Product Description

 

The switchgear is designed according to the armored metal enclosed switchgear in GB3906-91. The whole is composed of two main parts: a cabinet and a central withdrawable component (i.e. a handcart) (see figure). The cabinet is divided into four separate compartments, with an enclosure protection level of IP4X. When the doors of each compartment and circuit breaker room are opened, the protection level is IP2X. A complete distribution system device is formed by arranging and combining overhead incoming and outgoing lines, cable incoming and outgoing lines, and other functional schemes. This switchgear can be installed, debugged, and maintained from the front, so it can be back-to-back, arranged in a double arrangement, and installed against the wall, improving the safety, flexibility, and reducing the footprint of the switchgear.
