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.
Product Features
Flexible Combination
