1、 Overview
GW 5-40.5/GW5-126 Series outdoor high-voltage isolation switch It's a double column V U-shaped rotary disconnector, single break. Each phase has two insulating pillars, and the top of the insulating pillars is equipped with conductive poles.
The insulating pillar is rotated by the operating mechanism to drive the conducting pole to complete the opening and closing actions. The mechanical interlock device ensures the correct operation mode between the grounding switch and the disconnector.
2、 Main features
one Strong corrosion resistance. All exposed steel parts are hot-dip galvanized surface treatment The transmission part adopts stainless steel shaft pin , composite shaft sleeve, double arm Connector Universal ball bearings, press plate joints and other transmission connectors ensure accurate and reliable transmission, corrosion resistance, and meet the requirements of long-term reliability and practicality.
two Good conductivity. The contact between the outlet socket and the conductive pole is fixed by the soft connection structure, and the conductive performance is reliable; The contact piece is made of external pressure stainless steel Spring It can effectively avoid spring shunt, and has the characteristics of rust prevention and stable force value.
three The conductive rod is made of aluminum alloy, which has light weight, large heat dissipation area, high strength and good anti-corrosion performance. It is safe, reliable and maintenance free for long-term use.
four . The contact is formed by bending copper plate and assembled with the conductive rod for easy maintenance and replacement; During the opening and closing process, the friction stroke between the plate contact and the contact piece is short, and the operating force is small.
five The grounding switch can be installed on both sides of the base according to the user's needs.
