What problems will the cable tray encounter in use?
As an intelligent weak current system, cable tray manufacturers play an important role in our usual life. But it will also present problems as usual, which puzzles our life. Do we know what problems will appear in the cable tray?
1、 Possible faults: all parts of the cable show the appearance of short circuit, which may cause the operation of current relay on the distribution cabinet, and the damage to the cable is very serious;
2、 Problems that will appear: there is a short circuit inside the cable, which is usually formed due to the low quality of the cable, and there will be no trace on the surface;
3、 It may appear that the whole cable is burnt out, or the cable is burnt out somewhere, which makes the cable seriously damaged at the fault;
4、 The possible fault is that there is only one short circuit in the cable tray. The cable damage at the fault is light, but there will still be obvious traces.
The reason why such problems may appear is that the current is too large or the cable quality is too poor.
All mechanical equipment should be inspected and maintained regularly after use. The cable tray manufacturer will talk about how to overhaul and maintain the cable tray equipment.
1. Test and check the action condition of balance cylinder of cable tray equipment and its oil circuit and joint of oil lubrication system
2. The friction between the sliding block of cable tray equipment and the guide rail is relatively frequent, so necessary adjustment and correction shall be made, and the lubrication pipeline at the joint shall be checked to ensure good operation.
3. Regularly lubricate the gear parts of cable tray equipment: the gear box and internal parts are more likely to be damaged due to frequent operation, and there is a greater possibility of looseness.
