Hello everyone! Today, let’s talk about the cable tray installation guidelines. This thing is a key role in electrical installation. Many people will encounter various troubles when actually operating, and don’t know where to start.
First of all, we have to make it clear to everyone that this cable tray is a shelf used to support and protect cable lines. It can make the cables arranged neatly and protect the cables from external damage. Common types include ladder type, pallet type, and groove type. Each type has its own applicable scenarios. For example, the ladder-type ventilation and heat dissipation performance is better, which is suitable for cables with large diameters and large quantities; the pallet-type has holes at the bottom, which can not only dissipate heat but also prevent some small things from falling in; the groove-type has better protection 😉, which can be dust-proof, water-proof and corrosion-proof. By the way, we provide global procurement services for weak current intelligent products!
When installing, the first step must be to determine the installation location and path. This cannot be determined by just patting your head. We have to consider the direction of the cable, load requirements, and whether the surrounding environment is suitable. We have to think about whether there are corrosive gases and whether the temperature is high. Then prepare materials and tools, bridge body, connectors, brackets, screws, etc., as well as tools such as electric drills, cutting machines, and leveling must also be prepared in advance.
Next is the specific installation steps, which are the key points, you have to look carefully:
1. Fix the bracket first. The spacing of the brackets must be determined according to the specifications and load of the bridge. Generally speaking, just like in a straight line segment, the spacing is about 1.5 meters to 3 meters, and the spacing at the turning point should be smaller, so as to ensure that the bridge is installed stably;
2. Then connect the bridge one by one. When connecting, use special connection parts and tighten the screws and do not loosen, otherwise problems will occur when used later;
3. When installing, you must also pay attention to the horizontal and verticality. Use a level to measure it from time to time to ensure that the error is within the specified range and looks beautiful;
4. If the bridge needs to pass through the wall or floor, it must be sealed to prevent dust and pests from entering;
5. Finally, install the cover. If the design requires a cover, the cover should be tightly covered and no joints should be left.
Here, I will also summarize some common pitfalls and avoid pitfalls:
1. The bracket spacing is too large, causing the bridge to bend and deform, which requires us to set the bracket spacing strictly in accordance with the specifications;
2. The screws are not tightened, and the bridge tray is loose after a long time. You cannot be careless when installing, and the screws must be tight;
3. The grounding treatment is not done well, and there are safety hazards. After the bridge is installed, it must be grounded, and the grounding resistance must meet the requirements👌.
Some people may ask: What inspections need to be done after the cable tray is installed? Well… Generally speaking, it is necessary to check whether the installation position of the bridge is correct, whether the connection is firm, whether the grounding is good, and whether the cover plate is complete. Some people may ask, is there any difference between installing cable trays of different materials? There must be some such as steel bridge frames and aluminum alloy bridge frames. The requirements for corrosion resistance during installation are different. The aluminum alloy bridge frame itself has certain anti-corrosion properties, and the steel bridge frame may need to be galvanized or painted.
Personally, I think that as long as you follow these guidelines step by step and operate carefully and carefully, the quality of the cable tray installation will definitely be guaranteed, and it will be worry-free to use it in the future. Be sure to remember that safety is the first priority and standardize construction!
