Now there are many materials and equipment in life, and in the process of using electricity, the protection of wires and cables is also very important. At this time, protective belts are usually established. What are the advantages of cable protective belts? Let’s learn more about it together.
Cable protection belt advantage
1, good corrosion resistance, long service life, can be used in wet saline alkali land.
2, flame retardant, good heat resistance, can be used for a long time at 130 degrees high temperature without deformation, fire does not burn.
3. High strength and high rigidity. It is used for direct burial under the carriageway without adding concrete protective layer, which can speed up the construction progress of the cable project.
4, cable protection sleeve whether it is pipe or pipe fittings have a certain degree of flexibility, can resist the damage caused by external pressure and foundation settlement.
5. It has good anti-external signal interference performance.
6. The inner wall is smooth and does not scratch the cable. The design adopts socket type connection mode, which is convenient for installation and connection. The joint is sealed with a rubber seal ring to adapt to thermal expansion and contraction, and to prevent mud and sand from entering.
If the cable is to be stored for a long time, the following considerations should be made according to the location of the cable:
1, under the eaves. Standard LAN cables can be applied only when the cable is not directly exposed to sunlight or ultra-high temperature. It is recommended to use pipes.
(2) on the outer wall. Avoid direct sunlight exposure to the wall and man-made damage.
3. In the pipe (plastic or metal). For example, in the pipeline, pay attention to the damage of the plastic pipe and the heat conduction of the metal pipe.
4. Suspended application/overhead cable. Consider the SAG and pressure of the cable, which binding method is intended, and whether the cable is directly irradiated by sunlight.
5, directly in the underground cable trench laying, this environment is the smallest control range. The installation of cable trench should be checked regularly for dry or wet degree.
6. Underground pipelines. In order to facilitate future upgrades, cable replacement and isolation from surface pressure and the surrounding environment, auxiliary pipelines are isolated, and auxiliary pipelines are a better method. But don’t hope that the pipeline will remain dry forever, which will affect the choice of cable type.
How to protect wires and cables
first, the cable protection tube must achieve flame retardant effect, the general flame retardant level is in V0 grade, usually the cable protection tube has the performance of insulation and temperature resistance, so as to better protect the wire and cable, in order to extend the life and ensure safety;
2. The bearing capacity of the General Cable protection tube can withstand the weight of the foot, without breaking or deformation, and after the foot is stepped on, it can quickly return to its original state and remain intact without any damage;
third, select the temperature range. Generally, the working temperature of the cable protection tube can reach -40 to 125 degrees, and it can reach 150 degrees in a short time. According to the ambient temperature when the hose is working, when the temperature is high, the pressure after temperature correction must be determined according to the working pressure temperature correction coefficient of the plastic-coated metal hose at high temperature, so as to determine the correct pressure level;
four, a series of reference to this cable protection tube is of high quality, choose the quality of the cable protection tube, it is recommended to the regular manufacturers to choose.
The above is the specific introduction of the cable protection belt that we bring to you. The cable protection belt is a very important protection, which also ensures that people’s electricity is safer and the construction is more convenient.
