The whole is composed of a cabinet body and a built-in withdrawable part (i.e. truck) two parts. Cabinet body is divided into four separate compartments, shell protection grade IP4X. Each compartment and the circuit breaker room door open door grade IP2X. With the aerial import and export line, cable and other functions of the cable, after the arrangement, can become a variety of power distribution plan Device. From the front to the installation, debugging and maintenance of the switching devices, so it can be formed back to back double array and installed on the wall, to improve the safety and flexibility of the switchgear, the occupation area is reduced. 2.1 shell and other Switch equipment shell is imported aluminum zinc coated steel sheet, by CNC |
