Abstract
A low-smoke halogen-free high-flame-retardant seven-class wire comprises a wire core, wherein four groups of twisted pairs are uniformly distributed on the outer side of the wire core, an inner shielding layer wraps the outer side of each group of twisted pairs, outer shielding layers are arranged on the outer sides of the four groups of twisted pairs, and the outer shielding layers tightly comprise the twisted pairs; and flame-retardant layers are arranged on two sides of the outer shielding layer, and the outermost side of the outer shielding layer is wrapped with a sheath. Compared with the prior art, the low-smoke halogen-free high-flame-retardant seven-class wire has the advantages that the flame-retardant layer is arranged on the inner side and the outer side of the outer shielding layer, so that the manufacturing is convenient, and the flame retardant property of the mesh wire is improved.
Description
Technical Field
The utility model relates to the technical field of network cables, in particular to a low-smoke halogen-free high-flame-retardant seven-class cable.
Background
The net twine is a data transmission cable, is indispensable in LAN's connection, uses very extensively, and the surface of current seven kinds of net twines has adopted low smoke and zero halogen material, but the inside fire behaviour of net twine still does not reach standard, when meetting the condition of a fire, the net twine is inside still to be burnt easily, so need improve the net twine inside.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a low-smoke halogen-free high-flame-retardant seven-class wire aiming at the defects of the prior art.
In order to solve the technical problems, the utility model adopts the technical scheme that:
a low-smoke halogen-free high-flame-retardant seven-class wire comprises a wire core, wherein four groups of twisted pairs are uniformly distributed on the outer side of the wire core, an inner shielding layer wraps the outer side of each group of twisted pairs, outer shielding layers are arranged on the outer sides of the four groups of twisted pairs, and the outer shielding layers tightly comprise the twisted pairs; and flame-retardant layers are arranged on two sides of the outer shielding layer, and the outermost side of the outer shielding layer is wrapped with a sheath.
Furthermore, the outer shielding layer is formed by weaving shielding wires, the woven outer shielding layer is soaked in a flame-retardant solvent to form a flame-retardant layer, and gaps of the woven shielding wires are filled with the flame-retardant solvent.
Further, the thickness of the flame-retardant layer is 1-1.2 mm.
Further, the inner shielding layer is an aluminum foil.
Furthermore, the sheath adopts low smoke and zero halogen material, and the sheath is inside to be provided with the rope of tearing.
Compared with the prior art, the low-smoke halogen-free high-flame-retardant seven-class wire has the advantages that the flame-retardant layer is arranged on the inner side and the outer side of the outer shielding layer, so that the manufacturing is convenient, and the flame retardant property of the mesh wire is improved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
the cable comprises a cable core 1, a cable core 2, a twisted pair, an inner shielding layer 3, an outer shielding layer 4, a flame-retardant layer 5, a sheath 6 and a tearing rope 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
As shown in fig. 1, a seven-class low-smoke halogen-free high-flame-retardant wire includes a wire core 1, the wire core 1 is made of steel wire, four twisted pairs 2 are uniformly distributed on the outer side of the wire core 1, each twisted pair 2 is formed by mutually winding two copper wires with insulating layers wrapped on the outer sides, an inner shielding layer 3 is wrapped on the outer side of each twisted pair 2, the inner shielding layer 3 is aluminum foil, and outer shielding layers 4 are arranged on the outer sides of the four twisted pairs, because the wire core 1 is arranged, the wire core 1 plays a supporting role on one hand, and on the other hand, the outer shielding layer 4 can tightly include the twisted pair 2, so that the inner hollow is avoided, and the compressive capacity of the wire is improved; the two sides of the outer shielding layer 4 are both provided with flame retardant layers 5, in the embodiment, the outer shielding layer 4 is formed by weaving shielding wires, the woven outer shielding layer 5 is soaked in a flame retardant solvent to form the flame retardant layer, and gaps of the weaving of the shielding wires are filled with the flame retardant solvent.
The thickness of the flame-retardant layer is 1-1.2 mm.
The outside parcel of outer shielding layer 4 has sheath 6, and sheath 6 adopts low smoke and zero halogen material, and 6 insides of sheath are provided with tear rope 7, tear rope 7 and are convenient for tear sheath 6 open.
The present invention is not limited to the embodiments described above, and those skilled in the art may make modifications or changes within the scope of the disclosure without departing from the spirit of the present invention, so that the scope of the present invention is defined by the appended claims.
