Suspension Insulators For High Voltage Overhead Line
|High voltage overhead line suspension porcelain
insulators are used for insulating and supporting conductors in high voltage overhead
transmission and distribution lines. They are usually connected into insulator strings
according to the voltage ratings of lines.
Theseseries of insulators are of normal type. They can be divided into five rating classes of 70,100,160,210,300kN,according to their electro-mechanical failing load.
Theinsulators correspond in all respects to GB1001 Suspension Porcelain Insulators for High Voltage Overhead Lines , Insulators coupling are in accordance with the specification of GB 4065 Orders in accordance with IEC standard are also available.
