Serving world-class power grids with high-performance glass insulation technology. Actively participating in the construction of green energy pathways and UHV DC/AC systems.
Responsibility is our guarantee. Every U70BLP unit undergoes rigorous hydraulic, thermal, and electrical tests to ensure 50+ years of operational life.
Providing end-to-end technical support for global utilities. From local site assessment to specialized RTV coating services for extreme environments.
The U70BLP Glass Insulator represents a pinnacle of electrical engineering, specifically designed to address the challenges of pollution flashover in high-voltage transmission lines. As global power demands shift toward decentralized renewable sources, the need for robust, low-maintenance insulation has never been greater. Our U70BLP series, manufactured in our state-of-the-art Jiangxi facility, provides the mechanical strength of 70kN coupled with a specialized anti-pollution profile that ensures stability in salt-fog, industrial dust, and high-humidity environments.

The U70BLP (146/320/550) profile features an extended creepage distance of 550mm, preventing the formation of conductive layers in high-salinity coastal environments.
Designed with deep under-ribs, these insulators resist the accumulation of conductive fly ash and chemical particulates common in heavy industrial corridors.
Our Aerodynamic profiles (Open Profile) allow wind to naturally "self-clean" the glass surface, preventing sand accumulation and reducing corona discharge at high altitudes.
QOCI Electric is currently pioneering the next generation of "Smart Insulators." Our roadmap includes:
Located in the heart of China’s electrical industrial park in Luxi, Jiangxi, Jiangxi QOCI Electric Co. Ltd (founded in 2002 with 508 million Yuan capital) leverages a vertically integrated supply chain. Our "Total Oxygen Kiln" technology is a critical advantage, providing:
Total Oxygen combustion reduces carbon emissions by 40% compared to traditional kilns while ensuring a more homogeneous glass melt.
Our proximity to high-grade silica sources allows for strict control over raw material purity, resulting in glass with superior dielectric strength.
With an annual output of 39,000 tons, we maintain a buffer stock of standard U70BLP units, ensuring lead times are 30% faster than the industry average.
Our products are engineered to meet and exceed international standards including IEC 60305, ANSI C29.2B, and ISO 9001. We provide localized support for utility tenders across Africa, South America, and Southeast Asia.
