Description

technical field [0001] The invention relates to the field of distribution box materials, in particular to a distribution box shell material and a preparation method thereof. Background technique [0002] The distribution box is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then the low-voltage side of the transformer is stepped down to lead to low-voltage The distribution box and the low-voltage distribution box are connected to each power distribution panel, control box, and switch box. Inside, some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices are assembled into one The equipment of the power distribution device that meets the design function requirements. The high and low voltage distribution box is also called: high and low voltage switchgear or high ...
