Moreover, due to actual needs, the application environment and conditions of various equipment are more complicated, especially the transportation of power resources has been difficult to solve completely. At present, the long-distance transportation of electric energy is generally achieved by configuring power distribution cabinets. The power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is the general name of the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads to provide protection, monitoring and control for the loads.

At present, power distribution cabinets can be divided into two categories: indoor type and outdoor type. Outdoor type power distribution cabinets must face a more complex natural environment because they are exposed, which puts higher demands on their own hardware conditions.
