A screw crimping method for single strand Aluminum Conductor:
1. Screw crimping connection is suitable for single strand core wire connection with small load. On the circuit, it can be connected by the connection post screw on the switch and the lamp head box porcelain connector. Before connection, the aluminum oxide film on the surface of the core wire must be removed with a wire brush, and vaseline zinc paste powder or neutral Vaseline shall be applied immediately, and then screw crimping can be carried out. When making a straight-line connection, first roll up 2 wire ends of each aluminum conductor near the end of the wire and connect them to a connecting post, then screw several wire ends together and then crimp them.
Straight line connection of multi-core Conductor:
1) First, disperse and straighten the core wires stripped of the insulation layer, then tighten the core wires close to 1 / 3 section of the insulation layer, and then disperse the remaining 2 / 3 core wires into umbrellas as as shown in the figure, and straighten each core wire.
2) The two corymbose wires must be inserted to the end of each other.
3) After pinching all cores on both sides of the fork, straighten each core wire and make the spacing of each core wire uniform; at the same time, use wire pliers to tighten the fork to eliminate the gap.
4) First, at one end, fold up the adjacent two core wires at the diameter width of about three single core wires from the center line of the fork, and form 90 °
5) Then tightly wrap the two strands of core wires in clockwise direction for two turns, and then fold them back to 90 ° and lie on the axis position before folding.
6) Then, the 2 cores adjacent to the front of lying flat are folded into 90 °.
7£© When winding the remaining 3 core wires to the second circle, cut off the first 4 core wires at the root respectively and clamp them flat; then wrap 3 core wires for 3 circles, and then cut off the remaining ends. Clamp the cut without burr
