Construction site plumber threading, when will the hydropower threading be carried out

It is a small "rigid wire". The wire is too soft,,, head is bent by hand "pliers", bent a little more, "I don't know what to type for you, you can't tell me?? People turn high hydropower", skills,,, if you can't wear it, turn the wire a few times, turn the hand with a little force to wear, "the wire is small but if you want it to turn, yes, hold the main wire about 15-20cm with both hands, if you can't turn it,, bolt I didn't say", wire and wire joint, steel wire head bend 360 degrees, use pliers to pliers, don't be too big, first tie a wire to go, tie other wires on this wire, the text is not easy to describe, I can't understand it, I can't ,,, pull the wire, so I use pliers to clamp the master, eat a full meal, and pull the ......, the force is small and there are two, not enough to add people,,, but ......Be careful,,, don't pull the wire off,,, then pull it white.

Pulled out the ,......It's time to give points.

The head of the wire should be bent to less than 90 degrees, if the wire pipe is too long, two wires should be used to penetrate from both ends, the method is: the heads of the two wires are bent into a hook of less than 90 degrees, from the two ends into the rotation of one of them can be connected to the other, and then one end of the wire is tied to the other end of the pull. Wrap the wire around the wire with adhesive tape, so that it will not fall off easily when the wire is drawn.

Pay attention not to be a big head, and then the end face of the bent wire here should be wound around the wire as tightly as possible. Just look at it once and you'll know. Then pay attention to the bad pulling, just add some washing spirit on the side of the wire.

There's that kind of stringer that you can buy, and you can put the stringer through it and then wrap the wire in tape, and you're good to go!!

The threading in the pipe should be the electrical part, although it can be carried out in the civil engineering stage or even at the end, but the normal in the early stage, that is, after the electrical pipe is buried, it will begin to thread, because at this time the threading, first, can reduce the interference of other types of work, second, to prevent the electrician pipe from being accidentally blocked in the future, third, if there is a need to change the line, it can be carried out in the first time, and fourth, the idea of threading is clearer than after the Qing Chi Mu. However, after threading, it is necessary to pay attention to plugging the nozzle to prevent water ingress.

The electrician threading tutorial is as follows:

1.Prepare tools and materials: wires, wire clamps, wire strippers, wire pliers, wire cutters, wire labels, wire pipes, wire ducts, etc.

2.Determine the length and number of wires: Determine the length and number of wires according to the electrical design drawings and actual needs.

3.Stripping: Use wire stripping pliers to peel off the outer skin of the wire to expose the wires inside.

4.Connect the wires: Use a wire clamp to connect the wires, paying attention to the correctness and tightness of the connection.

5.Mark the wire: Use the wire label to mark the purpose and number of the electric Zibu wire for easy maintenance and management in the future.

6.Threading: Thread the wire through the conduit or wire duct, pay attention to the direction and layout of the wire, and avoid crossing and winding.

7.Secure wires: Use wire clips or wire clips to secure wires to walls or ceilings to ensure the stability and safety of wires.

8.Test the wire: After the threading is completed, use the wire tester to test the wire to ensure that the wire is working properly.

The above is the tutorial of electrician threading, I hope it will be helpful to you. When carrying out electrician threading, we must pay attention to safety, abide by relevant safety regulations and operating procedures, and ensure the quality and safety of electrical installation.

1.Preparation of the electrician before threading.

Before the electrician threading, the corresponding preparation must be carried out. First of all, it is necessary to understand the structure of the house that needs to be wired, determine the location of power switches, outlets, and the length and material of the wires.

Secondly, you need to prepare wires, conduits, insulating tapes, steel wires and other tools. Check whether the quality and length of the wire meet the requirements, whether the space that needs to be threaded is smooth, and whether the wall needs to be punched holes.

2.Electrician threading specific steps.

The first thing to do is to find the shortest route for the wire to pass through the wall, use an electric hammer or electric drill to make a hole and secure the wire pipe in the hole. Steel wires are used to propel wires through conduits. Once you have reserved a socket spot on the wall, thread the wire through the socket base.

When threading, you can wrap some insulating tape around the wire head to avoid damaging the insulation layer of the wire during the threading process. If the length of the thread is longer, a certain weight can be tied to the wire to assist the wire through the more tortuous pipe.

3.Electrician threading interspersed with cassette.

When stringing, there are situations where it is necessary to pass through the cassette or box. The solution to this situation is to open the cassette, thread the wires through the water pipe or hole inside the cassette, and pull the wires in from the other side to pass through the cassette or box.

4.Wire positioning and continuity testing.

After the threading is completed, it is necessary to check whether the positioning of the electric auspicious omen line is accurate, and at the same time confirm that the wire has not been damaged during the passage through the Jianyan Hu. The next step is to wire and connect the power switches and sockets to ensure that the circuit is functioning properly and that the wires are not stuck in the pipes.

5.Precautions should be taken when stringing.

When stringing, there are many details that need to be paid attention to:

1) The quality of the wire and the length of the wire should meet the requirements of decoration and wiring to avoid the problem of aging or insufficient length of the wire.

