Product Features:
❖ The switchgear frame is a modular structure, with the basic skeleton assembled from C-shaped steel. All structural components of the cabinet frame are galvanized for enhanced durability.
❖ Each cabinet in the modular low-voltage switchgear is divided into three sections: the horizontal busbar compartment (at the rear of the cabinet), the drawer compartment (at the front of the cabinet), and the cable compartment (at the bottom or front right side of the cabinet). The sections are separated by steel plates or high-strength flame-retardant plastic functional panels. A metal plate with ventilation holes separates the upper and lower drawers, effectively preventing accidents caused by arcing from switchgear failure or short circuits between busbars and other circuits.
❖ The structural design meets various incoming and outgoing cable configuration requirements: top input and output, top input and bottom output, bottom input and top output, bottom input and output.
❖ The components have high versatility and flexible assembly. With a module of E=25mm, the structure and withdrawable units can be combined freely to meet system design needs.
