What problems should be paid attention to in the construction of fireproof cable tray wiring? Posted by : admin / Posted on : Aug 20， 2021

1. Because the diameter of Category 6 cables is thicker than that of general Category 5 cables, in order to better avoid cable coiling (especially at elbows), you must pay attention to the filling of the pipe length when designing the pipeline. , Generally, the threading pipe with an inner diameter of 20mm is appropriate to put two Category 6 wires.

2. The design of fireproof cable tray is effective to ensure suitable cable bending radius. When bypassing other wire troughs front and back, the inclination of the bend should be steep. The key is to pay attention to whether the rear cover can be tightly closed without the wind resistance cable after the cable on both sides is slack to bear the force.

3. In the process of construction and laying-out, attention should be paid to the manipulation of anti-tension. Regarding the cable with the secret medicine package, it is suggested that one worker should be placed in the middle, and the secret medicine should be placed on the self-made hanging wire rod. Workers at the construction pay-off end first pre-pulled a part of the cable from the secret medicine box for the partner to extract at the other end of the pipeline. The pre-drawn line should not be too many to avoid multiple wires from being tangled on the surface of the field.

4. After the end of the hanging wire process, the stringing pulley block left on both sides should be sorted out and maintained. When coiling the wires, they should follow the original rotation position. The diameter of the electromagnetic coils should not be too small. If possible, use scrap knots to fix them. Do not move on the cable bridge, decoration ceiling or in the cardboard box, make a good mark to remind other staff not to move and not step on.

5. When combing, bundling, and installing cables, the remaining cables do not need to be too long, and the cables do not need to be subjected to accumulated stress. The electromagnetic coils take advantage of the opportunity to arrange sideways, and the fixed ropes do not need to be tightened too tightly.

6. In all construction phases, the production process will be announced immediately. The person in charge of various projects in the building must communicate and communicate immediately. If the test results are found, the tenderer will be notified immediately, and the technical work responsibility will be carried out immediately before the start of other post-technical work types.
