Abstract
The utility model discloses a low-smoke halogen-free environment-friendly control cable, including a center conductor, a plurality of inner conductors, and a plurality of outer conductors. The center conductor, the plurality of inner conductors and the plurality of outer conductors are externally and respectively provided with cross-linked polyethylene insulation layers to form a center insulation wire core, a plurality of inner insulation wire cores and a plurality of outer insulation wire cores. The plurality of inner insulation wire cores are uniformly distributed outside the center insulation wire core. The outside of the plurality of inner insulation wire cores is provided with an inner wrapping layer. The plurality of outer insulation wire cores are uniformly distributed outside the inner wrapping layer. The outside of the plurality of outer insulation wire cores is provided with an outer wrapping layer to form a cable core. The outside of the cable core is provided with a copper wire braiding shield layer and a low-smoke halogen-free polyolefin sheath layer. The low smoke halogen-free environment-friendly control cable is reasonably designed, uses the structure of the inner wrapping layer between the plurality of inner conductors and the plurality of outer conductors and the outer wrapping layer covered outside the plurality of outer conductors, significantly improves the structure compactness and the fire-proof performance of the cable, and satisfies the actual using environment.
Description
Technical field:
The utility model relates to control cables, relates in particular to a kind of low-smoke halogen-free environment control cables.
Background technology:
Along with expanding economy, all trades and professions have different requirements to the performance of cable.Especially to using the cable product performance in adverse circumstances that specific requirement is more arranged, such as the cable that wind power plant uses, require that cable is low temperature resistant, anti-torsion; The cable that metallurgy industry uses requires that cable is high temperature resistant, corrosion resistance; The cable that chemical industry is used requires that cable is acidproof, oil resistant, corrosion resistance.
For previous control cables, structural compactness and fire resistance are relatively poor, how so that the two is taken into account, are problem demanding prompt solutions so that cable satisfies the practical service environment demand fully.
The utility model content:
The purpose of this utility model provides a kind of low-smoke halogen-free environment control cables, and structural compactness and fire resistance are good, satisfies fully in the fire-resistant environment of having relatively high expectations and uses.
The technical solution of the utility model is as follows:
The low-smoke halogen-free environment control cables, comprise center conductor, several inner wires, several outer conductors, it is characterized in that: described center conductor, several inner wires, several outer conductors are provided with respectively crosslinked polyetylene insulated layer outward and consist of the central insulation core, several interior insulated wire cores, several external insulation cores, described central insulation core is outer evenly to distribute by several interior insulated wire cores, several interior insulated wire cores are provided with interior lapping layer outward, interior lapping layer is outer evenly to distribute by several external insulation cores, several external insulation cores are provided with outer lapping layer outward and consist of cable core, and cable core is provided with the proof copper-wire braided screen outward, the low-smoke halogen-free polyolefin restrictive coating.
Described low-smoke halogen-free environment control cables is characterized in that: described interior lapping layer adopts the overlapping wrapped formation of high temperature resistance polyester band.
Described low-smoke halogen-free environment control cables is characterized in that: described outer lapping layer adopts the overlapping wrapped formation of synthetic mica tape.
The utility model has the advantages that:
The utility model reasonable in design adopts to reach the structure that the outside coats interior lapping layer, outer lapping layer between several inner wires, the several outer conductor, so that the structural compactness of cable and fire resistance are obviously promoted, satisfies the environment for use of reality.
