Fixed panel power distribution cabinet protection level is low, can only be used for some of the security requirements are not high and continuous power supply occasions, such as industrial and mining enterprises for the power supply room centralized power supply.
2, protective power distribution cabinet protective power distribution cabinet and the fixed panel is the distribution cabinet compared to a real sense of the cabinet, in addition to the installation side of all sides have baffle seal. The cabinet of the protective power distribution cabinet is made of insulating material. The internal electrical components are isolated from the outside. The protection between the components can also be shielded. Therefore, the safety grade of the protective distribution cabinet is high and can be applied to the power distribution Device.
3, drawer-type distribution cabinet drawer-type distribution cabinet is one of the most secure distribution equipment, it is made of steel plate cabinet, cabinet installed in the drawer, the electrical components are installed in the drawer, constitute an independent Functional unit. Drawer type distribution cabinet reliability, interchangeability and safety are higher than the above two power distribution cabinet, can be applied to the power supply reliability of the high concentration of centralized control distribution center.
4, power lighting distribution cabinet power lighting distribution cabinet with a closed installation, the safety level according to the different requirements of the use of different occasions. Power lighting distribution cabinet as a low-level power distribution equipment, such as for industrial and mining production site of the distribution control.
