A low noise switchgear board is provided to improve a heat radiating effect by dually molding a noise reducing panel with aluminum having a high thermal conductivity. A low noise switchgear board(100) includes a frame(120), a noise reducing unit, a noise reducing surface, and at least one noise reducing panels(130). The frame forms a body of the switchgear board. The noise reducing unit reduces a noise generated in an internal apparatus of the switchgear board while closing an inner part of the body. The noise reducing unit is mounted on the frame. The noise reducing surface extinguishes a noise passing the noise reducing unit. The noise reducing panels equipped with a connection groove and a connection protrusion are connected to one portion and the other portion of a panel body. |
