[0002] As the name suggests, high and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high-voltage switchgear, which is then stepped down by the transformer and led to the low-voltage side to the low-voltage distribution cabinet. The low-voltage distribution cabinet is then led to the distribution boards, control boxes, and switch boxes of various power users. The equipment in the cabinet is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.
