Product Overview

The QCX E environmentally friendly gas-insulated metal-enclosed switchgear (C-GIS) is an environmentally friendly C-GIS product independently developed by Beijing Qingchang. The design adheres to environmentally friendly and green concepts, using dry air as the insulating gas. The voltage rating covers 10-35 kV, with currents ranging from 630 to 3150 A, and a rated breaking current of 25–40 kA. The equipment offers extremely high safety and reliability, ensuring the continuous and stable operation of power systems and the personal safety of operators. It also features a user-friendly interface, making it easy for on-site operators to use.
The QCX E-series switchgear adopts modern and innovative switchgear design concepts, with multiple functional modules available for selection. Commonly used functional modules include V, V-PT, V-G bus tie, and M metering, among others. Other modules can be customised according to the requirements of the primary system diagram when needed. These functional modules can be installed on-site.
