Structure introduction:The switchgear is designed according to the armored metal-enclosed switchgear in GB3906--2006. The whole is composed of two parts: a cabinet and a middle-mounted withdrawable part (ie, a handcart). The cabinet is divided into four separate compartments, the enclosure protection level is IP4X, and the protection level of each compartment and circuit breaker room is IP2X when the door is opened. With overhead incoming and outgoing lines, cable incoming and outgoing lines and other functional schemes, arranged. After being combined, it can become a power distribution device of various schemes. A.Busbar room B. Circuit breaker handcart room
