In the global energy landscape, China has emerged as the definitive hub for high-voltage insulation technology. Our facility in Luxi County, Pingxiang, Jiangxi Province—the renowned "Electric Porcelain Capital"—leverages a mature industrial ecosystem to provide Information Gain to our global partners.
With a plant area exceeding 70,000 m² and an annual output of 39,000 tons, our factory ensures supply chain stability for mega-projects, from HVDC lines to local distribution networks.
Supported by 53+ engineering technicians and 26+ invention patents, we push the boundaries of toughened glass durability and electrical performance.
Utilizing state-of-the-art oxygen-fuel combustion kilns reduces defects and improves the homogenization of glass, resulting in the "Zero Puncture" reliability required by modern grids.
Founded in Dec. 2002, with a registered capital of 508 million Yuan, QOCI Electric has dedicated itself to serving world-class power grids. We actively participate in green energy construction, ensuring grid safety through rigorous quality control and innovation.
As countries shift to Ultra-High Voltage (UHV) transmission to minimize line losses, the demand for glass insulators with mechanical strengths up to 550kN (like our U550B) is skyrocketing. Our insulators are designed to withstand the harmonic vibrations and electrical stresses of smart grids.
Environmental concerns are driving the adoption of RTV Silicone-coated Glass Insulators. These offer the mechanical strength of glass with the hydrophobicity of polymers, reducing maintenance costs in high-pollution zones.
Extreme weather events require insulators that can handle sudden temperature swings and high wind loads. Toughened glass is naturally resistant to thermal shock compared to traditional porcelain.
Leakage distance exceeds IEC 60305 values. Designed with shallow, well-spaced ribs for effective self-cleaning by wind and rain.
Characterized by long, widely-spaced under-ribs to avoid arc bridging. Ideal for coastal (salt fog) and high-pollution industrial zones.
No under-ribs to prevent sand and dust accumulation. Solves ice-bridging problems in extreme climates.
Features two external ribs for maximum pollution resistance and ease of manual cleaning in saline soil areas.
A key component for UHV lines. Three layers of umbrella discs provide longer creepage distance and superior flashover resistance.
Eliminates the need for regular washing. Increases surface hydrophobicity to minimize leakage currents in heavy pollution.
Salt spray is highly conductive. Our anti-pollution glass insulators prevent corrosion and flashover in offshore wind farms.
Sand accumulation causes tracking. The aerodynamic "Open Profile" ensures sand particles bypass the dielectric surface.
Cement dust and chemical soot are neutralized by the self-cleaning properties of toughened glass and RTV coatings.
Low air pressure reduces insulation strength. Our triple-shed designs compensate by increasing the total arc distance.
