Leaky coaxial cable has broad market prospects Wire and cable market

With the development of China’s mobile communications construction, the leakage cable market in China continues to expand, and domestic leakage cable companies have increased year by year. At the beginning, the price of high leakage cable monopolies in foreign countries has also dropped significantly, and the profit margins of manufacturers have been greatly reduced. However, the relevant manufacturers have seen tremendous potential for development in the 3G and 4G markets. The market outlook for leaky cables is still very promising, and market competition has further intensified.

Leaky coaxial cable is used in train dispatching wireless communication systems. From a foreign point of view, not only the wireless communication of trains in railway tunnels, but also underground railways, underground streets, buildings, coal mines, and wireless communication and some remote-controlled test systems in the increasingly freeway automobile tunnels all require leaky coaxial application. cable. China has thousands of kilometers of tunnels, a large number of war preparation underground facilities, coal mines and the development of the underground railway system, also need to use leaky coaxial cable, so the development of leaky coaxial cable has a very broad prospect.

Leaky coaxial cable can be used for wireless communications in many scenarios, even in areas with electromagnetic interference or no electromagnetic waves, such as leaky guided radar, tunnels, mines, subways, and building buildings. Leaky coaxial cables can ensure uninterrupted signal coverage. As the coverage of mobile communication signals continues to expand, the number of base station stations increases, and the requirements for mobile signals in the edge areas (elevators, subways, underground buildings, high-rise buildings, etc.) continue to increase, and it is expected that the physical foam leaks the coaxial cable. There will be better development prospects. However, the requirements for cable indicators (such as VSWR, shielding attenuation, etc.) have been significantly improved, and the process and structure of cables are required to be continuously improved.

Recently, due to the impact of foreign leaky coaxial cable and RF coaxial cable products, the market share of this product in the domestic market is only 5%, and its market prospect is very broad.

At present, the integration, digitalization, and multi-channel development of railway wireless communications have become the development direction. However, due to various factors such as investment and technology, China’s railways will continue to use existing mature wireless communication systems for a long period of time. Field strength processing work still exists. There are many weak field strength processing methods in the wireless transmission range, including fiber optic repeater stations, repeater plus leaky coaxial cable, range remote station, and interval relay station. The use of a repeater plus leaky coaxial cable is an effective solution to cover wireless signal transmission in mountainous areas and has been widely used.

The application of wireless communication technology in urban rail transit is earlier. With the development of urban rail transit, the breadth and depth of the application of wireless communication technology will continue to increase.
