1. Product Overview 產品概述

The PGS-12kV Pole-Mounted Load Switch is a key switching device in the 12kV medium-voltage distribution network, mainly applied to outdoor overhead pole-mounted installation scenarios. It is designed to realize on-load switching of normal load current in the distribution line, and can quickly isolate the fault section when the line fails, effectively reducing the power outage range and improving the power supply reliability of the distribution network. The product integrates a vacuum arc-extinguishing unit, an operating mechanism, an insulation support and a shell into one, with a small volume and light weight, which is convenient for hoisting and pole-mounted fixed installation.
