The internal bracket is used to place various components.

[0003] When the electrical panel cabinet is working, due to the large number of components installed inside and the large voltage passing through, the components generate a lot of heat. The existing electrical panel cabinet lacks a heat dissipation structure, which can easily cause the heat generated by the components to not be dissipated in time, thus affecting the service life of the components. At the same time, the wires led out of the components will also generate heat, and the wires will be squeezed together through the wiring structure, which can easily cause internal damage due to the inability to dissipate the heat. For this reason, we propose an electrical panel cabinet and wiring structure. Utility Model Content
