132kV Horizontal Line Post Insulators
Rated Voltage: 132 kV
Specified Mechnical Load: 6.5 kN
Standard: IEC 61952
Brief Introduction
The 132kV post type horizontal insulators are made of high-grade by Chinese composite line post insulators manufacturer Xiangyang Guowang, HTV silicone rubber, suitable for the pole or tower of power grid.
The 132kV post type horizontal insulators consisting of a load-bearing cylindrical insulating solid core, a housing and end fittings attached to the insulating core. It is intended to be subjected to cantilever, tensile and compressive loads.
Eed-fittings are made of ductile iron. And all ferrous parts, except stainless steel and aluminium shall be galvanized. And Integral component or formed part of an insulator intended to connect it to a supporting. The top clamp for the conductor to be used for the transmission line are made of aluminium alloy.
