Structure Introduction

The switch equipment is designed according to GB3906-91 metal armoring seal switch equipmnent. The rectifier body is made up of the cabinet body and draw-out parts (namely handcart placed in the middle. See charter 1. The cabinet divides into four separate rooms, the outer covering protection grade is IP4X,when each small room and the circuit breaker is opened, the protection grade is IP2X. It can suspend the inlet, outlet line. cable's inlet, outlet line and other function plan. After arranged and combined, it can beome each kind of plan form of the power distribution equipment. This switch equipment may be installed and maintained from the frontage，therefore it may compose the dul arrangement back to back and be installed against the wall, improving the switch equipment' s security and flexibility and making full use of the occupying area.
