Expand the full text Fig. 4 Cross branch connection of single-strand copper conductor As shown in Fig. 5,titanium tubing price, 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 enda)]. One group is inserted into the trunk core wires,ti6al4v, 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. 8ize, which will cause line failure over time, so the aluminum conductor is usually connected by pressing. 2. Pressing connection Pressing connection means that a copper or aluminum sleeve is sleeved on the connected core wire, Titanium 6Al4V wire ,titanium plate gr7,  special step-down transformer (1 kVA, primary 220V, secondary 6 ~ 12V) with special welding tongs and carbon rod electrodes, 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,ti6al4v eli, 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.
