Diagram of complex copper wire connection

1.Connection of wires in the same direction. For single strand conductor, the core wire of one wire can be tightly wound around the core wire of other wires, and then refold and compress the core wire ends of other wires. For multiple strand wires, cross the cores of the two wires with each other, and then twist and tighten. For the connection of single strand wire and multiple strand wires, the core wire of multiple strand wires should be tightly wound on the core wire of single strand wire, and then fold back and compress the end of single strand core wire. 

2.Connection of double core or multiple-core wires and cables. When connecting double core sheathed wire, three core sheathed wire or cable or multiple-core cable, we should stagger the connection points of each core wire as far as possible, so as to prevent leakage or short circuit between wires.

Tips: aluminum conductor and copper wire can be stranded connection, but in contrast, the surface of aluminum core wire is easy to oxidize, and it is easy to cause circuit failure after using a long time. Therefore, aluminum wire is usually connected by tight compression method.
