Cabinet Structure
The basic structure of the switchgear cabinet is assembled from C-shaped profiles. The C-shaped profiles are made of steel plates bent with a modulus of E=25mm for mounting holes. All the cabinet frames and inner partitions are galvanized for purification. The surrounding door panels and side panels are coated with high-voltage electrostatic spray. The basic structure of the cabinet is shown in Figure 1, and the basic dimensions of the cabinet are shown in Tables 1 and 2.
