Abstract
The utility model discloses an environmental-friendly flame-retardant computer cable for an automatic fire control system, which comprises insulated wire cores; each insulated wire core comprises a halogen-free insulation layer wrapped by a conductor; two or three insulated wire cores are stranded into a wire group; a split screen sleeve is wrapped outside the wire group, and a low-smoke halogen-free flame-retardant oxygen barrier layer is wrapped outside the split screen sleeve to form a split screen sleeve protection layer so as to form wire group units; a low-smoke halogen-free flame-retardant package layer is wrapped outside a plurality of wire group units; low-smoke halogen-free flame-retardant filling ropes are filled between the plurality of the wire group units and the low-smoke halogen-free flame-retardant package layer to form a cable core; and a total screen sleeve is wrapped outside the cable core, the low-smoke halogen-free flame-retardant oxygen barrier layer is wrapped outside the total screen sleeve, and a protective cover is wrapped outside the total screen sleeve protection layer. The environmental-friendly flame-retardant computer cable for the automatic fire control system is characterized by stable signal transmission, strong anti-interference capability, outstanding flame-retardant effect, environment protection and the like, and is particularly applicable to automatic fire control and similar control systems.
Description
Technical field:
The utility model relates generally to a kind of cable, relates in particular to a kind of automatic fire fighting system environmental-protection flame-retardant computer cable.
Technical background:
Along with the high speed development that urbanization is built, high density, modern commerce or household skyscraper are seen everywhere, and impel novel automatic fire fighting control system to be able to extensive utilization.The safe operation of system be unable to do without stable signal transmission, the reliable computer control cable that certain continuous service ability also can be arranged under some emergency case; Traditional computer control cable is intended to conductor, insulation, the examination of sheath performance, not high to the shielding attention degree, do not reach the requirement of novel automatic fire fighting control system, and traditional fire-retardant computer cable use has the halogen material in a large number, though fire resistance is fine, but under the situation of burning, discharge a large amount of halogen acid gas, influence the correct judgement of automation control system, in automatic fire fighting safety system and similar system so traditional computer control cable is not suitable for using.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of defectiveness; a kind of automatic fire fighting system environmental-protection flame-retardant computer cable is provided; adopt low-smoke non-halogen flame-retardant oxygen barrier layer protection structure and by the novel environment friendly, the fire-retardant computer cable that combine from interior three-dimensional fire-retardant solution, to satisfy the requirement of automatic fire fighting control system and similar system outward.
The utility model is achieved through the following technical solutions:
A kind of automatic fire fighting system environmental-protection flame-retardant computer cable; include insulated wire cores; described insulated wire cores is made up of the Halogen insulating barrier of conductor parcel; two of described insulated wire cores together or three be twisted into the line group together; described line group is wrapped with the split screen cover; described split screen cover is wrapped with split screen cover protective layer and constitutes line group unit; described a plurality of line groups unit is wrapped with the low-smoke non-halogen flame-retardant belting layer; be filled with the low-smoke non-halogen flame-retardant gasket for packing between described a plurality of line group unit and the low-smoke non-halogen flame-retardant belting layer and constitute cable core; described cable core is wrapped with total screen cover; described total screen cover is wrapped with the low-smoke non-halogen flame-retardant oxygen barrier layer and forms total screen cover protective layer, and described total screen cover protective layer is wrapped with oversheath.
Described automatic fire fighting system environmental-protection flame-retardant computer cable, it is characterized in that: described oversheath is a low smoke halogen-free flame-retardant polyolefin.
Described split screen cover and total screen cover adopt wrapped respectively or braiding or adopt combining form to wrap up outside online group and the cable core.
It is wrapped that described split screen cover and the wrapped form of total screen cover adopt copper to mould to be with, and type of weave adopts the tinned copper wire braiding, and combining form is the wrapped outer tinned copper wire braiding of internal layer plastic-aluminum band.
The utility model has the advantages that: adopt that shielding oxygen barrier layer protection structure is existing quite significantly to delay to shield the effect that wrecks, improve the fire-retardant index of whole cable system again; All nonmetallic materials such as insulation, filling, band, sheath all are the low smoke and zero halogen materials, do not contain harmful gas, compare with the traditional computer cable, stable signal transmission is arranged, several big characteristics such as antijamming capability is strong, flame retardant effect is outstanding, environmental protection, be specially adapted to automatic fire fighting and similar control system.
Description of drawings:
