The cable tray shall be selected according to its own needs and shall not be used blindly. This will not only not ensure normal use, but also shorten the service life of the cable tray. Now let's talk about the short circuit, expansion and contraction of Shandong cable tray.
The common problem in the use of cable tray is short circuit. Short circuit may be caused by internal short circuit of the cable, or it may be caused by burning of the cable. Generally speaking, it is caused by low cable quality.
In addition, there will be expansion and contraction problems. Because the change of ambient temperature, such as steel cable tray, will show thermal expansion and cold contraction. The role of outdoor cable tray is greatly affected by temperature, so pay attention to temperature changes.
The second is to maintain the cable tray. It includes two aspects, namely cleaning and protection.
When cleaning the cable tray, it is required to use a relatively pure and soft cloth to wipe. It must not use a wet cloth or some acidic cleaning agent to wipe, otherwise it will corrode the cable tray or cause electric shock. Cleaning the dust on the surface of the cable tray is only one aspect of maintaining the cable tray.
If you want to better maintain the cable tray, you also need to use light wax for maintenance. In terms of protection, it means that the long-term use of the cable tray will cause the appearance to be not bright, so it needs to be waxed. If there are some problems with the cable tray in use, professional protection personnel should be sought for protection.
