MHY32 coal mine polyethylene insulated steel wire armored PVC sheathed communication cable can be divided into six series of products according to the purpose and scope of use of communication cable, namely, urban communication cable (including paper insulated urban telephone cable, polyolefin insulated polyolefin sheathed urban telephone cable), long-distance symmetrical cable (including paper insulated high and low frequency long-distance symmetrical cable, copper core foam polyethylene high and low frequency long-distance symmetrical cable and digital transmission long-distance symmetrical cable), coaxial cable (including small coaxial cable, medium and small coaxial cable), submarine cable (including symmetrical submarine cable and coaxial submarine cable), optical fiber cable (including traditional cable type, ribbon array type and skeleton type), radio frequency cable (including symmetrical radio frequency and coaxial radio frequency).
Communication cable production plants are distributed throughout the country. In addition to producing long-distance communication cables and local communication cables, China has also made significant progress in the production of fiber optic cables and polyolefin insulated comprehensive protective layer all plastic local communication cables. Many domestic manufacturers and research institutions have introduced technology and equipment from abroad to start production. Every year, a small amount of polyolefin insulated polyolefin sheathed all plastic local telephone cables are sold to Hong Kong, Macau, Southeast Asia, and the Middle East in China.
A communication line consisting of multiple insulated wires or conductors that form a cable core and have a sealed sheath on the outside. Some also have an outer protective layer outside the sheath. There are various laying methods such as overhead, direct burial, pipeline, and underwater. Divided by structure into symmetrical, coaxial, and composite cables; Divided by function into field and permanent cables (underground and submarine cables). Communication cables have a wide transmission frequency band, large communication capacity, and are less susceptible to external interference, but are not easy to maintain.
Cables for communication, television and radio programs, data, and other electrical signals. It is made up of twisted wires that are mutually insulated from each other. Compared with overhead open lines, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less susceptibility to natural conditions and external interference
