, busbar is aluminum with aluminum - Aluminum bus bar expansion joint, is copper busbar copper - Aluminum bus bar expansion joint
Aluminum and copper should not be directly overlap, there is no parts are barely made hot tin must be part of copper busbar joint processing, namely in the copper aluminum layer is not easy to be between two kinds of metal corrosion of metal "tin", to prevent the electrochemical process of the copper and aluminumHenan Chalco slip joint purpose: widely used in all kinds of generator, transformer, switch, bus, large current in the electrical equipment, such as electrolysis, smelting flexible electrical connection.
