GW27-252/363/550 Disconnector

Description

Brief Description


GW27-252/363/550 HV disconnectors are developed by Pinggao based on the same kind of domestic and foreign products, with rated voltage from 110 kV to 550 kV and rated current from 2000 A to 5000 A. This series of products are three-column horizontal-rotation style, with the world-class performance and anticorrosive capacity. In main blade system, the movement of conducting tube is a kind of composite action that horizontal move combines with axial rotation, which decrease the operating moment of force for the opening and closing. The operation of earthing switch is stable and reliable with simple structure.

Main Features

1  Integral structure of earthing blade is simple with reliable performance.

2  The base of porcelain insulator is welded and hot-galvanized with excellent anti-corrosive capacity. And the spring of earthing blade is not only insulated, but enclosed completely to enhance anti-corrosive performance.

3  Mechanical interlocking structure is simple and reliable.
