What kind of copper is used for the power cord?
At present, the power lines on the market mainly use copper wires, and copper wires are widely used because of their good electrical conductivity. However, not all types of copper wires can be used in the production of power lines, and their application ranges are also different according to their different properties. So, what kinds of copper wires can be used in the production of power cords?
Tinned Copper Wire
As the name suggests, it is coated with a layer of tin on the outside of the copper wire, which can enhance the solderability of the copper wire, protect the copper wire from corrosion during the extrusion process of PVC material or rubber insulation, and prevent the PVC sheath and rubber insulation from aging, which is effective Extend the service life of the power cord.
Oxygen-free copper wire
Oxygen-free copper is a copper wire with very little oxygen. Therefore, oxygen-free copper wires are not easy to oxidize and become brittle, and can be used to make various vacuum tubes and semiconductor wires. Oxygen-free copper contains less oxygen and is not easily oxidized compared with ordinary copper wires, thereby prolonging the blackening time of the copper wires and prolonging the use time of the power cord.
Soft copper wire
It is a copper wire product that is produced through a cooling process step after heating. It has good flexibility and flexibility.
