A dual-network composite transmission and wear-resistant and easy-to-install cable

Abstract

The invention discloses a double-net composite transmission, wear-resistant and easy-to-install cable which comprises a flame-retardant layer, an upper wear-resistant layer, an accommodating cavity, a single-sided aluminum foil layer, a shield insulation layer, an insulation foaming layer, an aluminum core and an insulation layer. The accommodating cavity is arranged between the upper wear-resistant layer and a lower wear-resistant layer. The center of the accommodating cavity is penetrated by the aluminum core. Both the upper end and the lower end of the insulation foaming layer are connected with the exterior surface of the single-sided aluminum foil layer. The inner part of the shield insulation layer is penetrated by data copper conduction lines. Electric copper conduction lines are arranged between the inner side wall of the accommodating cavity and the outer side of the insulation foaming layer. The cable of the invention has a well designed compact structure. The structure of the wear-resistant layer changes the surface structure of a conventional cable so that the cables do not wind together and that the internal copper conduction lines are not likely to be damaged for rotations. Wear-resistant and easy to install, the cable also cooperates with the external protection layer so that the cable skin does not break. Therefore, the use safety of the cable is increased. In addition, the arrangement of data copper conduction lines and electric copper conduction lines realizes double-net composite transmission and avoids the reduction of electric performances.

[0002] In our existing integrated wiring system, generally four pairs of ordinary digital cables are used for Internet access and data transmission, local telephone cables are used for wiring, telephone and voice transmission, and ordinary coaxial cables are used for network TV and high-definition TV. Watching, etc., when the above cables are wired, they need to be wired in the same pipeline to affect and interfere with each other

And because of the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling at low frequencies becomes more and more prominent, which seriously affects the electrical performance of each cable, resulting in the comprehensive wiring of each cable to the home. Internet access speed, telephone call quality, and definition of high-definition images will all be affected to varying degrees, and since each cable is an independent unit, after years of heating and heating, it is easy to cause the sheath of each cable to interact with each other. Adhesion, etc., will eventually lead to broken skin, even electric leakage, burning, and eventually fire. In addition, most cables are round, easy to rotate, etc., and the installation is not very convenient, easy to fall off, and it is not very convenient to use.
