Product Description
U120B Model Glass Disc Insulator with 127mm Spacing and 320mm Creepage Distance for High Voltage Transmission
The U120B glass insulator is a high-performance disc insulator with a minimum mechanical breaking load of 120kN. Designed for demanding applications, multiple U120B glass insulators can be connected in series to form suspension insulator strings, making them ideal for high-voltage transmission lines up to 330kV.
Available Configurations
- Standard Profile: For general transmission line applications
- Anti-pollution Profile: Enhanced performance in contaminated environments
- Aerodynamic Profile: Optimized for high-wind conditions
