Reducing and bypassing cable routes

Cable route reductions and bypasses have an important function in cable route systems in difficult conditions. The most popular is the reduction of a tray. Therefore, it is worth knowing its specifics, the conditions in which it is installed and the parameters that should be kept in mind when we decide to purchase such elements.

Reduction and bypassing of cable routes: characteristics

Cable route reductions and bypasses are very important elements of cable routing. The priority in making cable routes is to ensure maximum safety for the cables. This is why it is so important that the edges of the trays are blurred and smooth. The cable construction itself must also be stable. Next, it is important to install the cables correctly in the route. The cable route must always be laid in such a way as to avoid collision with other systems, for example gas, water, or telecommunications. If there is no choice and the cables have to be installed close to each other, it is always necessary to use shields with increased resistance.

It is also important to use appropriate reductions and bypasses for compacted cable routes. The basic reduction is the reduction of the cable tray, for which it is important to take into account parameters such as: material of construction, type of construction, system responsible for maintenance of operability, smaller width, larger width, height of the cable tray, as well as protection of the surface.

The basic elements are clamp or strap, which have universal application. It is worth checking which elements will be the best for a particular cable system, so that there is no doubt about the appropriate application and subsequent smooth operation. There are also used vertical rings, in which parameters are taken into account, such as: model, change of direction, height of cable tray, width of cable tray, use of side perforation, type of material used and surface protection. There are also used horizontal bundles in which the same parameters are important. Very popular is also an element such as symmetrical reduction, which is a shape used to connect two ventilation ducts, that is spiral pipes of different cross-section. Each symmetrical reduction allows you to run ventilation installation, reducing the cross-section symmetrically in the place where the axes of both dimensions overlap. Individual elements are connected by a spot weld and are additionally reinforced with a sheet metal lock.

Cable duct reductions and bypasses: Appropriate design and execution

In addition to the use of reductions and bypasses for cable routes, it is important to be aware that a route that is properly designed, constructed and installed works best for the safe routing of cables. So it is important to carefully choose installation accessories such as: brackets, hangers for connecting trays, cable ladders, ceilings, clamps, and clamps. It is also necessary to pay attention to the maximum load capacity of the routes. When calculating it, the weight of assembly components or data from the load chart are taken into account. One must be aware that the load capacity of each route depends on the width of the bracket and the length of the hanger. In order not to overload any of the sections, the centre of gravity should be placed for the cable load, so that it is as close as possible to the bracket fixing point. It is worth mentioning the cable ladders, reinforced and with high load capacity. They allow distribution of heavy cables with large cross-sections, and in the case of lighter cables, they allow less frequent use of supports and slings. This contributes to a reduction in installation time. A route based on cable ladders guarantees very good ventilation for the cables, optimal heat dissipation and keeps them clean. Cable ladders can also be used for fire protection applications, with considerable fire resistance.

No matter which reductions are used, you can be sure that every cable route will run perfectly.
