Communication cable, as a transmission medium, is a necessary equipment for completing information projects. Unsuitable fiber optic cable is likely to affect the quality of the whole project. So, how to choose the right fiber optic communication cable?
Power armored cable is a power cable equipped with a hard armor layer outside the conductor. The armored structure can effectively protect the conductor from external damage. This type of cable is often used for buried laying in harsh environments. It is safe, stable and reliable, resistant to animal bites and acid corrosion.
Fiber optic cable is mainly used to realize signal transmission in communication lines. According to the purpose of use can be divided into power fiber optic cable, communication fiber optic cable, outdoor fiber optic cable, mining cable and so on. So what are the differences between power fiber optic cable and communication fiber optic cable?
1. Single-Core Cable Sheath End Grounding Method, Why Must Be Installed Along The Cable Laid In Parallel With The Return Line?
In the metal sheath end of the grounded cable line, ensure that the induced voltage in the sheath does not exceed the allowable standard.
Must be installed along the cable line parallel laying of a conductor, and the two ends of the conductor grounded, this conductor is called the return line.
In recent years, the technology in the photovoltaic industry is developing faster and faster. Such as the power of a single module is getting bigger and bigger. And the current of the string is getting bigger and bigger. With this comes the popularity of PV cable. System design and component-appropriate … Read more
In a modern DC transmission system, only the transmission link is DC, the generation system and the consumer system are still AC. At the sending end of the transmission line, the AC power from the AC system is sent to the rectifier via the converter transformer in the converter station. Which changes the high-voltage AC power into high-voltage DC power and sends it to the DC transmission line.
Satellite TV can reach the most remote corners of the earth, where there are no usual providers and broadcast towers. The available compact systems can be installed anywhere. The satellite dish provides it with color and a clear picture. The common cable used for satellite TV is satellite coaxial cable. … Read more
Armored fiber optic cable is a kind of fiber optic with a metal armor sheath wrapped around the core. This layer of armor makes the cable resistant to strong pressure and stretch, and also protects it from harsh environments. Armored fiber optic cables are stronger, more reliable and more durable than ordinary fiber optic cables.
The material of the cable also plays a decisive role in the quality of the cable. In the past, plastic cables were used more often, but gradually rubber cables began to replace plastic cables. So is it because rubber cable must be the best. Here let ZMS cable company’s editor explain the difference between rubber and plastic.
According to the railroad station in Nanjing, at 18:20 on August 8, the Nanjing Yangtze River Bridge highway bridge below the attached place cable burst into flames and smoke, the fire department and the railroad units concerned quickly disposed of, affecting some trains late. The cause of the incident is under investigation.
