First of all, we should understand that the installation method of copper bar in the cabinet is divided into two forms, horizontal and vertical, and the current carrying capacity of vertical is slightly larger than that of horizontal, so the main bus bar of power distribution cabinet is mostly vertical. There are copper bars, and the current carrying capacity of copper wires will also change with the ambient temperature. Here we use an ambient temperature of 35 degrees Celsius. Under different ambient temperatures, the ampacity obtained by looking up the table needs to be multiplied by the correction coefficient under different ambient temperatures to obtain the ampacity under different ambient temperatures. The higher the temperature, the lower the ampacity.
The above is about how to choose the copper bar, I hope it can be helpful to everyone. Because copper has better conductivity than aluminum, copper bar has been widely used in electrical equipment, especially in complete sets of power distribution equipment. Generally, copper bars are used for phase A, B, C, N bus bars and PE bus bars in power distribution cabinets. Copper bars are generally marked with phase color letters or coated with phase color paint during use. Phase A copper bars are marked with yellow, Phase B is green, Phase C is red, and Phase N is light blue, PE bus is yellow-green double color.
