Jiangxi QOCI Electric Co. Ltd, founded in 2002 with a registered capital of 508 million Yuan, stands as a beacon of Chinese manufacturing excellence. Located in the Pingxiang Industrial Park, our 70,000 m² facility is dedicated to engineering the world's most reliable high-voltage insulators.
The U160BLD Glass Isolator represents the pinnacle of high-tensile glass insulation technology, specifically engineered for 220kV to 500kV AC and DC transmission systems. As a critical component in "Cap and Pin" type suspension strings, the U160BLD offers a nominal electromechanical failing load of 160kN, ensuring structural integrity under extreme mechanical stress and environmental fatigue.
Unlike porcelain insulators, the U160BLD toughened glass variant offers a unique "Self-Shattering" property. When the dielectric strength is compromised, the glass shell shatters into small, non-dangerous fragments, while the internal stub retains its full mechanical strength. This allows maintenance teams to perform "Ground-based Visual Inspections" without needing complex diagnostic tools, significantly reducing OpEx for utility providers.
Our U160BLD units use low-expansion borosilicate glass, melted in total oxygen kilns to eliminate inclusions that cause spontaneous breakage.
160kN rating accommodates high-wind spans and heavy ice loading, common in North American and Northern European grids.
Maintains zero-puncture probability, ensuring that the insulator string remains operational even in the event of a surface flashover.
In regions like Southeast Asia and Middle Eastern coastlines, the Anti-Fog Profile of the U160BLD series (including variants like the U120BLP) is essential. The deep under-rib design extends the creepage distance, preventing salt-spray flashovers.
For projects in Sub-Saharan Africa or the Atacama Desert, our Open Profile/Aerodynamic designs prevent sand accumulation, leveraging natural wind cleaning to maintain insulation performance without manual intervention.
We provide factory-applied Room Temperature Vulcanization (RTV) silicone coatings on our glass isolators. This hybrid approach combines the mechanical reliability of glass with the hydrophobicity of polymers, ideal for the world's most polluted industrial corridors.
As a leading U160BLD Manufacturer, our factory in Jiangxi integrates the entire production vertical—from raw silica sourcing to zinc-coating of caps.
