Abstract

The utility model discloses a torsion resistant cable which comprises a cable core, a filling layer, warping belts, an internal protecting sleeve, a metal shielding and an external protecting sleeve, wherein the cable core is formed by twisting four insulated wire cores into a whole, each insulated wire core comprises a conductor and an insulated layer wrapped outside the conductor in an extrusion way and with excellent flexibility and mechanical property, the filling layer is filled in the slice among the insulated wire cores, and external surfaces of the insulated wire cores and the filling layer are wrapped by no-halogen flam-resistant warping belts. A no-halogen flame-resistant internal protecting sleeve is wrapped on the external surfaces of the wrapping g belts and covered with the metal shielding, and a no-halogen flame-resistant external protecting sleeve is wrapped on the external surface of the metal shielding. The utility model has excellent flexibility and torsion resistance, and can not damage the conductor under the condition of the continuous torsion of the cable to guarantee the normal running.

Description

The anti-cable of turning round

Technical field:

The utility model relates to a kind of cable technology, and particularly a kind of have a very big anti-cable of turning round performance.

Background technology:

In recent years, because the continuous development of mining industry is for the consideration to safety, more and more higher to the auxiliary equipment requirement of whole mining usefulness.Cable utilization rate and importance therein is high especially, and it has carried the transmission of whole engineering electricity and the transmission of signal.Owing in the factory of ore deposit, use, cable generally all be exposed to airborne, it is influenced by external force is very serious, often need move, in the process that moves, can be twisted unavoidably, regular distortion can cause the damage of cable inner conductor, and this will cause interruptions in transmissions, is easy to cause serious production accident.

The cable that uses generally is made of conductor, insulation, shielding, sheath etc. now, and it is very weak in the anti-performance of turning round, and useful life is short, and in use, needs overhauling of timing, and so not only waste of manpower increases cost, also has very big potential safety hazard simultaneously.

The utility model content:

The utility model is at the existing various drawbacks of above-mentioned existing cable, and a kind of cable with good flexibility and resistance to torsion is provided.

In order to achieve the above object, the utility model adopts following technical scheme to realize:

The anti-cable of turning round, this cable is made up of cable core, packed layer, band, inner sheath, armouring and oversheath; Described cable core thoroughly does away with stranded the forming of edge cores by four, and insulated wire cores is by conductor and be extruded in the insulating barrier that conductor has good flexibility and mechanical performance outward and form, and fill by packed layer in the space between insulated wire cores; On the outer surface of insulated wire cores and packed layer, coat with the halogen-free flameproof band; Extrude one deck halogen-free flameproof inner sheath on the band outer surface, this inner sheath covers one deck armouring outward, and extrudes one deck halogen-free flameproof oversheath on the outer surface of this armouring.

Described conductor adopts the production technology of SZ strand to make, and not only flexibility is good, and under the situation that cable constantly reverses, can not destroy conductor, guarantees normally operation.Then cable is in operation and reverses (within the specific limits) to any one direction, can not produce destruction to the conductor and the insulation of cable.

Described packed layer is the halogen-free flameproof oxygen barrier layer.

Described armouring is formed by metal wire knitted, and its intensity height, flexibility are good, has guaranteed the tensile property and the softness of cable.

The utlity model has following advantage according to what technique scheme obtained:

(1) cable conductor adopts new production technology, and not only flexibility is good, and under the situation that cable constantly reverses, can not destroy conductor, guarantees normally operation.

(2) cable insulation adopts flexibility good, and the high polymer that mechanical performance is good is guaranteed under the situation of the insulation property that cable is good, makes cable have good flexibility, torsional property.

(3) cable has adopted new cabling process, the constraint of the cabling process of breaking the normal procedure, and cable is in operation and reverses (within the specific limits) to any one direction, can not produce destruction to the conductor and the insulation of cable.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model.

Embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

The cable that the utility model provides has adopted structure as shown in Figure 1 to realize in order to reach the specific (special) requirements of mining usefulness:

This cable is made up of cable core, packed layer, band, inner sheath, armouring and oversheath; Cable core thoroughly does away with stranded the forming of edge core by four, insulated wire cores is by conductor 1 and be extruded in the insulating barrier 2 that conductor has good flexibility and mechanical performance outward and form, conductor adopts the production technology of new SZ strand to make, not only flexibility is good, and under the situation that cable constantly reverses, can not destroy conductor, guarantee normally operation.。Fill by halogen-free flameproof oxygen barrier layer 3 in space between insulated wire cores.

On the outer surface of insulated wire cores and halogen-free flameproof oxygen barrier layer 3, coat with halogen-free flameproof band 4; Extrude one deck halogen-free flameproof inner sheath 5 on band 4 outer surfaces, this inner sheath covers one deck armouring 6 outward, and extrudes one deck halogen-free flameproof oversheath 7 on the outer surface of this armouring.Armouring is formed by the good braided steel wire of flexibility in this structure, and its intensity height, flexibility are good, has guaranteed the tensile property and the softness of cable.

Because the conductor in the cable has adopted new cabling process, the constraint of the cabling process of breaking the normal procedure, cable is in operation and reverses (within the specific limits) to any one direction, can not produce destruction to the conductor and the insulation of cable.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
