Commonly used cantilever control box is made of wood and metal, because the metal cantilever control box protection level is higher, so it is still more used for metal, metal is also divided into iron, carbon steel, stainless steel, aluminum, etc.

The cantilever control box can be divided into:

1, fixed panel type cantilever control box, often called switch board or distribution screen. It is a kind of open-type cantilever control box with a panel block, the front has a protective effect, the back and side can still touch the live part, the protection level is low, can only be used for the continuity of power supply and reliability requirements of low industrial and mining enterprises, as a centralized power supply substation.

2. Protective (i.e. enclosed) cantilever control box refers to a low-voltage cantilever control box with all sides closed except the mounting surface. The electrical components of the cabinet, such as switches, protection and monitoring controls, are installed in a closed enclosure made of steel or insulating material, and are mounted reliably against or off the wall. Cabinet between each circuit can not add isolation measures, can also be used to ground the metal plate or insulation plate for isolation. Usually the door is mechanically interlocked with the main switch operation. In addition, there is a protective console cantilever control box (console), the panel is equipped with control, measurement, signal and other electrical appliances. The protective cantilever control box is mainly used as the power distribution device in the process field.

3. Drawer-type cantilever control box. This kind of cantilever control box USES the steel plate to make the closed shell, the electrical components of the incoming and outgoing circuit are installed in the drawer that can be drawn out, constitute the functional unit that can complete a certain kind of power supply task. The function unit and the bus or cable are separated by the grounded metal plate or the function plate made of plastic to form the three areas of bus, function unit and cable. There is also isolation between each functional unit. Drawer type cantilever control box has higher reliability, security and interchangeability, is a more advanced cantilever control box, the cantilever control box most refers to the drawer type cantilever control box. They are suitable for industrial and mining enterprises and high-rise buildings which require high reliability of power supply.

4, power, lighting distribution cantilever control box. For enclosed vertical installation. Due to the use of different occasions, the shell protection level is also different. They are mainly used as power distribution devices in the production site of industrial and mining enterprises.

Above is the cantilever control box of several categories, for you to learn reference!
