We seldom encounter the problem of Jinan cable bridge in our life, because we use Kaichen bridge, which has good technology, good quality and long service life.
If the cable bridge fails, there are four common types:;
1. The whole cable is burnt or one phase is burnt. This type of fault will cause the current relay on the distribution cabinet to work. The cable was seriously damaged at the fault.
2. All phases of the cable are short circuited. Similarly, this type of fault causes the current relay and voltage relay on the distribution cabinet to work, and the cable is severely damaged at the fault point.
3. Only one phase of the cable bridge is open, the current relay works, and the damage of the fault point is relatively light but obvious. It may be caused by large phase current flow or cable quality.
4. There is a short circuit inside the cable, and no trace can be seen on the appearance. This kind of fault is generally caused by the cable quality, which is relatively rare.
Therefore, when choosing Jinan cable bridge, we need to find a strong manufacturer. Only with good technology can we build a high quality bridge, only with good quality can we make the bridge have a long service life.
There are many waist shaped holes at the bottom of tray cable trough, which is convenient for heat dissipation and widely used in petroleum, chemical industry, electric power, light industry, television, telecommunications and other fields. The utility model has the advantages of light weight, large load, good air permeability, beautiful appearance, simple structure, convenient installation, etc. It is not only suitable for the installation of power cables, but also for the laying of control cables.
Cable trough is a completely enclosed cable trough, which is not conducive to heat dissipation. It is suitable for laying computer control cable, communication cable, thermoelectric cable and other high-sensitivity systems, and has good effect on shielding interference of control cable and cable protection under severe corrosion environment.
Ladder type cable bridge has the characteristics of high strength, light weight, low cost, beautiful appearance, convenient installation, good air permeability, etc. Generally, it is suitable for laying cables with larger diameter, especially for laying cables with high, low voltage and large load. The bottom of the ladder is like a staircase, with baffles on the sides. Use ladders where there is a lot of dust so that the dust doesn't build up.
Many people are frustrated when they don't know how to install the cable tray.
(1) Bridge: the total length of various types and specifications of bridges shall be calculated separately. In addition to the size and length of the bridge, the number of bridges is also obtained, and an additional margin of 1-2% is increased.
(2) Columns: if columns of the same specification are used, the number of columns can be obtained by dividing the total length of the bridge frame by the uniform column spacing, and then the remaining number can be increased by 2-4%. If the column specifications are different, separate statistics are required.
(3) Support: divide the total length of the bridge by the uniform spacing of the supports, and then increase the margin by 1-2%, i.e. the total demand.
(4) Other parts: multiply the number of major parts by a certain proportion (depending on the factory) to obtain the total number.
The above are some common faults of Jinan cable bridge and some installation methods of cable bridge. I believe that you can have some understanding of cable bridge through the description of this article, and hope the above content can help you.
