Arches and corners

Arches and corners are used as connecting elements in cable routes. They are used for aesthetic and convenient electric power distribution in workshops, factories and industrial plants. They are used on all kinds of bends and curves, allowing for cable routing in different directions.

Arches and corners - where are they used?

The term cable routes refers to the wires that supply electricity in the premises, as well as the covering elements. The cables are placed in various types of cable trays with different cross sections. They are not recessed in the wall, but led through the external routes. Thanks to that the cable routes can be serviced much easier. This solution can be found both in industrial properties, as well as in public buildings.

Cable routes are usually installed under ceilings. They are suspended using channel sections and rods anchored in the ceiling. Depending on the required connections, vertical or horizontal bends and corners are used. These types of cable routes are never completely straightforward - after all, there is a need to avoid obstacles or to bring the installation to many rooms in the building. As a result, a variety of connection elbows or vertical bends are used to change directions - i.e. to turn the installation around.

Such constructions must be adapted to work in harsh conditions - characterized by resistance to corrosion and high temperatures. Therefore these elements are very often covered with galvanized coatings. For use in the food industry, protection against acids is also important. The same material should be used for the entire length of the installation - both straight sections and in all kinds of changes of direction with bends and corners - to ensure that the installation really is robust.

Arches and corners - construction

Bends and corners are the name of all kinds of branching elements of cable routes, thanks to which it is possible to bend the cable route. These can be various arches 90 degrees, articulated arches or vertical bypasses. These elements must be perfectly matched to the dimensions of the led trays - ensuring a tight and solid connection. Such elements have numerous openings that enable their embedding in the channel and firm connection with bolts and screws. For a stable and strong connection connectors are used - that is elements made of steel used for joining parts within cable routes.

Elbow is the name used for corners at an angle of 90 degrees. In this case, there is a change in the direction of the cable at a right angle - allowing you to leave the installation, for example, to other rooms. 90 degree bend should be characterized by the volume enabling the cable to be laid in the track with as much slack as possible, minimizing stress.

Articulated arches - unlike elbows or 90 degree bends - consist of several parts made of steel sheet. This allows a much wider range of adjustment of the joint angle in the cable routes. Such articulated arch allows for the best possible adjustment of the route to a particular room.

Vertical bypass, on the other hand, is a specific form of arches and corners. Its purpose is not to change the direction of the route - but only to bypass an obstacle. This type of elements can usually be installed interchangeably as upper or lower bypasses.

Selection of corners and bends

The offer of connecting elements for cable routes is very wide. When choosing individual elements, you should pay attention not only to the issues of cross-section or sheet thickness. It is also important what kind of cables are in the installation. It should be remembered that data communication cables require different parameters than power cables. The use of connectors has a very large impact on the durability of cables inserted into cable ducts. During construction and planning of these systems it is important to minimize the possibility of stresses. The greater the angle of twist - the greater the stress, which can lead to cracks in the cables. Therefore, a very important parameter is the volume - indicating how much working space you can spread the cables in the corner.
