The electrical installation must be properly protected, even against moisture, high temperature or mechanical damage. A great choice here is a conduit , which is a corrugated electrical installation pipe . Today we will tell you whether it is better to choose a conduit with a remote control or without a remote control. We will tell you how to pull the cable.
Which solution is better? Conduit with or without a remote control?
Conduits are cabled pipes used to lay electrical cables in walls or concrete floors. You can choose a conduit with or without a remote control. It is worth knowing that the remote control makes it easier to insert the cables without dividing the pipe into sections, while the model without a remote control is most often used when the length of the cable section does not exceed a dozen or so meters. The conduit should be made of the highest quality materials, e.g. self-extinguishing PVC. It has a high mechanical resistance class and works well in various temperatures. You can choose a corrugated pipe, the working temperature of which is from minus 25 to 60 degrees Celsius or from minus 5 to 50 degrees Celsius. It is time to move on to pulling the cables.

How to pull a cable through a conduit with a remote control?
Pulling the cable through the conduit seems relatively difficult, but you can do it yourself. In this case, you need to attach the electrical wires to the remote control. You can connect one of the wires, but also remove the outer insulation of the cable, but do this very carefully so as not to damage it. It is worth covering the whole thing with tape so that the front of the wire does not catch. Remember that the remote control cannot clamp on the wires.
There is another solution. First, you need to remove the outer insulation from one wire. In the next step, you also remove the insulation, but from the core and bend it in half. In the middle, you insert a metal pilot. Of course, this is not the end of the work, because the pilot should be wrapped around the core and along the insulation. You can't pull the pilot too hard either. The last step is to connect all the elements with electrical tape. The work is similar if you want to pull several wires.
A pulling grease is very useful. It is worth choosing one that is easy to apply. Threading electrical wires using a pilot should not lead to resistance. However, if there is a problem with pulling, you can prepare a string, which you then blow into the pipe, although this is a rather risky solution. In such a case, it is recommended to insert it from the other side of the conduit, while performing rotational movements. For greater comfort, the ends of the spring can be lubricated with a little grease or dishwashing liquid. Bends can also cause problems with guiding the wires, so it is recommended to also pull a steel wire into the conduit. The pipe must also be well tensioned, but not pulled through. Pay attention to the arc itself, which should be gently sloping. You also need to choose the right pilot. It is worth choosing a carbon fiber pilot.
How to pull a cable through a conduit without a remote control?
You don't need to use a remote control to pull the cable through the conduit. A 5 mm diameter wire will come in handy. It's best to choose a model that is used to tie reinforcements on the construction site. It should be at least a meter longer than the length of the conduit. Now you need to bend the end so that it's not too sharp. The wire should be greased, then it will be easier to pull it through the conduit. We also remind you that such an installation works best when the conduit is not yet mounted in the wall. If it's different and there are additional bends, then using a remote control is justified.
Every investor should know that there are various types of cables available for pulling. You can choose a perlon cable, which is made of reinforced perlon. It has steel ends and is easy to roll up. Also worth noting is the steel cable, which is used to pull fish and tape cables. It is very solid and efficient. An interesting choice is the glass fiber model. The fiber is extremely flexible, but also resistant to bending or tearing. It also has a guiding head that makes it easier to pull the cable.
