How do aluminum and copper wires join together?
Views:  Addtime:2023-06-20

Aluminum wire and copper wire connection skills:

1, a single small section of copper, aluminum wire connection, copper wire should be tin and then connected with aluminum wire.
2. When multi-strand large-section copper and aluminum wires are connected, copper-aluminum transition connection tubes or copper-aluminum transition wire clips should be used.
3. If the aluminum wire is connected to the copper terminal of the switch, the copper and aluminum transition nose should be used.
4, one is a copper joint, one is an aluminum tube, in the past are copper and aluminum extrusion butt welding machine fusion welding, now there are advanced copper and aluminum flash butt welding machine fusion welding. There are other techniques, of course.

Connection note:
1, copper wire and aluminum wire connection, the connection will appear electrical corrosion, generally aluminum wire is corroded first leading to phase failure damage electrical equipment. It's the electrochemical reaction of two different materials that causes corrosion.
2, if there is no copper aluminum joint, you can use copper wire with copper joints, aluminum wire with aluminum joints, but do not directly connect, must be filled in the middle of a layer of zinc as a transition layer, because copper zinc does not produce electrical corrosion, aluminum zinc does not produce electrical corrosion, so as to solve the problem of copper aluminum electrical corrosion.
