In today’s era of networking and electronic development, the requirements for Harsh (hard environmental cabling) are getting higher and higher. The so-called Harsh refers to laying and using cables, optical fibers and other wiring systems in a relatively harsh environment. Harsh environments, including deserts, deep seas, mines and other places! There is still a big gap between it and ordinary environmental wiring .
Next, let’s talk about the key content of Harsh in different modules. First of all, the material selection module must be made of materials that can withstand high and low temperatures, chemical corrosion, radiation resistance and other harsh conditions. Materials such as special plastics and synthetic rubber are a good choice. For example, corrosion-resistant polyimide is very competent! Generally, the performance attenuation of these materials at high and low temperatures is at least 30% lower than that of ordinary materials, which is very impressive.
Secondly, the wiring design module. In the design of harsh environment wiring, we cannot simply consider wiring methods like ordinary environments. For example, in a windy and sandy environment like the desert, you must pay attention to burying the cables at an appropriate depth, which can not only prevent wind and corrosion, but also ensure a relatively stable temperature. In some particularly dangerous mines such as gas, explosion-proof and anti-static wiring designs must be used. Professionals must design and plan the direction and curved arc of the wiring. Generally, the bending degree of a cable must not exceed a specific angle, as it may affect signal transmission. Also, be sure to ensure that the cables are connected firmly to various electrical components. Generally, the stability of this connection must be done by a special connection method, which is more than twice the sturdiness of the ordinary connection.
Installing the module. The installation process requires a very rigorous construction. When installing in harsh environments, some advanced tools will be used, such as high-temperature hot melt guns, underwater installation robots, etc. For example, when installing in deep sea, underwater robots can be installed at a certain depth in the bottom of the water, which is very accurate and convenient! However, the installation workers must be well trained! If the worker makes any installation errors, it may be a big deal. It is necessary to always check all parameters during the installation process, the tensile degree, temperature and other aspects of the cable must be controlled. Generally, the tensile strength of a cable must be maintained within a reasonable range.
Then maintain the module. This maintenance is also a long and arduous process. It is crucial and necessary to formulate a plan for regular inspection and maintenance of the wiring system! A monitoring system must also be installed to monitor the signal transmission quality, temperature and humidity of the wiring system in a timely manner. Any minor problems can be detected and repaired as soon as possible. Moreover, the fault plan must be handled in a targeted manner. Different harsh environments must have different solutions! For example, for a wiring failure problem in a desert, the fault range must be determined first. It may be caused by wind corrosion to cause the cable skin to become thinner. Which special repair material should be used to repair it. Repairing the signal strength can greatly improve it. After all, the maintenance conditions in the desert area are limited
OK, let’s answer some common questions here. Q: Can ordinary wiring be used directly in harsh environments? Answer: This is a big mistake! Ordinary materials can not withstand deterioration environments such as high and low temperatures, corrosion, etc. Harsh Environment Cabling, and may be damaged in a short time. Question: Is the wiring cost of harsh environment much higher than usual? Answer: There are improvements, but you consider cost-effectiveness and stability. In the long run, it is reasonable. After all, avoid a lot of troubles of frequent cable replacement and other fees!
Q: Is it okay to just wrap some electrical tape when the wiring connection is loose? Answer: At most, special connection methods and materials must be used for special environments, otherwise their connection reliability will not be sufficient! There is a problem with signal transmission and the risk of failure is quite high! In addition , it provides global procurement services for weak current intelligent products ! Overall, in short, Harsh actually plays a huge and lasting role in ensuring service for various smart devices, communications, etc. in harsh environments. It is certainly said that with the changes in the environment and the development of science and technology, its technology and experience will definitely become more and more mature in the future. I hope that this wiring system will have more development and utilization!
