In the era of the Global Energy Transition, the reliability of power grids is paramount. Jiangxi QOCI Electric Co. Ltd (江西泉新), established in 2002, stands at the forefront of this industrial shift. With a registered capital of 508 million Yuan, we specialize in high-strength toughened glass insulators that serve the backbone of world-class power grids.
Our commitment to "Innovation, Quality, and Service" ensures that ultra-high voltage (UHV) and extra-high voltage (EHV) lines remain operational under extreme environmental stress, from desert sands to saline coastal fog. We actively participate in the construction of green energy infrastructure globally.
China's insulator technology has reached full maturity. QOCI Electric contributes to this legacy by exporting high-performance disc suspension glass insulators that meet and exceed IEC 60305 standards, supporting international EPC projects and national utility tenders across five continents.

Advanced engineering tailored for specific environmental and mechanical challenges.
From the high-altitude plateaus to humid tropical regions, our insulators are engineered with specific leakage distances to prevent pollution flashover. Our "Anti-fog" and "Open profile" designs are essential for coastal and desert installations.
Supporting AC and DC transmission lines, our products like the U550B and U210B series provide the mechanical strength and dielectric integrity required for heavy-duty transmission towers.
We provide specialized ground-wire insulators and RTV silicone-coated glass insulators for areas where manual cleaning is impossible, reducing maintenance costs significantly.
Designed with shallow ribs for effective self-cleaning by wind or rain. Exceeds IEC 60305 leakage distance values.
Features long, widely-spaced under-ribs. Crucial for coastal areas to prevent salt fog bridging.
Marked by the absence of under-ribs to avoid accumulation of industrial dust or desert sand.
Combines the mechanical strength of glass with the hydrophobicity of silicone. The ultimate low-maintenance solution.
Key for UHV lines. Three layers of discs provide exceptional creepage distance and flashover resistance.
Guides lightning current safely to the earth, protecting expensive grid equipment from surge damage.
Our factory in Pingxiang utilizes total oxygen kilns and automated forming presses to ensure glass purity and structural consistency. Every insulator undergoes rigorous High Voltage Testing and Mechanical Load Verification before shipment.
We understand that different regions require specific compliance (ANSI, IEC, BS, AS). QOCI provides comprehensive technical documentation, FAT (Factory Acceptance Test) support, and localized logistics optimization to ensure project timelines are met.
As smart grids become the standard, QOCI Electric is investing in Digital Twin integration and Smart Monitoring capabilities for insulators. Our future roadmap includes the development of sensors embedded in hardware components to monitor real-time mechanical stress and leakage currents, providing predictive maintenance data to grid operators. This "Information Gain" approach ensures that we are not just a manufacturer, but a technology partner in power stability.
