Structuralfeatures

The switchgear is designed according to the armored metal enclosed switchgear in GB3906-2012, IEC62271-200:2012. The whole thing is composed of two parts: the cabinet and the central pull-out part (i.e. handcart) (see Figure 1). The cabinet is divided into four separate compartments. The protection level of the shell is IP4X. When the door of each small compartment and the circuit breaker room is opened, the level is IP2X. It has overhead incoming and outgoing lines, cable incoming and outgoing lines and other functional solutions. After arrangement and combination, it forms a complete power distribution system device. This switchgear can be installed, debugged and maintained from the front, so it can be back-to-back, double arranged and installed against the wall, which improves the safety and flexibility of the switchgear and reduces the floor space.
