Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a corrosion-resistant communication cable.
Background
A communications cable is a cable that transmits telephone, telegraph, facsimile documents, television and radio programs, data and other electrical signals. Is formed by twisting more than one pair of mutually insulated wires.
Modern cables are mostly buried deep underground, and due to environmental pollution or regional land properties, soil is often corrosive, so that communication cables are easily corroded to be damaged, and economic loss is caused.
Disclosure of Invention
In view of the above problems, the present invention provides a corrosion-resistant communication cable having excellent corrosion resistance, durability, and ensuring stability of signal transmission.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a corrosion-resistant communication cable, includes the cable core, the cable core comprises cross strip, glass fiber and 1 to 4 twisted pairs, and the twisted pair is located the interlayer of cross strip respectively, the twisted pair is twisted by two wire pairs and is formed, the structure of wire is: the innermost layer is the copper core, the copper core is equipped with the polytetrafluoroethylene layer outward, the polytetrafluoroethylene layer is equipped with the aluminium foil layer outward, and glass fiber fills between paired line and cross, the cable core is equipped with outward and gathers perfluor ethylene propylene thin layer, it is equipped with the ceramic fibre cloth layer outward to gather perfluor ethylene propylene thin layer, the ceramic fibre cloth layer is equipped with the copper wire weaving layer outward, the copper wire weaving layer is equipped with the polyurethane restrictive coating outward.
Preferably, the cross-shaped strip is in a structure that the innermost layer is a high-strength cross nylon strip, and an ethylene propylene rubber layer is wrapped outside the high-strength cross nylon strip.
Preferably, the material of the copper core is single crystal copper.
The single crystal copper has excellent electricity and signal transmission performance, good plastic processing performance, excellent corrosion resistance and obvious fatigue resistance due to elimination of crystal boundary serving as a resistance generation source and a signal attenuation source, is an excellent wire core material, the polytetrafluoroethylene insulating layer has excellent corrosion resistance, the aluminum foil on the surface of the wire plays a role in shielding and preventing mutual interference among wires, the compact oxide layer on the surface of the aluminum foil also has a corrosion resistance function, the cross strip plays a role in isolating and preventing mutual interference among twisted pairs, meanwhile, the high-strength cross nylon strip inside the cross strip also has a function of improving the tensile strength of the cable core, the glass fiber is a fiber with good insulation property, strong heat resistance, good corrosion resistance and high mechanical strength, plays a role in increasing the strength of the cable core and filling and fixing the twisted pairs, and the polyfluorinated ethylene propylene film layer has a function of preventing water vapor invasion, it also has fabulous corrosion resistance to gather the ethylene propylene thin layer self, and ceramic fiber weight is light, high temperature resistant, the heat stability is good, the heat conductivity is low and intensity is high, can strengthen cable bulk strength, can also prevent the burr scratch inside material of copper wire weaving layer, and the copper wire weaving layer plays isolated external interference signal's effect, and the polyurethane restrictive coating has fabulous wear-resisting corrosion resisting property, can effectual protection inside material.
The invention has the beneficial effects that: the communication cable with excellent corrosion resistance is obtained by scientifically combining the properties of different materials, is durable and ensures the stability of signal transmission.
