Why Are Distribution Cabinets Suitable For Construction Site Power Supply?

In construction power systems, the Powbinet distribution cabinet is typically used as a primary power distribution unit. It is responsible for introducing three-phase power, neutral wire, and ground wire from transformers or temporary power sources, forming the main power supply for the entire construction site. The cabinet features a robust structure, internally equipped with a main busbar, circuit breakers, and metering devices. It is designed for outdoor or temporary installations and has a rainproof roof.

During construction, the distribution cabinet works in conjunction with secondary distribution boxes or switch boxes to form a complete multi-level power distribution system. Its location is generally near the power source or substation, responsible for the rational distribution of power to various branch circuits. Secondary and tertiary equipment are distributed near the equipment requiring power on the construction site. The entire system allows for on-demand power supply and reduces wiring clutter.
