Utility model content

The utility model object overcomes the easily broken problem of core, and proposing provides wear-resisting, oil resistant under site conditions during a kind of plant equipment higher to the requirement of cable indices is run, the ultra-soft green safety cable of cold-resistant, anti-interference, high flexibility, electric performance stablity.

To achieve these goals, the technical solution of the utility model is achieved in that control cables, it is characterized in that, comprises,

One cable outer layer, has a semiconductive sheath, a sheath from the inside to the outside successively; And,

At least one cable inner core, is positioned at this cable outer layer, and this cable inner core has a conductor wire core, an insulating barrier, an insulation screen from the inside to the outside successively.

As the preferred version of cold-resistant, wear-resisting, oil resistant, soft shielding high flexibility control cables, this conductor wire core is stranded obtained by many zinc-plated soft round copper wires.

As the preferred version of cold-resistant, wear-resisting, oil resistant, soft shielding high flexibility control cables, the external diameter of this copper wire is less than conductor the 6th kind of conductor of cable.

As the preferred version of cold-resistant, wear-resisting, oil resistant, soft shielding high flexibility control cables, by playing, the soft mask overlap of semiconductive is wrapped to be formed this insulation screen.

As the preferred version of cold-resistant, wear-resisting, oil resistant, soft shielding high flexibility control cables, this semiconducting protection layer is extruded in outside this cable core by semiconductive material and forms.

As the preferred version of cold-resistant, wear-resisting, oil resistant, soft shielding high flexibility control cables, this insulating barrier extrudes extrusion modling by elastomer cold-resistant insulation material.

As the preferred version of cold-resistant, wear-resisting, oil resistant, soft shielding high flexibility control cables, this oversheath is cold-resistant, wear-resisting by elastomer, oil resisting material is formed.

Compared with prior art, advantage of the present utility model: improve the physical and mechanical properties of cable, conductor employing tinned copper wire increases antiseptic property, to extrude the mode extruding semiconductive sheath, reduce the transfger impedance of screen, anti-jamming effectiveness is remarkable.Sheath adopts special compound elastomer to improve, and cable resists cold in indoor and outdoor, the performance of wear-resisting, oil resistant, reaches the designing requirement of safety cable.

Accompanying drawing explanation

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

Embodiment

Below in conjunction with drawings and Examples, the utility model is elaborated.

Refer to Fig. 1, shown in figure is that cable is extruded on conductor wire core 1 by conductor wire core 1, insulating barrier 2, overlapping wrapped one deck semiconductive shielding layer 3 outside insulating barrier 2, semiconductive sheath 4 fashion of extrusion is extruded in into outside cable core, and cold-resistant, wear-resisting, oil proof sheath 5 is extruded in semiconductive sheath 4 and forms outside.Cable outer layer time interior cable inner core can have one or more.Conductor wire core 1 is drawn by high-purity tinned copper wire and forms, and conductor employing surpasses six class conductors makes it more soft, the compound elastic body insulated village material extrusion modling of insulating barrier.Overlapping wrapped one deck semiconductive material forms insulation and covers layer, extrudes one deck sheath becoming outside cable core with the form of extruding, and outermost extrudes that one deck is cold-resistant, wear-resisting, oil proof sheath overcoat.

The technical solution of the utility model has been come like this, and the conductor wire core 1 of cable is the conductor drawn by high-purity tinned copper wire.Insulating barrier 2 extrudes shaping by elastomer special insulation material, overlapping wrapped one deck semiconductive shielding layer outside insulating barrier, semiconductive sheath fashion of extrusion is extruded in into outside cable core, and outermost extrudes that one deck resists cold, wear-resisting, oil proof sheath plays good protection effect.

Insulation screen 3 of the present utility model is overlapping wrapped at insulating barrier with the semiconductive nylon of high strength, there are excellent stretch-proof performance, Duplication between 15% ~ 20%, owing to adopting nonmagnetic insulation shielding mode, make it shield and there is electrostatic screen effect completely, obvious to the shield effectiveness of electromagnetic induction, adopt nonmetal shielding material to make cable have lightweight, low cost and other advantages simultaneously.Sheath adopts conductive rubber material fashion of extrusion outside material core to extrude, space between core is all shielded glue extruding by sheath fill up, sheath combines closely with core and makes cable physical structure performance more stable, improves the overall stretching resistance of cable.Adopt different to have two of function of shielding kinds of shielding materials to make for low frequency and high frequency because insulation shielding and sheath shield, sheath shielding is combined again closely with insulation shielding, the inside and outside combination shielding of so common formation one, makes shield effectiveness reach best.Cold-resistant, wear-resisting, oil proof sheath overcoat of the present utility model, sheath adopts polyurethane elastomer, resilience is good especially, creep is little, cold resistance is excellent, anti-circumnutating property of low temperature and flexural fatigue resistance good, there is fabulous resistance to wear, its wearing and tearing are minimum in all elastomers comprising rubber.Meanwhile, it also has outstanding ozone resistance.Polyurethane is in the ozone concentration of 3%, and under the extended state of 20%, but its mechanical performance is substantially constant.In addition the intensity of polyurethane is high, and oil resistance is splendid, adapts to the demand in market better.

Above-mentioned involved each material is all current material, and for those skilled in the art know, therefore not to repeat here for the concrete component of its material or structure.

Below only have expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
