AC Distribution Panel

An AC distribution panel is a specialized integrated power distribution system designed for AC power systems, integrating low-voltage circuit breakers, isolation switches, load switches, current and voltage transformers, watt-hour meters, protection devices, and busbars into one or more enclosed metal cabinets based on user-specific electrical single-line diagrams. Its core mission is to safely, efficiently, and reliably distribute AC power from transformers or municipal grids to downstream circuits and loads, quickly isolating faults during overload, short circuit, or leakage. A standard panel features an incoming unit (main circuit breaker or isolation switch for power access and cutoff), a metering unit (current and voltage transformers and watt-hour meters for energy measurement), a feeder unit (multiple outgoing circuit breakers for lighting, power, and air conditioning loads), a busbar system (copper or aluminum bars for internal power transmission), a control and protection unit (relays, PLC controllers for automatic switching and motor protection), and an optional reactive power compensation unit (capacitor banks for power factor improvement). Cabinet design prioritizes heat dissipation, IP rating, insulation distance, and operational and maintenance convenience.

We build AC distribution panels on an OEM basis from the buyer's single-line diagram and run them on a standardized batch production line for repeat commercial projects. This means the incoming, metering, feeder, and optional compensation sections are laid out exactly to the contractor's drawing, while batch tooling keeps enclosure folding, busbar bending, and wiring labor consistent across a shopping mall, office tower, or chain retail build-out.
