The use and operation environment of solar inverter is generally harsh, and it is often installed in desert, barren mountain, water surface, roof and other environments. It requires that the resistivity of the photovoltaic cable must be good, not easy to oxidize, and can be used for a long time. Therefore, the soft connection of tinned copper conductive tape is the conductor that best fits the use environment and has the most stable electrical performance.
The appearance of the tinned copper braided tape soft connection is silver because tin is a silver metal. The process of tinned copper conductive tape is more complex than bare copper wire. It involves pulling pure copper rods into wires and then using a hot tin plating process to coat the surface of the copper wire with a thin layer of tin. Tin is very stable in air at room temperature because a dense oxide film is formed on the surface of tin, preventing its further oxidation. Therefore, tin plating on the copper surface does not affect the resistance and can improve the oxidation resistance of copper to a certain extent.
