PGS-12kV Pole-Mounted Load Switch – Maintenance-Free, Factory Direct
1. Product Overview 产品概述
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. It supports manual operation (insulated operating rod) and electric remote operation (optional), which can meet the operation requirements of conventional distribution networks and intelligent distribution networks. The insulation system adopts high-quality hydrophobic silicone rubber, with a large creepage distance, which can effectively prevent pollution flashover accidents and ensure the safe and stable operation of the equipment in outdoor environments for a long time.
