Founded in December 2002, Jiangxi QOCI Electric Co. Ltd has established itself as a cornerstone of the global power grid infrastructure. With a registered capital of 508 million Yuan and a sprawling 70,000 m² industrial park in Pingxiang, Jiangxi Province—the renowned "Insulator Capital of China"—we provide world-class insulation solutions that power the future.
Our commitment to Innovation, Quality, and Service drives us to actively participate in green energy construction and ensure the safety of ultra-high voltage (UHV) transmission lines across continents.
The U70BLP anti-pollution glass insulator represents the pinnacle of modern dielectric engineering. Designed specifically for high-contamination environments, the "P" designation signifies a profile optimized for pollution flashover resistance. With technical parameters typically reaching a leakage distance of 450mm to 550mm, these units provide a 30% increase in creepage distance compared to standard profiles.
China currently produces over 70% of the world's toughened glass insulators. At QOCI Electric, our advantage is built on four pillars:
As global energy demand shifts toward renewables, transmission lines are moving into harsher terrains—offshore wind farms, high-altitude plateaus, and desert solar parks. This drives the demand for:
High salinity causes rapid corrosion and conductive film formation. The U70BLP’s wide-spaced ribs allow wind and rain to naturally wash away salt deposits, maintaining high insulation resistance.
In areas with heavy coal-fired power plants or chemical industries, solid pollution builds up. The "Anti-Fog" profile of the U70BLP prevents arc bridging between adjacent sheds.
Aerodynamic profiles (Open type) are critical here. We provide solutions that minimize sand accumulation, which otherwise acts as a moisture trap for early-morning dew flashovers.
For international procurement officers and grid engineers, QOCI Electric ensures full compliance with global standards:
Standardized dimensions for suspension insulators, ensuring interchangeability in existing grid strings.
Meeting North American requirements for mechanical strength and wet/dry flashover voltages.
ISO 9001, 14001, and 45001 certified manufacturing processes for environmental and occupational safety.
