Wire and cable duct steel

When electrical work is often necessary to deal with soft wiring. It can be made of a durable, wear-resistant material, but flexible fibers will not allow you to easily draw a line in difficult conditions with obstacles. The way out for the wire and cable can become a way out, which acts as a kind of rigid rod and makes it possible to make the installation in parallel with the pushing of the contour.

General information about broaching

In fact, it is a tool used in the process of electrical installation operations. By itself, it does not act as an element of the communication infrastructure, so even in the course of operation it does not affect the quality of the work of the laid line. The task of broaching is only in the direction of the target cable to the destination - usually this technique is used by Internet service providers who deal with a flexible twisted pair. In practice, broaching for wires and cables can be realized by improvised means. Again, the main goal is to provide rigidity in the conduct of the power line. However, tool-assisted devices are rarely useful, if we are talking about long channels of several tens of meters. Accordingly, it is necessary to approach correctly and to a choice of a means of broaching from an existing assortment.

Main characteristics

In the market the material is represented by bays with different characteristics. The main parameter in the selection should be the length mentioned, because its shortage will make the adaptation useless. Bays can have a range of this value from 5 to 70 m. This is an average corridor, since there are also non-standard sizes. As for the diameter, it is on average 3-6 mm. The optimal combination of characteristics, which the standard broach for wires and cables has - 50 meters with a diameter of 3.5 mm. This format is suitable for most professional work operations, and for household electrical wiring. True, at home, often cost and models length of 10-20 m, and in industries and industry often requires the use of high-strength thick broach with a thickness of at least 5 mm. But it depends on the specific conditions of the work.

Features of steel broaches

An important characteristic is the material of the broach production, which in many ways determines its working properties. In this case, the steel device is considered as a universal option for different purposes. These broaches are usually a wire or tape product with optimum stiffness. Often, the rod is packed into a nylon sheath, which gives the surface sufficient glide. At the same time, the base retains its elasticity necessary to overcome barriers. It is important to note the property of longitudinal flexibility, which is possessed by such a broach for wires and cables. The steel band base just provides this effect, thanks to which the master can easily overcome the bends on the way to the fixation point, but at the same time remain steadfast in other directions. This, for example, can not be achieved when working with fiberglass or completely nylon strands. However, products from other materials also deserve attention.

Stretching out of other materials

Models of fiberglass are also attractive in their special qualities. For example, modern plastic provides a high degree of rigidity. This allows not only to keep the line to the desired point, but also, if necessary, to push mud accumulations in problem areas. At the same time, the original structure of the plastic remains. Elasticity of the same level, for example, is devoid of metal pulling for wires and cables. Due to this quality, the glass fiber does not deform and confidently adheres to the assigned course when laying. But there is a significant disadvantage for such broaches - at high loads on bending they break.

Also worth noting is the use of auxiliary materials optimizing the quality of the broach. Nylon has already been mentioned, but in some cases it may also be necessary to incorporate into the structure of tear-resistant components, thanks to which the wire pulling itself and the cables themselves are strengthened. Kevlar and its fibers can be the optimal solution of this type. For this reason, it is often used as part of a braided shell and protective corrugation for wiring.

Auxiliary means for broaching

In addition to materials that are part of the broach structure, it is worth noting the importance of additional accessories, which also increase the efficiency of the workflow. For example, among them one can distinguish tips, probes, notches, loops, etc. Quite an interesting device is a special roller, with which it is convenient to carry out pulling for wires and cables. Electric installation in this case is realized due to forward movements with the use of winch force. There are hydraulic, mechanical and electrical devices that can even automatically pull long distances. An even more technological solution can be the use of a receiver that determines the presence of objects in the path of the roller. Based on the analysis, the device gives the appropriate command to bypass the equipment of the winch.

Manufacturers

Virtually all manufacturers involved in the production of electrical equipment, and offer cable traction. Among domestic manufacturers it is possible to allocate production "Elix-cable" which differs both an attractive price list, and quite good technical characteristics. But if you need a broach for wires and cables in the professional field, it's better to contact the world famous brands Estiare and Rexant. The products of these manufacturers are known for their balanced working properties and extensive options for supplementing accessories.

Conclusion

Using the broach gives the electrician a lot of advantages. With this equipment, you can implement a gasket in minimum time, without damaging the same twisted pair. In addition, the drawing for wires and cables can be organically incorporated into the corrugated shell. In this case, it increases its responsibility in overcoming obstacles, so it is necessary to stock up in advance with suitable tips for the size and calculate the parameters of the base itself. After the completion of working activities, it is necessary to exclude the draw from the line, especially if it is made of metal.
