Abstract
The utility model discloses a flat telephone wire used for communication. The flat telephone wire used for the communication comprises a first copper wire core and a second copper wire core which are arranged in a parallel mode at intervals. The external surfaces of the first copper wire core and the second copper wire core are covered by an insulation sheath layer and are isolated from each other by the insulation sheath layer. The upper surface and the lower surface of the insulation sheath layer are both provided with wedge-shaped grooves. The wedge-shaped grooves are arranged between the first copper wire core and the second copper wire core. The first copper wire core and the second copper wire core comprise aramid fiber fibers positioned in the centers and six copper wires intertwisted with the surface of each aramid fiber fiber. The outer sides of the first copper wire core and the second copper wire core are respectively provided with second aramid fiber fibers. The second aramid fiber fibers are in linear directions of the first copper wire core and the second copper wire core. According to the flat telephone wire of the utility model, cable laying is provided with great convenience; the tensile strength of the telephone wire is raised; and interferences of signal transmission are simultaneously reduced.
