GCS low-voltage draw-out switchgear adopts standardized modulus design, the main frame adopts 8MF cold-formed profile, and the main frame are mounted with module holes E=20mm. The structure is assembled and partially welded. Each functional unit can operate relatively independently, and the outgoing line function unit can install up to 22 outgoing line circuits. The propulsion mechanism adopts a screw propulsion mechanism, which is stable and reliable. The upper and lower in (out) lines and other options can be used for users. It is suitable for power plants, petroleum, petrochemical, metallurgy, textile, high-rise buildings and other low-voltage distribution systems.
