Utility model content
Be directed to prior art Problems existing, the purpose of this utility model is to provide a kind of wear-resisting, oil resistant, fire-resistant, rat-and-ant proof and discharge the fire-resistant rat-and-ant proof cable of low smoke, zero halogen of non-toxic gas when breaking out of fire.
An embodiment of the present utility model is to provide the fire-resistant rat-and-ant proof cable of a kind of low smoke, zero halogen, comprises at least one oxygen-free copper core conductor; Each oxygen-free copper core conductor outside has wrapped Mica tape layer and cross-linked polrvinyl chloride insulation successively; At least one oxygen-free copper core conductor outside being provided with Mica tape layer and cross-linked polrvinyl chloride insulation is provided with glass fibre belt lapping layer, LSOH anti-flaming separator, steel wire armor layer and oversheath successively.
Preferably, the material of oversheath is nylon 12.
Preferably, the fire-resistant rat-and-ant proof cable of this low smoke, zero halogen comprises an oxygen-free copper core conductor, and oxygen-free copper core conductor is provided with Mica tape layer, cross-linked polrvinyl chloride insulation, glass fibre belt lapping layer, LSOH anti-flaming separator, steel wire armor layer and oversheath outward successively.
Preferably, the fire-resistant rat-and-ant proof cable of this low smoke, zero halogen comprises three oxygen-free copper core conductors; Three be provided with Mica tape layer and cross-linked polrvinyl chloride insulation oxygen-free copper core conductor and glass fibre belt lapping layer between be also provided with glass cord packed layer.
The fire-resistant rat-and-ant proof cable of low smoke, zero halogen of the present utility model by arranging Mica tape layer, cross-linked polrvinyl chloride insulation, glass fibre belt lapping layer, LSOH anti-flaming separator, steel wire armor layer and nylon outer sheath outside oxygen-free copper conductor, this cable is made to have the performances such as good oil resistant, wear-resisting, cold-resistant, high temperature resistant, fire prevention, rat-and-ant proof, and discharge non-toxic gas when breaking out of fire, be convenient to be laid in the particular surroundingss such as dark humidity, range of application is greatly enhanced.

Fig. 2 is the structural representation of the embodiment 2 of the fire-resistant rat-and-ant proof cable of the application's low smoke, zero halogen.
Wherein, 1, oxygen-free copper conductor; 2, Mica tape layer; 3, cross-linked polrvinyl chloride insulation; 4, glass cord packed layer; 5, glass fibre belt lapping layer; 6, LSOH anti-flaming separator; 7, steel wire armor layer; 8, oversheath.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, so that those skilled in the art understand the utility model.
embodiment 1
See Fig. 1, Figure 1 shows that the structural representation of the embodiment 1 of the fire-resistant rat-and-ant proof cable of low smoke, zero halogen of the present utility model; Comprise an oxygen-free copper conductor 1, this oxygen-free copper conductor 1 is outer is provided with Mica tape layer 2, cross-linked polrvinyl chloride insulation 3, glass fibre belt lapping layer 5, LSOH anti-flaming separator 6, steel wire armor layer 7 and oversheath 8 successively.
Wherein, oxygen-free copper conductor 1 has high electrical conductivity energy and mechanical performance, and cross-linked polrvinyl chloride insulation 2 has compared with high insulating property and mechanical performance and high temperature resistant; Glass fibre belt lapping layer 5 has well fire-retardant and heat-blocking action; LSOH anti-flaming separator 6 has well fire-retardant, heat insulation and insulating effect; Steel wire armor layer 7 can bear larger mechanical stress; Oversheath 8 adopts nylon 12 material, and this material has wear-resisting, oil resistant, cold-resistant, corrosion-resistant, high temperature resistant and its Shao's soft more than D70, and having stronger toughness, is fine Ratproof and termiteproof material.
embodiment 2
See Fig. 2, Figure 2 shows that the structural representation of the embodiment 2 of the fire-resistant rat-and-ant proof cable of low smoke, zero halogen of the present utility model; Comprise three oxygen-free copper conductors 1, each oxygen-free copper conductor 1 is outer is provided with Mica tape layer 2 and cross-linked polrvinyl chloride insulation 3 successively; Three oxygen-free copper conductor 1 outsides being provided with Mica tape layer 2 and cross-linked polrvinyl chloride insulation 3 are provided with glass cord packed layer 4, glass fibre belt lapping layer 5, LSOH anti-flaming separator 6, steel wire armor layer 7 and oversheath 8 successively; The material of oversheath 8 is nylon 12.
In sum, the low smoke, zero halogen that the utility model provides fire-resistant rat-and-ant proof cable compensate for that traditional pvc sheath cable is not corrosion-resistant, not oil resistant, not wear-resisting, not fire-resistant, the not deficiency such as rat-and-ant proof, non-toxic gas is discharged when breaking out of fire, and larger mechanical stress can be born when mounting and installation, be adapted to large distance and lay.
The foregoing is only the embodiment of the application, be not limited to the application, for a person skilled in the art, the application can have various modifications and variations.Within all spirit in the application and principle, any amendment done, equivalent replacement, improvement etc., within the right that all should be included in the application.
