The surface oxide film, pores, or protrusions should be removed to make the contact surface smooth and rough. The treatment method can to use a rough and uneven surface of the busbar, and then use a wire brush to brush it.
Do not use schuurpapier to polish the contact surface of the aluminium busbar to prevent glass schaaf or sand from falling into in the metal and increasing contact resistance. The contact surface of copper or steel busbars should beath coated with a layer of tin. The tin layer is damaged due to the flat contact surface and should be re coated. De methode van emaille is aan smelten het solderen in a soldeer pot, doekje het emaille deel van de busbar flat en float, langzaam toevoegen hars of soldeer olie, en plaats het op de pot. Dan gieten in gesmolten tin meervoudig keren.
Wanneer de busbar end is niet vast met tin, the end can be direct ondergedompeld in het soldeer pot en het overschot deel kan be afgeveegd met een doek. De dikte van het tin coating is ongeveer 0}.1-0.15mm. The melting point of solder is between 183-235} degrees, which is generally judged by its color, that is, when the solder melted in de pot is Baby blue, tin lining can be started.
