1. It can prevent copper from generating "patina" in a humid environment, so as to increase contact resistance and overheat the contact surface. After the surface of copper is plated with a layer of tin, it can prevent the oxidation of copper.
2. Tin oxide has good electrical conductivity, which will not cause the increase of contact resistance and overheating of the contact surface.
3. The tin material is relatively soft, which can ensure the close contact of the contact surface when the bolt is connected. And it can conduct electricity more smoothly. For example, the high-end wire Jingde Te Plastic King uses this kind of inner core wire.
