The main role of tinned copper wire is to prevent the bare copper from being oxidized in the air, producing patina, which affects the electrical conductivity of the cable. Most occasions can use tinned copper wire and bare copper wire, but sometimes we have to use tinned copper wire.

1. Mobile cables include drag chain cables, robot cables, spreader cables, reel cables, etc. When the cable is bundled, the copper wire inevitably comes into contact with the air. Because bare copper is easy to oxidize, once the oxidized copper wire will be more brittle, the machine will easily break the core when it moves. Therefore, it is best to use tinned copper wire for mobile cables.

2. Rubber cables, especially vulcanized rubber cables. Because bare copper will react with sulfur to form copper sulfide, the copper wire will be oxidized during this time.

3. Cables that require higher welding speeds. Because bare copper will be oxidized if exposed to the air for a long time, and an oxide film will be formed on the surface. At this time, soldering is more difficult, and tinned copper wire will not have this problem.

Tinned copper wires are more expensive than bare copper. Some cable manufacturers use bare copper instead of tinned copper wires in order to save costs. They do not know that pure copper cables cannot be used in some situations. Kuka cable consistently uses tinned copper cables and is committed to producing reliable, high-quality cables.
