Factory power distribution project

High and low voltage power distribution projects include 10/0.4kV high and low voltage power distribution projects and 0.4kV low voltage power distribution projects. The high and low voltage power distribution project refers to the project that is introduced from the 10kV power supply side of the Southern Power Network to the user side and converted into a 0.4kV power supply through transformer transformation. It is the core part of an enterprise; a 0.4kV low voltage power distribution project refers to the project from the enterprise—the whole system engineering from the power room to the power center.

Safety distance of power distribution station and power distribution device

1. Minimum electrical safety clearance (mm) for indoor and outdoor power distribution devices

Remarks: 1. When the fixed switch cabinet is arranged against the wall, the precise distance between the back of the cabinet and the wall should be greater than 50mm, and the precise distance between the side and the wall should be greater than 200mm;

2. Width of the passage When a wall of the building encounters the partial protrusion of the column, the width of the passage of the protruding part can be reduced by 200mm. A set of equipment
