Cable tray plays an important role in our daily life. But it often shows some problems and brings chaos to our life. What problems will cable tray encounter? How to solve it? Jinan cable tray manufacturer explains for you.
Possible defect: All parts of the cable seem to be short circuited. Such defects may cause the current relay on the power distribution cabinet to act, and the cable damage is very serious;
There will be a defect: short circuit inside the cable. This type of defect is usually caused by the low quality of the cable, and there is no trace on the outside. It seems that the whole cable is burnt out, or the cable in some place is burnt out, causing serious damage to the cable in the fault location.
The possible fault is that there is only one short circuit in the bridge, and the cable at the fault is slightly damaged, but there is still obvious trace. This fault may be caused by excessive current or poor cable quality. All mechanical equipment shall be inspected and maintained regularly after use.
How to repair and maintain cable bridge equipment:
1. Test and check the working condition of the balance cylinder of the cable bridge equipment and the oil circuit and connector of the oil lubrication system.
2. The sliding block of cable tray equipment rubs with the guide rail frequently, so necessary adjustment shall be made, and the lubrication quality of joints and pipes shall be checked to ensure good operation.
3. Regularly lubricate the gear parts of cable bridge equipment: due to frequent operation, the gear box and internal parts are easier to be damaged and loosened.
In addition, the bridge can be operated and grounded with reliable power. Moreover, when the bridge is grounded, the resistance at the bridge end cannot be less than 0.00033 ohms. When grounding, the bridge must be reliably connected with the grounding main line. That is, under normal conditions, the bridge can be grounded.
