Problems solved by technology

Because the inside of the cable is closed, the heat is not easy to dissipate, which will eventually lead to an increase in the resistance of the electrical transmission unit, a larger transmission loss, and a greater impact on the attenuation of the optical transmission unit.

Abstract

The invention discloses a photoelectric hybrid transmission heat balance cable and a preparation method thereof. The method comprises the steps that strands of silver-coated copper-clad aluminum tows are bunched into a bunch and shape-pressed into a fan-shaped structure; b a fluorine plastic extrusion device is used to extrude a layer of fusible polytetrafluoroethylene on the surface of a fan-shaped bunched conductor; c thermal conductive nylon is extruded and shaped on a nylon extrusion device by a fan-shaped mold; d a tight-cover extrusion device is used to extrude a layer of nylon on the surface of a colored single-mode optical fiber; e a sheath extrusion device is used to extrude a thermoplastic elastomer light-unit sheath on the surface of bunched tightly-bound nylon optical fiber and Kevlar aramid yarns; f a cage type cable forming machine is used to twist an optical transmission unit, an electric transmission unit, a heat balance unit and a reinforcing member into a cable; and g a plastic extrusion device is used to extrude a thermoplastic elastomer on the surface of a cable core wrapped by a wrapping layer. According to the invention, heat in the cable is continuously and stably transmitted out to ensure the photoelectric transmission stability of the cable and the safety of the cable.

Description

technical field [0001] The invention relates to a high-current photoelectric hybrid cable, in particular to a photoelectric hybrid transmission heat balance cable. Background technique [0002] Ordinary high-current optical-electrical hybrid transmission cables generally simply synthesize the optical transmission unit directly. Most of the cables have irregular shapes and structures. The cables are large in size and heavy in weight, which makes them clumsy and unfavorable for laying. At the same time, after a large current passes through the cable for a long time, a large amount of heat will be generated inside the cable. Since the inside of the cable is closed, the heat is not easy to dissipate, which will eventually lead to an increase in the resistance of the electrical transmission unit, a larger transmission loss, and a greater impact on the attenuation of the optical transmission unit. Contents of the invention [0003] The object of the present invention is to solv...
