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 wires and cables, more specifically to a helical armored cable and a production method thereof. Background technique

[0002] With the development of information today, cables are used as a medium for transmitting information, and the performance of cables is crucial to the transmission of information. In some special occasions, ordinary cables cannot meet the requirements, and some cables with specific functions are required. So there are some special materials 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 strips, steel strips, steel wires, aluminum, aluminum tubes, etc., while steel strips and steel wire braids have high magnetic permeability and good electromagnetic shielding effect, and can be used for low-frequency interference. Materials such as aluminum and copper are resistant to Strong co...
