Problems solved by technology

The electromagnetic field of the symmetrical communication cable is in an open state. At high frequencies, the attenuation and loss of the loop are relatively large, and the mutual interference between the loops and the external interference are relatively large. It is difficult to increase the transmission frequency and capacity. The former is generally used at a frequency of several Hundreds of kilohertz; the frequency of the latter is much higher than that of the former, but there is a problem that the manufacturing cost is more expensive

Abstract

The invention discloses an anti-interference symmetric communication cable which is formed by wrapping a plurality of cable cores through insulation outer layers. The cable cores are symmetric, every two cable cores are regarded as a set to be wrapped by the insulation outer layers and vertically symmetric, and a barrier is arranged between every two vertical cable cores wrapped by the insulation outer layers. According to the anti-interference symmetric communication cable, the anti-magnetic barriers made of composite materials are arranged between upper sets of cable cores and lower sets of cable cores to play a good role of anti-electromagnetic interference, two arc blocking heads are integrally formed on each barrier to better fix the cable cores, and stable work of the cable is guaranteed. Barium sulfate is added in the materials of the barriers, so that good diamagnetism is achieved, silicon nitride materials have good temperature variation resistance, weather resistance of the cable is guaranteed, yttrium oxide effectively enhances zirconium oxide, and insulation property is better.

Description

technical field [0001] The invention relates to a cable, in particular to an anti-interference symmetrical communication cable. Background technique [0002] Communication cables refer to cables that transmit telephone, telegraph, fax documents, TV and radio programs, data and other electrical signals. It consists of more than one pair of mutually insulated wires twisted together. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less affected by natural conditions and external interference. [0003] Communication cables can be divided into long-distance communication cables for long-distance transmission and regional communication cables for shorter-distance transmission according to their uses. Long-distance communication cables can be divided into relay communication cables for connection and trunk long-distance cables (or trunk communication cables) for int...
