VOBO Anti-Pollution Type Toughened Glass Insulator

The VOBO Anti-Pollution Type toughened glass insulator is specifically designed for use in areas with high levels of atmospheric contamination — including industrial zones, coastal regions, desert environments, and areas near chemical plants or mining operations. This series features an extended creepage distance profile optimized to prevent pollution flashover, one of the leading causes of transmission line outages in contaminated environments.

Key Specifications

• Mechanical Load Rating: 40kN to 300kN
• Applicable Voltage: 10kV – 1100kV transmission lines
• Pollution Level: Suitable for IEC pollution levels c, d, e (heavy to very heavy)
• Creepage Distance: Extended profile, significantly greater than standard type
• Material: Toughened borosilicate glass
• Standards: IEC 60305, IEC 60815, GB/T 7253

Key Advantages

• Pollution Flashover Prevention: Extended creepage distance with optimized umbrella profile prevents leakage current flashover even under heavy contamination
• Proven in Harsh Environments: Deployed across Middle East, Southeast Asia, and Chinese coastal and industrial transmission corridors
• Smooth Glass Surface: Inherently non-porous glass resists pollutant absorption better than porcelain alternatives
• Self-Cleaning Capability: Natural rainfall effectively restores insulation performance between contamination events
• Self-Destruction Defect Detection: Easy fault identification through glass self-destruction mechanism

Applications

High-voltage overhead lines in industrial areas, ports, coastal zones, desert corridors, and near chemical, mining, or cement plants. Suitable for IEC pollution severity classes c–e environments across 10kV to 1100kV systems.
