Product Overview

The QCX F-24 series SF6 gas-insulated metal-enclosed switchgear (C-GIS) is a switch main unit used in distribution networks and is now widely used in State Grid, Southern Grid, high-speed railways, subways, large cities, mines, new energy, and other locations.
All live parts and switches are enclosed within the same stainless steel welded SF6 insulated sealed gas chamber. The entire switchgear is unaffected by external environmental conditions, ensuring operational reliability and personal safety.
The switch units are designed modularly and can be freely combined according to customer requirements.

Product Features

Multi-scheme

There are multiple switch schemes in the design, including integrated and split types, which can be selected according to project requirements.

Maintenance Free

The high-voltage conductor is completely sealed, with incoming and outgoing lines through insulating bushings, maintenance-free for the life cycle.

Miniaturization

Compact structure, reducing the footprint by about half compared to traditional switchgear.

Wide Application

It can be used in high-altitude and humid coastal areas.
