In the contemporary energy landscape, the Glass Isolator U100bmp serves as a cornerstone for high-voltage (HV) and extra-high-voltage (EHV) transmission networks. As global power demand surges, particularly with the integration of renewable energy sources like wind and solar, the stability of the grid relies heavily on the mechanical and electrical integrity of suspension insulators.
China has emerged as the global leader in the manufacturing of toughened glass insulators, combining economies of scale with advanced material science. The U100bmp series, characterized by its 100kN electromechanical failing load, is specifically engineered to withstand the rigorous demands of 110kV to 500kV AC and DC lines. Industry analysts estimate that glass insulators now account for over 50% of new installations in high-pollution and high-humidity environments due to their superior "self-shattering" diagnostic feature, which simplifies maintenance compared to porcelain or composite alternatives.
Increasing urbanization in Asia and Africa is driving a double-digit CAGR for U100 series insulators in regional grid expansion projects.
UHVDC (Ultra High Voltage Direct Current) projects require insulators with extreme dielectric strength, where U100bmp excels.
Utilities are shifting toward glass due to the ease of visual inspection via drones, reducing O&M costs by up to 30%.
Founded in December 2002, Jiangxi QOCI Electric Co. Ltd has established itself as a premier global supplier of power equipment. With a registered capital of 508 million Yuan and a facility spanning 70,000 m², we represent the pinnacle of Chinese insulator manufacturing excellence.
Our commitment to "Innovation, Quality, and Service" ensures that every U100bmp unit leaving our factory meets the most stringent international standards, including IEC and ANSI.

The U100bmp Glass Isolator is not merely a piece of toughened glass; it is a sophisticated dielectric component. The manufacturing process involves a "Total Oxygen Kiln" for melting high-purity raw materials, followed by a precise tempering process that creates a prestressed outer layer. This results in an insulator that is virtually immune to thermal aging.

Designed with shallow, well-spaced ribs for effective self-cleaning by wind or rain. Ideal for areas with low pollution.
Characterized by deep ribs to provide extended leakage distance, preventing flashovers in industrial or coastal zones.
Coated with Room Temperature Vulcanization silicone to provide hydrophobic properties, minimizing leakage current.
Our products are engineered for diverse global environments, ensuring grid resilience from deserts to arctic tundras.
Coastal & Saline Areas: U100BLP models with high leakage distance resist salt-fog corrosion.
Industrial Hubs: Anti-fog profiles prevent accumulation of conductive dust and pollutants.
Desert Environments: Open profiles prevent sand accumulation and bridge-freezing.
UHV Transmission: Triple-shed designs used for stable performance in 800kV+ lines.
Precision hydraulic pressing ensures uniform glass thickness and density.
Every unit is subjected to steep-front impulse and power-frequency testing.
Advanced melting technology reduces impurities and enhances thermal shock resistance.
The next decade of insulator technology will be defined by Smart Grids and Material Innovation. At QOCI, our roadmap includes:
U100bmp glass insulators offer better thermal stability, higher mechanical strength-to-weight ratio, and a unique "fail-safe" property where damaged units shatter visibly, making them much easier and cheaper to inspect via ground teams or drones.
Our RTV (Room Temperature Vulcanization) silicone coating provides a hydrophobic surface that makes water bead off, carrying pollutants with it. This prevents the formation of a continuous conductive layer of moisture, drastically reducing flashover risks.
All our products are manufactured and tested in accordance with IEC 60305, IEC 60383, and ANSI C29 standards. We are ISO 9001 certified for quality management.
Yes, we offer specific DC models (U100BLP DC) with special glass compositions that resist ion migration and electrolytic corrosion, ensuring a service life of over 40 years.
