Coaxial cable (Coaxial cable) refers to a cable with two concentric conductors, and the conductor and the shielding layer share the same axis. The common coaxial cable is composed of a copper wire conductor isolated by an insulating material. On the outside of the inner insulating material is another layer of annular conductor and its insulator, and then the entire cable is covered by a sheath of polyvinyl chloride or Teflon material.
Coaxial cable can be used for analog and digital signal transmission, suitable for a variety of applications, which are important television transmission, long-distance telephone transmission, short-distance connections between computer systems and local area networks. Coaxial cable as a means of television signals spread to thousands of households is developing rapidly, which is cable television. A cable TV system can load dozens or even hundreds of TV channels, and its transmission range can reach tens of kilometers. Coaxial cable has long been an important part of the long-distance telephone network. Today, it is facing increasingly fierce competition from optical fibers, ground microwaves and satellites. The development of coaxial cables is mainly divided into four generations: the first generation started to use polyethylene material as solid core insulation medium in the middle of the 19th century; The second generation uses chemical foamed PE material as insulation medium; the third generation uses lotus root core longitudinal hole PE material as insulation medium; The fourth generation uses physical foamed PE material as insulation medium. Coaxial cable according to the structure can be divided into: leaky coaxial cable, multi-core coaxial cable, thin diameter coaxial cable, composite coaxial cable.
The development of coaxial cable industry has undergone a series of changes. As the global electronics industry entered its peak in 2000, as part of the electronics industry, the coaxial cable market has also reached its historical peak. In the following three years, as the global economic growth rate entered a trough, the coaxial cable industry also entered a downturn with the contraction of downstream demand, and only showed signs of recovery in the second half of 2003. Since 2004, the global coaxial cable industry has entered a new round of growth. With the continuous expansion of mobile communication signal coverage, the expansion of the number of base stations, and the continuous improvement of mobile signal requirements in transportation, energy, medical and other fields, the market development prospects of the global RF coaxial cable industry are still promising.
