Product details

220kV Polymer Suspension Insulators

Polymer suspension insulator FXBW-220/160 is used for overhanging and tension-resistant overhead lines and substations with rated voltages of 10~330kV and frequencies not exceeding 100Hz in ordinary and dirty AC power systems. It is especially suitable for polluted areas and can effectively prevent pollution flashover. It is widely used as a substitute for porcelain insulator at present.
