Embodiment Construction

[0010] Such as figure 1 As shown, the present invention is realized by adopting the following technical solutions: a multi-core coaxial cable, which is composed of a coaxial core 1, a tape layer 3, a galvanized aluminum alloy wire shielding layer 4, and a waterproof layer 6. .

[0011] Wherein, the coaxial core 1 is composed of an inner conductor, an inner skin layer, and an outer conductor of a bare copper wire that are sequentially wrapped;

[0012] The tape layer 3 of the present invention is wrapped with four reinforcing members 2 inside, and the reinforcing members 2 are circumscribed to the adjacent coaxial core 1;

[0013] The galvanized aluminum alloy wire shielding layer 4 of the present invention is provided with a double-layer water barrier layer 5 between the waterproof layer 6;

[0014] The galvanized aluminum alloy wire shielding layer 4 of the present invention is braided by steel-clad steel wires with a braiding density of 45%.

[0015] As a preferred solution of the p...

Abstract

The invention discloses a multi-core coaxial cable. The multi-core coaxial cable comprises a coaxial cable core, a belting layer, a zinc plated aluminium alloy wire shielding layer and a waterproof layer; the coaxial cable core is formed by an inner conductor, an inner skin layer and a bare copper wire outer conductor which are packaged sequentially; four reinforcement elements are packaged in the belting layer; the reinforcement elements and adjacent coaxial cable core are externally tangent; two water-resisting layers are arranged between the zinc plated aluminium alloy wire shielding layer and the waterproof layer; the zinc plated aluminium alloy wire shielding layer is formed by ladle steel wires by knitting with the knitting tightness of 45%. The cable has good conductivity, excellent waterproof property and high break resistance, high property in resisting interference, is mainly used for the fields of power generation, metallurgy, computer, chemical industry, petroleum and the like; meanwhile, the cable core is firm and is not likely to deviate from the position determined initially.

Description

Technical field [0001] The invention belongs to the field of cables, and particularly relates to a multi-core coaxial cable. Background technique [0002] With the development of power industry, data communication industry, urban rail transit industry, etc., various industries have higher and higher requirements for cables. For example, cables laid underwater or underground are prone to insulation damage, insulation deterioration, mechanical damage, and loose cores due to moisture absorption and external force extrusion. [0003] Only by meeting the requirements can the safe use of cables be better guaranteed. Summary of the invention [0004] In order to overcome the above-mentioned defects of the prior art, the purpose of the present invention is to provide a multi-core coaxial cable with good electrical conductivity, excellent waterproof performance, strong anti-breaking ability, high anti-interference and strong core. [0005] The present invention is realized by adopting the fo...
