Description

Special steel wire braided armored cable with fluoroplastic insulating and fluoroplastic sheath

Technical Field

The utility model relates to the technical field of cables, specifically be a sheath special type cable is woven to fluoroplastics insulating sheath steel wire.

Background

The cable is mainly used for transmission of electric power and signals, because the different of cable service environment, the specification requirement to the cable is also different, especially special cable, be used for signal transmission such as transmission line and computer network, subway, vehicle of electrical apparatus instrument and automatic system in some adverse circumstances, must have excellent performance, traditional cable can realize having resistant oil, waterproof, corrosion-resistant, ageing-resistant, characteristics such as incombustible, but the cost is comparatively expensive, and the big quality of cable thickness is heavier, be unfavorable for the installation use, the indirect performance that leads to the cable reduces, for this reason, we propose a fluoroplastic insulation fluoroplastics sheath steel wire and weave armor special cable.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an armor special type cable is woven to fluoroplastics insulating fluoroplastics sheath steel wire to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fluoroplastic insulating fluoroplastic sheath steel wire weaves armor special type cable, includes the soft copper conductor, the crowded package fluoroplastic insulating layer of outer wall of soft copper conductor, the outer wall installation of fluoroplastic insulating layer is around the package area, and packs the fire retardant around the space department between package area and the fluoroplastic insulating layer, the crowded package fluoroplastic inner pad layer of outer wall around the package area, the armor has been woven to the outer wall of fluoroplastic inner pad layer, the crowded package restrictive coating of outer wall of armor, the wear-resisting strip of outer wall evenly mounted of restrictive coating.

Preferably, the soft copper conductors are provided with five groups, and the five groups of soft copper conductors are sequentially circularly arranged on the inner side of the wrapping tape.

Preferably, the armor layer is formed by weaving steel wires which are arranged in a staggered mode, and the thickness of the armor layer is 1 mm.

Preferably, the flame retardant is a magnesium hydroxide flame retardant.

Preferably, the sheath layer is a fluoroplastic sheath, and the wear resistant strips and the sheath layer are of an integrally formed structure.

Compared with the prior art, the beneficial effects of the utility model are that: this armoured special type cable is woven to fluoroplastics insulating fluoroplastics sheath steel wire, through the restrictive coating that sets up, have fire-retardant, the electrical property is excellent, high temperature resistant, the excellent characteristics of mechanochemical properties, can guarantee that this special type cable is applicable to various adverse circumstances, the armor that sets up simultaneously not only can provide sufficient intensity for the cable, can also prevent biting of mouse ant and destroy, prolongs its life, this cable light in weight, the cost is low in addition, and easy to assemble uses.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a soft copper conductor; 2. a fluoroplastic insulating layer; 3. wrapping a tape; 4. filling a flame retardant; 5. a fluoroplastic inner cushion layer; 6. an armor layer; 7. a sheath layer; 8. wear resistant strips.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides an armor special type cable is woven to fluoroplastics insulating fluoroplastics sheath steel wire, including soft copper conductor 1, the crowded package fluoroplastics insulating layer 2 of the outer wall of soft copper conductor 1, be favorable to isolated electric current, prevent that the electric current from leaking, soft copper conductor 1 at first carries out the wire drawing, soften and stranded conductor, form the cable core with fluoroplastics insulating layer 2 insulation extrusion again, the outer wall installation of fluoroplastics insulating layer 2 is around band 3, can increase the compactness of cable, and pack fire retardant 4 around the space department between band 3 and fluoroplastics insulating layer 2, not only can increase the rounding degree of cable, still have flame retardant efficiency, crowded package fluoroplastics inner cushion 5 around the outer wall of band 3, the cable core that can the protection cable, armor 6 has been woven to the outer wall of fluoroplastics inner cushion 5, the crowded package restrictive coating 7 of the outer wall of armor 6, wear-resistant strip 8 of the outer wall.

The soft copper conductors 1 are provided with five groups, and the five groups of soft copper conductors 1 are sequentially and circularly arranged on the inner side of the wrapping tape 3, so that the signal transmission efficiency is improved;

the armor layer 6 is formed by weaving steel wires which are arranged in a staggered mode, the thickness of the armor layer 6 is 1mm, the armor layer 6 can provide enough strength for a cable, and damage caused by biting of rats and ants can be prevented;

the flame retardant 4 is a magnesium hydroxide flame retardant, the magnesium hydroxide is a novel filling type flame retardant, the surface temperature of the cable core in flame is reduced by releasing combined water and absorbing a large amount of latent heat when the magnesium hydroxide is heated and decomposed, the generated combustible gas is cooled, the magnesium oxide generated by decomposition is a good refractory material, the fire resistance can be further improved, and simultaneously, the water vapor emitted by the magnesium hydroxide can also be used as a smoke suppressant;
