What are the Different Types of Crimping Tools?

Crimping pliers are necessary tools for power line crimping in the construction and maintenance of lines.

Crimping pliers

Crimping pliers

By fuel tank, power mechanism,

Split crimping pliers need to be equipped with corresponding

Rechargeable crimping pliers are compact in structure and light in weight, and the arrangement of the forward and backward operation buttons is reasonable. Can be operated with one hand;

Adopting high and low two-stage plunger pump drive design, fast and labor-saving operation;

1. Linear connection method for multiple (single) stranded aluminum wires

(1) Select the pressed film and oval aluminum sleeve according to the cross-section of the conductor; (2) Strip the insulation sheath of the conductor at the joint. The stripping length should be the length of the aluminum sleeve usually plus 5-10mm (This item), use a wire brush to remove the oxide layer (film) on the surface of the core wire; (3) use another cleaned wire brush to dip some Vaseline zinc powder paste to evenly modify the core wire to prevent the oxide layer from regenerating. (4) Use a round bar wire brush to remove the oxide layer and greasy dirt on the inner wall of the aluminum casing. It is best to apply Vaseline zinc powder paste on the inner wall of the tube. (5) Pierce the two core wires into the aluminum sleeve oppositely, so that the two wire ends meet at the center of the aluminum sleeve. (6) Select the appropriate wire mold according to the thickness of the aluminum sleeve and install it on the crimping pliers. After tightening the set screw, insert the core wire with the aluminum sleeve into the wire mold. (7) Align the aluminum sleeve and pinch the pliers handle firmly for crimping: first press the two pits at the two ends, and then press the two pits at the center. After the joint is crimped, you should check that the bend of the aluminum sleeve should not be greater than 2% of the length of the tube, otherwise straighten with a wooden hammer; the aluminum sleeve should not be cracked; Or "cramps" inhomogeneous appearance. (8) Wipe off the remaining grease and apply a layer of quick-drying asphalt paint to both ends of the aluminum casing and the joints. Then, the aluminum sleeve and exposed wires are covered with two layers of yellow wax tape, and then two layers of black tape.

2. The connection method of the aluminum core multi (single) stranded wire and the equipment of the bolt crimping type terminal

(1) Select a suitable aluminum lug according to the thickness of the core wire. (2) Brush off the oxide layer on the core wire and evenly apply Vaseline zinc powder paste. (3) Brush the oxide layer on the inner wall of the terminal ear jack, and it is best to apply Vaseline zinc powder paste on the inner wall. (4) Insert the core wire into the insertion hole of the terminal ear, and insert it to the bottom of the hole. (5) Select the appropriate wire mold, press two pits on the front of the lug, first press the outer pit, and then the inner pit. The two pits must be on the same line. (6) Wrap an insulation tape between the root of the wiring ear and the insulation stripped off of the wire (the insulation tape should be wrapped from the wire insulation). (7) Brush off the oxide layer on the reverse side of the lug and apply Vaseline zinc powder evenly. (8) Put the opposite side of the terminal ear on the screw of the terminal of the terminal, and then put the flat washer and the spring washer in order, and fix it tightly with a nut.
