Top-tier components for UHV, EHV, and standard transmission networks.
In the modern electrical landscape, the demand for high-voltage transmission stability has never been greater. As global energy consumption shifts towards renewable sources—often located in remote, harsh environments—the role of toughened glass insulators has become critical. Unlike traditional porcelain, tempered glass offers visual self-diagnostic capabilities; a damaged glass shell will shatter into small fragments, making aerial inspection efficient and reliable.
Jiangxi QOCI Electric Co. Ltd, established in 2002, sits at the forefront of this technological shift. With a registered capital of 508 million Yuan, we have optimized our manufacturing processes to meet the stringent demands of IEC, ANSI, and AS standards. Our focus on Information Gain means we don't just sell products; we provide engineered solutions for the world’s most challenging grid environments.

Specialized designs for specific atmospheric and electrical stressors.
Our standard profiles feature leakage distances exceeding IEC 60305 requirements. The shallow, well-spaced ribs facilitate natural self-cleaning by wind and rain, minimizing maintenance in temperate zones.
Characterized by deep, widely-spaced under-ribs, this design prevents arc bridging in high-salt fogs or coastal environments. With a leakage distance/spacing ratio of 3.2, it is the industry standard for humid, polluted areas.
For extreme pollution, our Room Temperature Vulcanization (RTV) silicone coating adds hydrophobicity to the mechanical strength of glass. This eliminates the need for periodic manual washing in industrial zones.
Located in the Luxi Industrial Park, Pingxiang, Jiangxi Province—often cited as the "Insulator Capital of the World"—Jiangxi QOCI Electric leverages a mature local ecosystem. Our supply chain advantage is built on three pillars:
We combine Chinese manufacturing speed with international quality standards, ensuring that procurement managers can meet tight project deadlines.
From desert heat to arctic frost, our insulators are engineered for local conditions.
Open profile designs prevent sand accumulation and ice-bridging in arid regions.
Designed for voltages up to 1000kV AC and ±800kV DC, supporting massive energy transfers.
Double and Triple-shed types provide extended creepage distances to combat chemical pollution.
Corrosion-resistant metal fittings paired with toughened glass withstand salt-spray conditions.
Reliability is guaranteed through systematic laboratory validation.
Our facility houses state-of-the-art testing equipment including High Voltage Test Labs, Mechanical Load Testers, and Thermal Shock Chambers. Each unit must pass visual and electrical tests before dispatch to ensure 100% reliability in the field.
