According to the relevant standards, the error of the length of the wire cannot exceed 2%, and the diameter of the section wire cannot exceed 0.02%.
It is easy to distinguish from the conductor material. The conductor core of the national standard power cord is basically made of oxygen-free copper. The power cord made of oxygen-free copper has low resistance, stable transmission, anti-oxidation and lo
The insulation layer of fake and inferior wires looks very thick, but in fact, most of them are made of recycled plastic. As long as you squeeze a little harder, the squeeze will turn white and powder will fall off. All wires should be passed through PVC
