Description

Product Encyclopedia
The GW4 Outdoor High Voltage Isolating Switch Vacuum LBS Load Break Switch is designed to deliver reliable, safe, and efficient switching for outdoor High Voltage networks. Combining vacuum interruption technology, load break capabilities, and robust insulation, it ensures operational continuity and low maintenance for substations, industrial networks, and utility systems.

This guide provides insights into storage conditions, customer feedback, upgrade maintenance plans, and practical solutions, making it a valuable resource for engineers, operators, and procurement specialists.

Overview

The isolating switch is of a unipolar type, and the three poles can be connected by a connecting rod into a three-pole type that can be linked. It is equipped with CS11 or CS8-6D manual mechanism. CS17 is used for the isolating switch with double grounding device. (The electric mechanism can be equipped as needed).

The isolation switch has reasonable structure and flexible operation: it can be used for single pole or three poles, and the installation is convenient: the touch knife is opened, and the insulation is safe and reliable. It can also be grounded or double grounded according to user needs.
