Abstract

The utility model discloses a novel armored cable, comprising a cabling insulated wire core where an internal protection layer is formed by extrusion; an armored layer is stranded outside the wire core; a protection layer is formed outside the armored layer by extrusion; wherein, the armored layer is an integrated body which is stranded by profiled single wires; the profiled single wire section can be z-shape, tile-shape, bow-shape, sector-shape or the profiled single wire can be other profiled wires which can lead the steel wires to be stranded into a whole; compared with the prior art, the armored cable is characterized in that the steel wire-typed single wire is armored; the steel wire can bear large pulling force; the profiled single wires can be integrated as a whole to realize the function similar to that of the steel belt so as to resist impact, tensile force and extrusion, and avoid the burst fragments from being inserted in the insulated layer, thus effectively protecting the safety of the cable.

Description

Armoured cable

Technical field

Utility model is about the improvement to armoured cable, relates in particular to a kind of existingly than high-tensile, and very high shock resistance, tension stress, anti-extrusion ability are arranged again, and the armoured cable that processing is simple, cost is low.

Background technology

Cable comprises pulling force laying, usually being subjected to various mechanical external force effects in the process such as use, as the tractive of unwrapping wire when laying, and comes and goes when the tractive of cable own wt, mobile model wireline operation when vertically installing to move and the crooked pulling force that produces etc.; Also comprise extruding force, as transport, lay, collision in the use and the extruding between the cable hank, the pressure of buried cable soil, the pressure of submerged cable water, down-hole, underground cable are because the extruding between machinery, machinery and sleeper, machinery and the columns such as tunnel distortion, landslide, sleeper collapse; Other external force that also comprise some special use occasions in addition, as blasting coal mining, the fragment that detonator and explosion produce thrusts etc.Because the effect of these external force, cable are in use, the easiest being damaged causes stopping production, the person, equipment or bigger accident to take place, and therefore needs metal material to protect cable as armour.Armouring mode commonly used comprises steel-tape armouring, wire armoring etc., but steel-tape armouring can only bear the extruding force effect. can not bear big pulling force; Wire armoring can only bear pulling force, can not bear extruding force again.But in a lot of use occasions, need bear various mechanical external forces simultaneously, these armouring modes all can not satisfy instructions for use.For this reason, Chinese patent 200420062068.4 propose a kind of outside sheath winding steel wire, double-deck different sheathed structures of wrapped steel band outside it again, yet this cable is the processing technology more complicated not only, need through wrapped, different production process, the production equipments of winding twice, production cycle is long and technology is wayward, has also increased material consumption in addition, and cable is on the high side.

Summary of the invention

The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of have simultaneously advantages of higher tensile strength and compression strength are provided, processing easily again, and material consumption is few, the armoured cable that price is low.

For achieving the above object, the utility model provides a kind of new armoured cable, and it comprises the crowded stranding insulated wire cores that sheath is arranged, the outer stranded armour that has of core, and armour is extruded with sheath outward again.And armour wherein is to mesh into an integral body by the type single line to constitute.

Above-mentioned type single line cross section can for Z type, watt shape, arc, fan-shaped or other can make steel wire mesh into all kinds of molded lines of an integral body.These are all same as the prior art.

The described stranding insulated wire cores of this practical core can be power line core, control core, communication core or other cores.Core quantity can be that single core or multicore are stranded, can also be manyly to carry out stranded to core.When the stranding insulated wire cores was single core, armour was non magnetic armour.These are also all same as the prior art.

It is to adopt the type of wire form single line to carry out armouring that the utility model mainly improves; steel wire can bear bigger pulling force; the integral body that can constitute the type single line plays the function of similar and steel band can shock resistance, tension stress, anti-extrusion; and avoid the explosion fragment to insert insulating barrier, effectively protected cable security.

Description below in conjunction with a concrete preferred embodiment further specifies utility model.

Embodiment

Embodiment 1: as shown in Figure 1, armoured cable described in the utility model, middle for squeezing the stranding insulated wire cores 1 that sheath 2 is arranged, core 1 outer stranded have by the type single line mesh into the armour 3 that an integral body constitutes, this type single line cross section is the Z type.

Embodiment 2: as shown in Figure 2, armoured cable described in the utility model, middle for squeezing the stranding insulated wire cores 1 that sheath 2 is arranged, core 1 outer stranded have by the type single line mesh into the armour 3 that an integral body constitutes, this type single line cross section is a watt shape.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
