The conductor of the power cord is its most important component. Without the conductor, the entire power cord of Rolex GMT-Master II replica will not be conductive and can only be discarded. The importance of the conductor is unquestionable, so be careful in the choice of wire. Most of today's power cord manufacturers use copper wires to make conductors. So why is it made of copper wire?

　　 One, conductivity

　　Good conductivity is an important reason why copper wire is selected as the core component of the power cord. Regardless of any metal wire as a conductor, there is resistance. Resistance will affect the flow of current, so when choosing a metal wire with a slightly smaller resistance, copper wire is one of them.

　　 Two, bending resistance

　　 Copper wire has undergone various tests and found that its bending resistance is better. The most commonly used is to fix one end of the single wire, add weight to the other end to make it sag, and then bend it back 180 degrees until the copper wire is broken. The more times the wire is bent, the bending resistance is indicated. The higher the fold performance.

　　 3. Tensile strength

　　Because the power cords are used in different environments, some have to be carried out in high mountain areas, and some have to cross rivers. Different environments have extremely high requirements for the tensile strength of conductors. The tensile strength of copper wire is very high, so it can be used in mountainous areas and river-rich areas. Generally, copper wires are classified into hard copper wires, semi-hard copper wires, and soft copper wires according to their tensile strength, which conform to the selection of tensile strength in various industries.

　　The performance of the above three points is that copper wire is better than other metal wires. Therefore, manufacturers of power cords generally use copper wires for conductor production. Unless the customer has other requirements for the conductor, the manufacturer will use other metal wires for production. best rc airplanes
