Or change the voltage from low to high. In power plants, voltage transformation transmission is generally used to convert the generated electric energy into high voltage for transmission, with less loss.
Power distribution cabinet: according to the load requirements, sort out the electricity consumption, and carry out three-phase four-wire power distribution in the power distribution cabinet to meet the equipment use requirements.
Some electricity needs 380V, some need 220V, some equipment needs to be started directly, some need frequency converter or soft starter, autotransformer step-down starter, etc., all of which need to be distributed in the power distribution cabinet.
