Abstract
Description
Technical Field
[0001] The utility model relates to the field of cables, in particular to a round conductor cable with high weather resistance. Background Art
[0002] Cables are usually made of several or several groups of wires twisted together into a rope-like cable. Each group of wires is insulated from each other and often twisted around a center wire. The entire outside is covered with a highly insulating covering. The cable has the characteristics of being powered inside and insulated outside.
[0003] Traditional cables are usually made of multiple circular metal wires twisted together. However, the cable core supported by this process will have raised ridges on the surface, which will affect the cable core coating functional layer. Specifically, the raised ridges will cause the coating layer thickness to be uneven. The more the protective layer is cut, the more uneven the thickness will be, which not only affects the cable qualification rate, but also affects the number of functional layers that can be coated. Utility Model Content

[0008] As a preferred technical solution of the utility model, each conductive sublayer includes a plurality of metal wires that can form a circular fan-shaped ring.
[0009] As a preferred technical solution of the utility model, a rust-proof layer is provided on the surface of each metal wire.
[0010] As a preferred technical solution of the present utility model, the material of the metal wire is copper or aluminum alloy.
[0011] As a preferred technical solution of the utility model, the first shielding layer and the second shielding layer are both composed of metal woven mesh and XLPE cross-linked polyethylene, and the first flame retardant layer and the second flame retardant layer are both fireproof cloth.
[0012] As a preferred technical solution of the utility model, the fire-resistant layer is a mica tape, and the armor layer is woven from galvanized L-shaped stainless steel wires.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] A circular conductive sub-layer is formed by multiple fan-shaped metal wires, so that the influence of the protrusions on the surface of the conductive sub-layer on the thickness of the coating functional layer can be reduced; therefore, the influence of the protrusions on the thickness of the coating functional layer is reduced, so more functional layers can be added, thereby improving the overall weather resistance of the cable to meet the needs of more usage environments.

[0021] In this embodiment, the support ribs 1 play a role in supporting and limiting the conductive layer 2 to prevent the cable from spreading out due to the lack of attachment points when weaving. The filling layer 3 protects the conductive layer 2 and can fill the possible gaps in the conductive layer 2 to ensure the smoothness of the surface. The first shielding layer 4 is used to resist electromagnetic interference and shield radiation. The first flame retardant layer 5 and the fire-resistant layer 6 cooperate to enhance the fire resistance and high temperature resistance of the cable.

[0023] In this embodiment, by arranging the second shielding layer 22 and the second flame-retardant layer 23 between every two adjacent conductive sub-layers 21 , the anti-electromagnetic interference and radiation shielding performances as well as the fire resistance performance of the cable can be enhanced.
[0024] Furthermore, each conductive sub-layer 21 includes a plurality of metal wires 211 that can form a circular fan-shaped ring.
[0025] In this embodiment, the circular conductive sub-layer 21 formed by the fan-shaped metal wire 211 can eliminate the protrusions on the surface of the cable core after the transmission twisting, so that the surface of the conductive sub-layer 21 is smoother and more convenient for coating the functional layer.
[0026] Furthermore, a rust-proof layer is provided on the surface of each metal wire 211 .
[0027] In this embodiment, the anti-rust layer can reduce the possibility of the metal wire 211 being rusted.
[0028] Furthermore, the metal wire 211 is made of copper or aluminum alloy.

[0031] The utility model is a highly weather-resistant circular conductor cable, which comprises a circular conductive sub-layer formed by a plurality of fan-shaped metal wires, thereby reducing the influence of protrusions on the surface of the conductive sub-layer on the thickness of the coating functional layer; therefore, the influence of the protrusions on the thickness of the coating functional layer is reduced, so more functional layers can be added, thereby improving the overall weather resistance of the cable to meet the needs of more usage environments.
