High-Strength Brown Glazed Porcelain Stay Insulator HV/MV Grade Anti-Pollution for Outdoor Power Transmission Lines

Jiujin Electric Power’s Brown Glazed Porcelain Stay Insulator represents traditional reliability combined with modern manufacturing excellence. Crafted from high-alumina porcelain with a durable brown glaze finish, this insulator provides superior resistance to environmental pollution, UV radiation, and extreme weather conditions. The smooth, glazed surface prevents pollutant accumulation and facilitates natural cleaning during rainfall, maintaining consistent electrical performance in contaminated environments. With excellent mechanical strength and dielectric properties, this stay insulator ensures secure guy wire support while preventing electrical leakage in transmission line systems. The robust construction withstands thermal shock and mechanical stresses, making it ideal for long-term outdoor applications in coastal, industrial, and high-altitude installations.
