Discover our elite tier of IEC-compliant suspension, anti-pollution, and fog-type glass insulators engineered for robust reliability.
As global energy transition accelerates towards Ultra-High Voltage (UHV) and Extra-High Voltage (EHV) networks, the demand for resilient anti-pollution components has surged exponentially.
Modern electrical transmission faces unprecedented challenges from urbanization and heavy industrial pollution. Fog type insulators provide critical creepage distance expansion, preventing flashovers in coastal and humid high-salt environments.
Built strictly under IEC, ANSI, and GB guidelines, our manufacturing ecosystem ensures uncompromised electrical stability. Every batch undergoes stringent electromechanical destructive testing before global deployment.
Active participant in worldwide sustainable energy grids. Our toughened glass solutions offer exceptional self-cleaning performance, lowering lifetime operational and maintenance expenditure for utility providers.

State-of-the-art thermal processing delivering superior toughened glass crystallization and internal stress management.
Expert insights into selecting, installing, and maintaining high-voltage fog-type insulators.
Fog type insulators feature extended under-ribs and a high creepage distance to surface ratio (often exceeding 3.2). This geometry prevents solid contaminant bridging and facilitates natural self-cleaning via wind and rain, drastically reducing flashover risks in coastal and industrial environments.
Yes. All products manufactured by Jiangxi QOCI Electric Co. Ltd strictly adhere to IEC 60305, IEC 60383, ANSI C29, and GB standards, verified by certified high-voltage laboratory testing.
Toughened glass provides instant visibility of damage upon shattering (self-shattering safety feature), eliminating the need for complex field testing tools. It also exhibits superior resistance to thermal shock and mechanical fatigue.
