Historical Development Of Coaxial Cables

The development of coaxial cables is mainly divided into four generations: the first generation began to use polyethylene as a solid insulating medium in the mid-19th century; The second generation is the use of chemically foamed PE material as an insulating medium; The third generation is lotus root core longitudinal hole PE material as insulating medium; The fourth generation is the use of physical foamed PE material as the insulating medium. According to the structure, coaxial cables can be divided into: leakage coaxial cables, multi-core coaxial cables, fine-diameter coaxial cables, and complex coaxial cables.

The development of the 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 size of the coaxial cable market has also reached a 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 did not show signs of recovery until 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.
