As the world pivots towards a decarbonized energy landscape, the reliability of high-voltage transmission lines has never been more critical. Jiangxi QOCI Electric Co. Ltd, founded in 2002 with a registered capital of 508 million Yuan, stands at the forefront of this industrial revolution. From our 70,000 m² state-of-the-art facility in Jiangxi Province, we engineer the U210B series—a flagship 210kN mechanical strength toughened glass insulator designed for the most demanding environments on Earth.
High-capacity production ensuring stable supply for national grid projects worldwide.
A specialized R&D team focused on advanced dielectric materials and aerodynamic design.
Pioneering innovations in RTV silicone coatings and anti-pollution profile designs.
The U210B (specifically standard type U210B and anti-fog type U210BP) represents a critical mechanical threshold for ultra-high voltage (UHV) and extra-high voltage (EHV) lines. A mechanical failing load (MFL) of 210kN allows for longer spans, fewer towers, and greater resilience against environmental loading such as ice accumulation and high-velocity wind gusts. Our U210B units are manufactured using a specialized thermal toughening process that creates high compressive stress on the glass surface, rendering the units nearly immune to electrical puncture and age-related degradation.
The global insulator market is undergoing a seismic shift. Procurement directors at utility companies like National Grid, EDF, and State Grid are increasingly favoring Toughened Glass over Porcelain or Composite for long-term transmission assets. Why? The "Self-Shattering" property of toughened glass serves as a built-in visual inspection tool, drastically reducing maintenance O&M costs.
Increasing demand for glass insulators in High-Voltage Direct Current (HVDC) links for cross-border power sharing.
Coastal and industrial zones now mandate Anti-Fog (U210BP) profiles with specific leakage distances exceeding 3.2 ratios.
Hybrid solutions combining glass mechanical strength with RTV (Room Temperature Vulcanization) silicone hydrophobicity.
Jiangxi QOCI Electric provides comprehensive solutions for diverse grid challenges. Our Aerodynamic Type insulators are designed for desert regions where wind and sand storms are prevalent, preventing solid pollution buildup. For heavy industrial areas, our Triple-Shed and Double-Shed designs provide the necessary creepage distance to prevent pollution flashover—one of the leading causes of unplanned grid outages.
Navigating international standards is a core competency. Our U210B products strictly adhere to IEC 60305, IEC 60383, and ANSI C29 series standards. We understand that "Quality" is a responsibility. Every batch undergoes rigorous testing, including thermal shock tests, steep front-of-wave impulse tests, and mechanical load-time tests to ensure 100% grid integrity.
