Ceramic suspension insulator can be divided into common suspension insulator and anti-pollution suspension insulator according to pollution status of enviroment. Anti –pollution U70BS ceramic suspension insulator has long term life.
As the name suggests, the suspension type insulators are mounted on the cross-arm on the pole. There is a groove on the upper end of the insulator. The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor. Suspension insulators are used for transmission and distribution of electric power at voltages up to 1000 kV.
