Distribution cabinet classification

(1) The primary distribution equipment is collectively referred to as the power distribution center. They are centrally installed in the substations of enterprises, distributing electrical energy to lower level distribution equipment in different locations. This level of equipment is close to the step-down transformer, so the electrical parameter requirements are high and the output circuit capacity is also large.

(2) Secondary distribution equipment is a collective term for power distribution cabinets and motor control centers. The power distribution cabinet is used in situations where the load is relatively dispersed and there are fewer circuits; The motor control center is used in situations with concentrated loads and multiple circuits. They distribute the electrical energy of a certain circuit of the upper level distribution equipment to the nearby load. This level of equipment should provide protection, monitoring, and control for the load.

(3) The final level distribution equipment is collectively referred to as the lighting power distribution box. They are located far from the power supply center and are scattered small capacity distribution equipment
