Embodiment 1

[0036] figure 1 A specific structure of an armored data cable for desert use in this application is shown. Such as figure 1 As shown, the armored data cable for desert described in this embodiment includes a sheath structure and a cable core. The sheath structure is a cylindrical structure with a hollow cavity inside, and the cable core is arranged in the cavity.

[0037] In this application, in order to make the data cable more adaptable to the harsh environment of the sandy desert, the above-mentioned sheath structure includes a first sheath layer 1, a steel tape armor 2, a second sheath layer 3, Aluminum tape armor 4 and third sheath layer 5 . Among them, the first sheath layer 1, the second sheath layer 3 and the third sheath layer 5 are all made of insulating materials with low dielectric constant, and the thickness is not less than 1.5mm, and the thickness of the steel tape armor 2 is 0.2mm. -0.8mm, the thickness of the aluminum tape armor is 0.2-0.3mm.

Embodiment 2

[0049] figure 2 It shows the specific structure of another armored data cable for desert in this application. Such as figure 2 As shown, on the basis of Embodiment 1, a shielding layer 9 is provided between the sheath structure and the cable core in this embodiment. The shielding layer 9 is made of metal foil, preferably aluminum foil. The metal foil is wound or covered on the outside of the cable core. In order to ensure its shielding effect, it is overlapped at the overlap of the winding or covering. Specifically, in this embodiment, the overlapping rate is greater than or equal to 25%.

[0050] Other structures in this embodiment are consistent with those in Embodiment 1, and have the same technical effect, and will not be repeated here.

Embodiment 3

[0052] This embodiment discloses a method for preparing an armored data cable for deserts, comprising the following steps:

[0053] a) Make twisted pair: prepare the raw material copper rod of conductor 8, wire drawing is carried out to copper rod, then coat insulating material PE outside copper wire, make the outer side of copper wire conductor 8 be wrapped with insulating layer 7; Then, two 8 pairs of conductors with an insulating layer 7 are twisted into twisted pairs;

[0054] b) making the cable core: installing four twisted pairs in the accommodation cavity of the skeleton 6 by a cable forming machine to make the cable core;

[0055] c) Fabrication of the sheath structure: after the third sheath layer 5 is coated on the outer side of the cable core, the aluminum tape armor 4 , the second sheath layer 3 , the steel tape armor 2 and the first sheath layer 1 are arranged in sequence.

[0056] Further, after the step of making the cable core is completed, a layer of shieldi...

Abstract

The invention discloses an armored data cable for desert and a preparation method thereof, and relates to the technical field of data transmission cables. The armored data cable for the desert comprises a sheath structure and a cable core, wherein the sheath structure is cylindrical, and the interior of the sheath structure is provided with a hollow cavity; the sheath structure includes a first sheath layer, a steel tape armor, a second sheath layer, an aluminum tape armor and a third sheath layer; the steel tape armor is arranged on the inner side of the first sheath layer; the second sheathlayer is arranged on the inner side of the steel tape armor; the aluminum tape armor is arranged on the inner side of the second sheath layer; the third sheath layer is arranged on the inner side of the aluminum tape armor; and the cable core is arranged in the cavity. According to the invention, the two layers of armors are arranged in the sheath structure, so that the protection strength of thecable core is enhanced, and the risk of data transmission interruption caused by rat damage is reduced. Meanwhile, the three sheath layers are arranged inside and outside the two armors, and the sheath layers are made of insulating materials with low dielectric constants, so that the external radiation of the steel tape armors and the aluminum tape armors and the internal interference to the cablecore can be reduced.

Description

technical field [0001] The application relates to the field of data transmission cables, in particular to an armored data cable for desert use and a preparation method thereof. Background technique [0002] In the desert environment, the laying and use of data cables are facing great challenges. First of all, most desert areas are dry and windy, and the sand dunes move frequently, which can easily cause the data cables buried under the sand to be exposed on the ground, which is easy to be damaged by people or animals. Secondly, the large temperature difference between day and night in desert areas can easily cause thermal expansion and contraction of the sheath material, resulting in intermittent data transmission. Finally, rodents are active in desert areas, and the outer sheath is often eaten severely, which reduces the protection of the outer sheath on the cable core, and even leads to cable breakage and data transmission interruption. [0003] For example, the Chinese ...
