Abstract
The invention relates to a fire-resistant and wear-resistant cable comprising a conductor at the center and an insulating layer for covering the periphery of the conductor, wherein the insulating layer comprises a mica tape taped covering, an FRPVC (flame retardant polrvinyl chloride) insulating layer and a nylon protection layer from inside to outside; and a mica tape with stronger fire resistance performance is arranged between the FRPVC insulating layer and the conductor, and the nylon protection layer with the stronger wear resistance performance covers the periphery of the FRPVC insulating layer, thus the whole insulating layer has less possibility of being damaged in the process of using the whole cable, the cable can maintain the normal working in a fire disaster, and the quality of the cable is further improved.
Description
?
Technical field
The present invention relates to a kind of cable.
?
Background technology
Existing cable is made up of at the polyvinyl chloride insulation layer of conductor periphery conductor, extrusion moulding usually, this kind cable in use, thereby its insulating barrier is worn the insulation property of destroying cable easily, has potential safety hazard; Simultaneously, this kind cable is when breaking out of fire, and insulating barrier burns out easily and loses electric conductivity.
?
Summary of the invention
The present invention seeks to a kind of cable with stronger resistance to wear and fire resistance.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of fire-resistant abrasion-proof flame retardant cable, it comprises the conductor that is positioned at the center, the insulating barrier that is coated on described conductor periphery, and described insulating barrier is made up of mica tape lapping layer, flame-proof polyvinyl chloride insulation and nylon sheath successively from nexine to skin.
Further, described conductor is stranded or solid conductor, and diameter is 1.13～3.2mm, and described mica tape lapping layer radial thickness is 0.1～0.3mm, described flame-proof polyvinyl chloride insulating barrier radial thickness is 0.5～0.7mm, and described nylon sheath radial thickness is 0.1～0.3mm.
Described nylon sheath extrusion moulding is in described polyvinyl chloride sheath periphery.
Owing to adopt technique scheme, the present invention has the following advantages: cable of the present invention, by wrapped mica tape between flame-proof polyvinyl chloride insulating barrier and conductor with strong fire resistance, and the nylon sheath that has strong anti-wear performance in the coating of flame-proof polyvinyl chloride insulating barrier periphery, thereby whole cable in use, whole insulating barrier is not easy to sustain damage, mica lapping layer when breaking out of fire outside the conductor makes cable can keep operate as normal, the flame-proof polyvinyl chloride insulating barrier has and prolongs the combustion characteristic preferably, makes the quality of cable be further enhanced.

Wherein: 1, conductor; 2, insulating barrier; 21, mica tape lapping layer; 22, flame-proof polyvinyl chloride insulating barrier; 23, nylon sheath;
Embodiment
Below in conjunction with accompanying drawing, the preferred specific embodiment of the present invention is described:
Cable as shown in Figure 1, it is made up of two parts: conductor 1 and the insulating barrier 2 that is coated on conductor 1 periphery.Wherein, conductor 1 is stranded or the solid copper conductor, and its diameter can be set according to the needs that use, and is generally 1.13～3.2mm.
Described insulating barrier 2 respectively by wrapped mica tape lapping layer 21, extrusion molding in conductor 1 periphery at flame-proof polyvinyl chloride insulating barrier 22 on the mica tape lapping layer 21 and extrusion molding the nylon sheath 23 on flame-proof polyvinyl chloride insulating barrier 22 form.Mica tape has strong fire resistance, and flame-proof polyvinyl chloride insulation fire resistance is good, and nylon is more wear-resisting.By nylon sheath 21 is arranged on outermost layer, the wearing and tearing of insulating barrier in the use have been avoided; By between flame-proof polyvinyl chloride insulating barrier 22 and conductor 1, mica tape lapping layer 21 being set, further played the effect of fire protection flame retarding.
The radial thickness of described mica tape lapping layer 21, flame-proof polyvinyl chloride insulating barrier 22 and nylon sheath 23 also can be adjusted according to the needs of concrete use occasion, usually, the thickness of mica tape lapping layer 21 and nylon sheath 23 is in 0.1～0.3mm scope; The thickness of flame-proof polyvinyl chloride insulating barrier 22 is in 0.5～0.7mm scope.
The present embodiment cable can not damage insulating barrier in installation process, electric wire energy operate as normal during breaking out of fire, and the quality of cable is greatly improved.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