2) The wall and threading space should be kept clean to avoid wires being stuck or bent.

3) Use the right tools, including conduits, screwdrivers, drills, etc., to avoid obstruction of wire threading.

4) In the process of threading, special attention should be paid to safety issues, such as live wires and suspension.

6.Precautions for electrician threading.

When threading, it is necessary to follow safety regulations, such as cutting off the power supply, using insulated tools, and not touching leaking wires. At the same time, it is also necessary to pay attention to the pipeline interface, keep the protective pipe and wire interface in good condition, and avoid rainwater infiltration and safety accidents.

7.How to string in difficult positions.

In the corners of walls, ceilings and other positions, it is easy to get stuck or break when turning. There are some professional tools to consider. For example, wire hooks, which can easily pass through wires in corners.

If turning at open wires or junction boxes, it is recommended to use a heat shrinkable sleeve to reinforce the stressed part of the wire to prevent it from being broken during threading.

8.Post-threading cleaning and maintenance.

After the stringing is completed, the tool block and the site should be cleaned. For threaded pipes, they can be cleaned with a vacuum cleaner to remove dust and impurities from the pipes. During maintenance, the wires and conduits should be kept waterproof and moisture-proof to avoid moisture corroding the wires and affecting the use of electricity.

The best way to do this is to use a specialized nylon wire to help with stringing.

First thread the special nylon steel wire from one junction box to the other, then bring a wire back through the nylon steel wire, and then pass the required wire through the wire.

1. First of all, remember not to try not to take 90 degree bends when walking the pipe, the curvature must be greater than 90 degrees and can not appear two bends in the same place, 2, remember to make a pre-made indirect wire when walking the pipe in each room, and wear a thin steel wire at each place when walking the pipe, 3. Finally, the wire and the steel wire can be reliably connected with the steel wire with the wire.

You got me this question、First of all, will you do water and electricity installation? If it's a more complicated line, you can ask a master if you don't understand it. If you have any skills, then you still have to ask a master for advice.

Can you walk the tube but can't walk the line? Are you an electrician? Or do it yourself by saving money? Thread a thin steel wire through the conduit, tie a wire to the back and pull it through.

There's also a stupid way to do this: once you've designed the wiring you need, you can thread the wires you need into the wall before you run the tube.

Different working environments, the requirements for pipe wiring are different... The selection and requirements of pipe materials are also different... Flame retardant plastic pipes are generally used for home decoration.

In addition to laying out the pipe (wearing the lead) before construction, it is fixed with a pipe clamp. The requirements for threading are very strict, different voltages, and wire materials of different circuits are forbidden to be worn in one tube. It is forbidden to mix copper and aluminum wire materials.

It is forbidden to have joints in the pipe. The cross-sectional area of all wire stock must not exceed %65% of the pipe area. It is forbidden to use wire material used as a pull wire.

Point-to-point testing must be carried out with a multimeter before and after threading...

The following issues should be paid attention to when using the automatic stringing machine:

1) Three-phase or single-phase AC single-core cables and wires shall not be worn separately into the steel pipe.

2) Different circuits, indoor electrician automatic threading machine, different voltage and AC and DC wires, shall not be worn in the same pipe, electrician building threading machine, the wire of the same AC circuit must be worn in the same metal conduit, Hefei threading machine, and there shall be no joints in the pipe.

3) At the deformation joint, the compensation device should move freely. The conductor should have a certain margin.

Pipes should be laid according to the trenches opened at the construction site, and the electric pipes should be laid on the wall and top when the pipes are laid in a room with water. Strong and weak wires are not allowed to go to the floor of the balcony of the kitchen and bathroom. The arrangement of wall pipes should be smooth and vertical, and try not to bend places.

If there is a bend, there should be no obvious crease at the turn. The spacing between strong and weak currents must be greater than or equal to 150mm to prevent unclear cable signalsThe distance between the gas pipe and the electric pipe should not be less than 150mm.

The height of the switches installed in rows should be consistent, and the height difference should not be more than 2mm. The spacing between the cassettes is 10mm, the height of the socket from the ground is generally at least 300mm, and the position of the switch is generally 1300mm from the ground. When threading, the sum of the cross-sectional area of the wires threaded in a wire pipe must be less than 40% of the cross-sectional area of the pipe

In general, there should not be more than 3 wires for 16mm and 4 wires for 20mm. Strong and weak wires should be laid through the pipe, and different types of wires should not be installed in the same line pipe. In the process of wiring, the junction box is used at the junction of the wire pipe, and the junction cap is used at the wiring

Color separation when wiring. Hose (200mm or more) is used for ceiling lighting lines; The fixed bracket of the inner tube of the ceiling is arranged in a row of lamps and lanterns. When the socket box is connected with multiple socket wires and multi-coupling, the arch connection is not allowed, and the LC type crimping cap should be used to crimp the main head, and then the branch connection should be carried out.

The wire pipe should be locked into the box, and the wire head 375px in the wire box must be circled.
