U120B glass insulator is a type of disc insulator with a minimum mechanical breaking load of 120kN. Multiple U120B glass insulators can be connected in series to form a suspension insulator string, making them suitable for high-voltage transmission lines up to 330kV.Depending on the installation environment, U120B glass insulators are available in three types: standard profile, anti-pollution profile, and aerodynamic profile, each designed to meet specific performance requirements under different conditions.
