conditions—including extreme dryness, intense sandstorms and strong UV radiation. By effectively reducing the risk of pollution flashover, the insulators provide a solid guarantee for the safe and stable operation of power grids in desert areas.
Transmission lines in the Sahara Desert are constantly challenged by harsh environmental factors: intense solar radiation, severe sand erosion, extremely dry air and drastic day-night temperature differences. Such conditions place extremely high demands on the weather resistance, anti-pollution performance and mechanical stability of insulators. Rising to the occasion, Jiangxi Huayao Electric Co., Ltd completed the full delivery of all products in just four months, demonstrating its efficient execution capabilities and winning high praise from SONELGAZ-TOS SPA for its professionalism and reliability.
Currently, the batch of glass insulators has been officially installed in relevant power projects in Algeria and is operating stably and excellently, further verifying the superior quality and adaptability of Huayao Electric’s products in harsh environments.
Looking ahead, Jiangxi Huayao Electric Co., Ltd. will adhere to its commitment to quality and innovation, continuing to provide high-performance insulation products and one-stop professional services to customers around the world. It will focus more on meeting the specific needs of desert transmission projects in North Africa and Algeria, contributing to the development of the global power infrastructure industry with professional strength and reliable products.
