The main difference: GGD parameters are fixed switchgear, GCK, GCS, MNS is a chest of drawers. GCK and GCS, MNS cabinet drawers of different propulsion mechanism; GCS and MNS cabinet main difference is that the cabinet can only do single operation GCS switchgear cabinet sales, cabinet depth 800mm, MNS cabinet can do double-sided operation cabinet, cabinet depth 1000mm.
