How do you connect the aluminum wire with the copper wire?
In accordance with the safety operation code, aluminum wire can not be connected with copper wireSolution (due to live lines, operation is extra careful)1 riveted aluminum wire and copper wire riveted together2 using the soldering method of aluminum and copper welding together.3, the best thing is to change the wire to copper wire
This is the most critical, is very easy to wire in the air oxidation, forming a layer of oxide on the surface, coupled with aluminum copper than the hardness of small, it will greatly increase the contact resistance of aluminum and copper connections, when the current through this connection, the contact resistance will be fever, if it is a large current then, the heating will be very serious, will connect at burned.
The resistivity of aluminium wire and copper wire is different
