Problems solved by technology

[0003] However, most of the armored cables currently in production are wrapped with metal materials around the outer circumference of the cable, which is not closed. Although it can protect the cable from some mechanical damage, it cannot solve the problem of premature aging of the cable to a certain extent.

Embodiment Construction

[0046] In order to more fully understand the technical content of the present invention, the technical solutions of the present invention are further introduced and described below with reference to specific embodiments, but are not limited thereto.

[0047] like Figure 1 to Figure 2 As shown, a spiral armored cable includes a cable body 10 and a metal armor layer 20 wrapped around the outer periphery of the cable body 10 . The metal armor layer 20 is provided with an axial joint 21 (that is, when the metal strip is bent, the joints on both sides), and the axial joint 21 is the welding part 22. When the metal strip is bent into a tubular shape, when the welding head 431 is in the shape of a tube. Weld the connection. The welding part 22 is in the form of full welding, and there should be no defects such as pores and cracks, so as to ensure that the metal round tube 25 does not leak. The outer circumference of the metal armor layer 20 is provided with a spiral indentation 23...

Abstract

The invention discloses a spiral armored cable and a production method thereof. The spiral armored cable comprises a cable body and a metal armor layer wrapping the periphery of the cable body, wherein the metal armor layer is provided with an axial joint; the axial joint is a welding part; spiral impressions which extend along the axial direction of the cable body are arranged on the periphery of the metal armor layer; and an inflatable layer for being filled with an inert gas is arranged between the cable body and the metal armor layer. Compared with the prior art, a metal band directly wraps the periphery of the cable body, the axial joint of two sides of the metal band is welded to form a metal round tube, and then the spiral impressions are pressed, so that the spiral armored cable has the advantages that the material is saved, the production technology is simple, the cost is low and the like. The metal armor layer with the spiral impressions has the advantages of good extensibility, high compressive strength, good stability, good flexibility and the like. The inflatable layer between the metal armor layer and the cable body is filled with the inert gas, so that oxidation of the cable is prevented and the lifetime of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of electric wires and cables, and more particularly to a production method of helical armored cables. Background technique [0002] In today's information development, cables are used as a medium for transmitting information, and the performance of cables is very important to the transmission of information. In some special occasions, the general cables cannot meet the requirements, and some cables with specific functions are needed. Therefore, some special materials are wrapped around the cable to improve the performance of the cable. Usually, a layer of metal material is armored around the cable. Commonly used materials are copper tape, steel tape, steel wire, aluminum, aluminum tube, etc., while steel tape and steel wire braid have high magnetic permeability and good electromagnetic shielding effect, which can be used for low-frequency interference, and materials such as aluminum and copper are resistant to Stron...
