Founded in December 2002, Jiangxi QOCI Electric Co. Ltd has emerged as a cornerstone of China's high-voltage infrastructure industry. With a registered capital of 508 million Yuan and an expansive 70,000 m² state-of-the-art facility in Pingxiang, Jiangxi Province, we combine decades of manufacturing expertise with aggressive R&D.
Our commitment to the E-E-A-T principle (Experience, Expertise, Authoritativeness, and Trustworthiness) is evidenced by our 26+ national patents and an annual output exceeding 39,000 tons of high-strength glass insulators. We serve as a strategic partner for world-class power grids, participating in the critical construction of green energy corridors globally.
The transition from standard profiles to "External Shed" and "Triple-Shed" designs is driven by the need for higher creepage distances in coastal and industrial areas. These designs minimize leakage current and prevent flashovers.
With the rise of Ultra-High Voltage (UHV) transmission, insulators must now withstand 800kV to 1100kV DC/AC. Our toughened glass offers superior mechanical stability under these extreme electrical stresses.
Room Temperature Vulcanization (RTV) silicone coatings on glass insulators are the new gold standard, combining the mechanical reliability of glass with the hydrophobicity of composites.
The External Shed Profile is specifically engineered for environments plagued by solid pollution (dust, sand, industrial particulates). Unlike traditional under-rib designs which can trap contaminants, the external shed facilitates aerodynamic self-cleaning. In regions with frequent sandstorms or industrial smog, this design reduces maintenance cycles by up to 60%, providing a significant "Information Gain" for grid operators focused on lifecycle cost reduction.
Our solutions are categorized by terrain: Desert (Open Profile), Coastal (Anti-Fog), and Industrial (External Shed). This ensures maximum reliability from the Sahara to the North Sea.
Strict adherence to IEC 60305, ANSI C29, and BS standards. Every unit undergoes high-voltage testing and mechanical fail-safe verification before shipment.
Geographic Scenarios

Functional Grid
Special Industry
Leakage distance exceeds IEC 60305 values. Shallow ribs for natural self-cleaning by wind/rain.
Deep under-ribs for coastal salt-fog environments. High leakage/spacing ratio (~3.2).
Marked by the absence of under-ribs. Specifically for desert areas with high sand accumulation.
Connects internal metal accessories to grounding, guiding lightning current safely to the earth.
Our manufacturing process utilizes the "Total Oxygen Kiln" technology, which ensures a more homogeneous glass melt, significantly reducing the probability of spontaneous shattering. This is a critical factor for utility companies looking for long-term reliability.
As we move toward 2030, Jiangxi QOCI Electric is investing in Smart Insulator Sensors that monitor real-time leakage current and ambient humidity, feeding data back to central grid control. Our "Green Factory" initiative also focuses on reducing carbon emissions during the glass melting process, aligning with global ESG requirements for power equipment manufacturers.
