Illustration of Common Conductor, Wire Connection Method and Electrical Wire Connection Method

Original Title: Illustration of Common Wires,  4 Cross branch connection of single-strand copper conductor As shown in Fig. 5,6al4v titanium bar, tightly wind the wire ends of the upper and lower branch core wires on the trunk core wire for 5 to 8 circles, and then cut off the redundant wire ends. The wire ends of the upper and lower branch core wires may be wound in one direction [see fig. 5 (a)] or in both left and right directions [see fig. 5 (B)]. Fig. 5 (3) Direct connection of stranded copper conductors.  6 (4) Branch connection of multi-strand copper conductor. There are two methods for T-shaped branch connection of multi-strand copper conductor. One method is as shown in Figure 7. The branch core wire is bent by 90 ° and then parallel to the trunk core wire [see Figure 7 (a)], and then the wire end is folded back and tightly wound on the core wire [see Figure 7 (B)]. Fig. 7 Another method is as shown in Fig. 8. Twist and tighten about 1/8 core wires of the branch core wires close to the insulation layer, and divide the remaining 7/8 core wires into two groups [see Fig. 8 (a)]. One group is inserted into the trunk core wires,titanium round bar, and the other group is placed in front of the trunk core wires, and wound 4 to 5 turns to the right in the direction shown in Fig. 8 (B).  One end of the copper-aluminum connecting sleeve is made of copper, and the other end is made of aluminum, as shown in Figure 15 (a). When in use, insert the core wire of the copper wire into the copper end of the sleeve, insert the core wire of the aluminum wire into the aluminum end of the sleeve, and then press the sleeve tightly, as shown in Figure 15 (B). Fig. 15 Another method is to connect the copper conductor with aluminum sleeve after tin plating. Because of the small difference between the standard electrode potentials of tin and aluminum, a layer of tin sandwiched between copper and aluminum can also prevent galvanic corrosion.
The specific method is to plate  as shown in Figure 19. Fig. 18 Gas welding refers to the use of the high-temperature flame of the gas welding gun to heat the connection points of the aluminum core wires,titanium exhaust tubing, so that the aluminum core wires to be connected are melted and connected with each other. Before gas welding, the aluminum core wires to be connected shall be stranded or bound with aluminum wires or iron wires, as shown in Fig. 19.
