Abstract
The utility model discloses a composite flame-retardant cable in the field of cables, which comprises a cable core. The cable core includes at least one signal wire core and at least one pair of power wire cores, wherein each signal wire core is a conductor with an insulating layer extruded outside, and each power wire core is formed by stranding two conductors with insulating layers extruded outside. An outer conductor covering the outer surface of the cable core includes a composite aluminum strip layer and a tinned copper wire braided layer, wherein the composite aluminum strip layer is in a lapping structure, and the tinned copper wire braided layer covers the outer surface of the composite aluminum strip layer. An oxygen barrier covers the outer surface of the outer conductor, a sheath layer is arranged outside the oxygen barrier in a covering manner, and filling materials are arranged in peripheral gaps among the signal wire cores and the power wire cores in the outer conductor. The composite flame-retardant cable not only can normally transmit electric energy, but also can transmit control and communication signals, and has high-temperature resistant and flame-retardant functions.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of compound flame retardant cable.
Background technology
Along with the high speed development of economic construction and people's growth in the living standard, traditional cable can not satisfy the demands, and is particularly aspect the comprehensive and feature of environmental protection of cable, more and more higher to the requirement of cable.
The most of applicabilities of traditional cable are more single, and mostly are combustible material.In client's construction, produce multiple inconvenience during installation, because traditional cable is not accomplished the dual-purpose or many usefulness of a line, when installation, tend to cause manpower, waste of time; The solid granule that conventional wire cable produces after burning forms smog, reduces light transmittance, influences people's escape during breaking out of fire; Some material also contains halogen, and the pernicious gas that halogen burning back produces has very strong toxicity, the respiratory system of harm people; And smog and toxic gas are the key factors that hinders rescue and escape, causes casualties in the fire.
The utility model content
The purpose of this utility model is too single in order to solve cable feature of the prior art, and flame retardant effect is poor, and the burning back produces the problem of harmful gas, and a kind of compound flame retardant cable is provided, and makes it adapt to versatility, and good flame retardation effect.
The purpose of this utility model is achieved in that a kind of compound flame retardant cable, comprise cable core, described cable core comprises at least one signal core and at least one pair of power supply core, described signal core is for being extruded with the conductor of insulating barrier outward, described power supply core is two stranded forming of conductor that are extruded with insulating barrier outward, the cable core outer surface coats and is provided with outer conductor, described outer conductor comprises clad aluminum belt and tinned wird braid, described clad aluminum belt is wrapped structure, the tinned wird braid is coated on clad aluminum belt outer surface, the outer surface of outer conductor is coated with oxygen barrier layer, the oxygen barrier layer outsourcing covers and is equipped with restrictive coating, is provided with packing material in signal core and the power supply core circumferential play in the described outer conductor.
In the utility model, the signal core and the power supply core that are provided with make it can adapt to versatility, outer conductor by clad aluminum belt and tinned wird braid composition, make advantages of good shielding performance, the tinned wird braid can make the construction of cable stable, the oxygen barrier layer that the outer surface of outer conductor coats, when fire takes place, make that cable can be high temperature resistant, decompose the shell that the back produces oxygen barrier, play fire retardation, the packing material that is provided with in signal core and the power supply core circumferential play in the described outer conductor makes that the structure of cable is more stable.The utility model can also transmit control, communication signal except energy normal transmission electric energy, have high temperature resistant, fire-retardant function.
As improvement of the present utility model, insulating barrier can adopt polythene material to make, and can guarantee thin thickness, good insulation preformance and compressive resistance height, and the concentricity of described signal core and power supply core is not less than 95%, the outside diameter of cable is reduced, weight saving, production cost reduces.
Little for reaching the cable signal propagation loss, the purpose that characteristic impedance is stable, described power supply core is two stranded forming of conductor that are extruded with insulating barrier outward.
In order to make the shielding properties and the softness of cable all be guaranteed, described tinned wird braid count is not less than 85%.
Be the protective layer of generation oxygen barrier after the feasible classification at high temperature, and can not produce harmful gas, described oxygen barrier layer and restrictive coating all adopt the low smoke and zero halogen material to make.
For making the structure of cable more stable, outward appearance is rounding more, and described packing material is a glass cord, can also play fire prevention, fire-retardant purpose.
