The correct matching of industrial galvanized u-shaped trough and cables is the key to ensure the stable operation of the electrical system and avoid safety hazards. From the determination of cable specifications to the matching of cable trough models, each link needs to be carefully considered. The following will analyze the key points in detail from multiple dimensions.
Before matching, the first task is to clarify the purpose and characteristics of the cable. Cables with different functions, such as power transmission lines, signal control lines, communication data lines, etc., have different working principles and performance requirements. Power transmission lines are responsible for power transmission, and their current carrying capacity and voltage resistance level need to be paid attention to; signal control lines focus on the stability of signal transmission, and have high requirements for shielding performance and anti-interference ability; communication data lines focus on transmission speed and accuracy. Only by knowing the specific purpose of the cable can we provide accurate direction for subsequent matching selection.
The specification parameters of the cable are an important basis for selecting the adapter cable trough. The thickness of the cable directly affects the size of the cable trough. If a cable that is too thin is matched with an oversized cable trough, it will not only waste space, but also cause the cable to shake in the trough, increasing the risk of wear. On the contrary, if a cable that is too thick is forced into a cable trough that is too small, it is easy to cause the cable insulation layer to be squeezed and damaged, or even cause a short circuit. In addition, the insulation material of the cable should not be ignored. Cables with different insulation materials have different heat resistance and flame retardancy, which need to be matched with the material properties of the cable trough to ensure that both can maintain good performance in extreme environments such as high temperature.
The material and structural characteristics of the industrial galvanized u-shaped trough determine the type of cable it is suitable for. The galvanized material gives the cable trough good rust and corrosion resistance, and is suitable for harsh industrial environments such as humidity and corrosive gases. However, for some cables with extremely high requirements for electromagnetic shielding, a simple galvanized cable trough may not meet the needs. At this time, a special cable trough with a shielding layer needs to be selected. The wall thickness of the cable trough affects its bearing capacity. If there are many cables and they are heavy, you need to choose a cable trough with thicker walls and higher strength to avoid deformation of the cable trough due to insufficient load-bearing capacity, which in turn damages the cables.
The laying method of the cables will also affect the matching of the cable trough and the cables. For cables laid openly, the cable trough should be neat in appearance, easy to install, and convenient for later maintenance; for cables laid concealed, more attention should be paid to the sealing and concealment of the cable trough. At the same time, different laying paths, such as straight-line laying, turning laying, and laying through walls and boards, have different requirements for the shape and accessories of the cable trough. For example, in lines with frequent turns, it is necessary to match the appropriate elbow accessories to ensure smooth transition of the cables at the turns and reduce bending damage.
In the actual matching process, it is also necessary to consider the reserved space. During the operation of the electrical system, the cables will generate heat due to the passage of current. If the cables in the cable trough are too crowded, the heat cannot be dissipated in time, which will accelerate the aging of the cable insulation layer, reduce the service life, and even cause fire hazards. Therefore, when choosing the size of the cable trough, a certain amount of space should be reasonably reserved according to the number and specifications of cables. It is generally recommended to reserve 20% - 30% of the margin to ensure that the cables have sufficient heat dissipation space and activity space.
Detailed processing during the installation process is also an important part of correct matching. When laying cables into the cable trough, avoid entanglement and crossing between cables. They should be arranged neatly and fixed with cable ties or wire clamps. For the connection of the cable trough, ensure that the connection is tight to prevent the cable from escaping from the gap or foreign objects from entering the cable trough. At the same time, at the entrance and exit of the cable trough, a wire sheath should be installed to protect the cable from wear and tear and extend the service life of the cable.
After the cable is matched with the industrial galvanized u-shaped trough, subsequent inspection and maintenance are indispensable. Regularly check the status of the cables in the cable trough to check whether there are abnormal conditions such as damage to the insulation layer, discoloration due to overheating; check whether the cable trough is firmly fixed and whether there is any looseness or deformation. Once a problem is found, it should be dealt with in a timely manner, such as replacing damaged cables and reinforcing the cable trough. Through continuous maintenance, ensure that the electrical system is always in a safe and stable operating state.
