In the decoration of the house, we will face such a problem ---how to join electrical wires？This is an easy thing for a professional electrician, but it is difficult for people who have no experience in this field.
How to join electrical wires？Straight line connection of single-strand copper wire and connection of T - shaped branch.
(1)Straight line connection of single-strand copper wire
First,the two thread are whittled a length of wire core,the oxide layer on the surface of the wire core is cleared, the two wire core is crossed into a X shape, and each other is twisted around 2 to 3 circles, and then a straight line is pulled.Please pull the two straight thread close around 6 laps on each side.Then remove the remaining threads and clamp the end of the line.
(2)connection of T - shaped branch.
Please split the sharpener line core with trunk line.leave the root of the branch line core about 3 ~ 5mm, and then clockwise in the trunk line on the core of 6 to 8 laps, with wire pliers cut off the wire core, the end of the clamp flat wire.
How to join electrical wires？Connection method of conducting wire.
The aluminum core wire should be connected with the screw bolt and press the connecting pipe.This method is suitable for the connection of aluminum core wire with small load.According to the specification of aluminum wire, select the appropriate aluminum pressure pipe. First, clean up the crimping department, two aluminum core wire relative penetration pressure to take over, the two line end extends out of the pressure over about 30 mm, and then use the crimping pliers crimping. The first pressure hole should be pressed at one side of the aluminum core end. The quality of compression?should meet the technical requirements.
