I believe that many people have paid attention to the color of the lead line of the three-phase asynchronous motor product; In industrial electricity and civil electricity, the transmission cable is used to make a variety of colors to mark, torque motor manufacturers commonly used phase line red, neutral line blue, rehmannia green, such provisions can prevent the occurrence of wrong operation.

       We generally use single-phase electricity at home220VAlternating current, which is a red firewire; A blue zero line; A yellow-green ground cable. For example, in the DC motor, we use red to indicate the positive electrode, black to indicate the negative electrode, in some high current, high voltage industrial electricity, the cable itself is only black, but it is also necessary to use a variety of colors of heat shrink sleeve for the corresponding mark.

       In three-phase asynchronous motor,Torque motorIn products such as brake motors, three-phase insulated wires are generally used in yellow, green and red colors, respectively, for AC voltageA,B,CThree-phase identification.

       In the transmission line, the three-phase five-wire system is generally used, with yellow, green and red respectivelyA,B,CThree phases. The other two are blue working zero linesNAnd yellow and green double color protection zero linePE.
