Abstract
The utility model discloses a kind of six core double-decker armoured cables, comprise cable core, the center of described cable core is provided with a strengthening core, and strengthening core is provided with some conductors outward; Outside strengthening core and some conductors, extruded insulation layer forms cable core; Waterproofing rope is filled in the gap of cable core, and insulating barrier extrudes the first armour, the second armour outward successively, and outermost layer extrudes oversheath; Its first armour is different from the material that the second armour adopts, and the thickness of its second armour is 2 times of the first armour thickness.Of the present utility model simple in structure, adopt double armor structure, making bending property, tension compressive property, fire resistance, Corrosion Protection is 2 times of original armoured cable, and not be used in and be provided with inner sheath, twining package tape etc., has saved cost; At cable core, stranded place also improves, and makes insulation effect better, has also saved material, has saved cost.
Description
Technical field
The utility model belongs to field of cables, is specifically related to a kind of double-decker armoured cable.
Background technology
In order to prevent from being subject to mechanical damage, power cable, at outer armored protective layer, forms armoured cable.Cable adds that the object of armour is except the mechanical protections such as enhancing tensile strength, compression strength increase the service life; main is to improve cable interference free performance by shielding protection, in addition can be in case pound, press, rack and damage core after cable sheath and cause short circuit.Armoured cable is mainly used in temperature survey, signal transmission and the special heating of chemical industry, metallurgy, machine-building, generating and scientific experimentation etc., and the deficiency of existing armoured cable is: armored protective layer tensile strength is lower, and the external force of bearing is large not; Armored protective layer shield effectiveness is poor, can not be used for the occasion that electromagnetic interference is serious; In addition, cable core is to adopt many stranded the forming of insulated wire cores, and each insulated wire cores outer extruded insulation layer that is conductor, and such to extrude effect bad, in the time extruding, easily ftracture, and waste material.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, lightweight, bending property, tension compressive property, fire resistance, anticorrosive property can better double-decker armoured cable.
A kind of double-decker armoured cable described in the utility model, comprises cable core, and the center of described cable core is provided with a strengthening core, and strengthening core is provided with some conductors outward; Outside strengthening core and some conductors, extruded insulation layer forms cable core; Waterproofing rope is filled in the gap of cable core, and insulating barrier extrudes the first armour, the second armour outward successively, and outermost layer extrudes oversheath; Its first armour is different from the material that the second armour adopts, and the thickness of its second armour is 2 times of the first armour thickness.
Further improve, described conductor is more than 5 or 5, adds aramid fiber tow close and form by steel wire.
Further improve, described insulating barrier adopts polyethylene layer.
Further improve, the first described armour adopts aluminium alloy lock armo layer.
Further improve, the second described armour adopts stainless steel lock armo layer.
Further improve, the thickness of the first described armour is 5-8mm, and the thickness of the second armour is 10-16mm.
The beneficial effects of the utility model are:
Compared with prior art, of the present utility model simple in structure, adopt double armor structure, making bending property, tension compressive property, fire resistance, Corrosion Protection is 2 times of original armoured cable, and not be used in and be provided with inner sheath, twining package tape etc., saved cost; At cable core, stranded place also improves, and makes insulation effect better, has also saved material, has saved cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of double-decker armoured cable described in the utility model, comprises cable core, and the center of described cable core is provided with a strengthening core 1, and strengthening core is provided with some conductors 2 outward; Form cable core at strengthening core 1 and the some outer extruded insulation layers 3 of conductor 2; Waterproofing rope 4 is filled in the gap of cable core, and insulating barrier 3 is outer extrudes the first armour 5, the second armour 6 successively, and outermost layer extrudes oversheath 7; Its first armour 5 is different from the material that the second armour 6 adopts, and the thickness of its second armour 6 is 2 times of the first armour 5 thickness.
Described conductor 2 is more than 5 or 5, adds aramid fiber tow close and form by steel wire; Described insulating barrier adopts polyethylene layer; The first described armour adopts aluminium alloy lock armo layer; The second described armour adopts stainless steel lock armo layer; The thickness of the first described armour is 5-8mm, and the thickness of the second armour is 10-16mm.
The utility model provides a kind of double-decker armoured cable; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection range of the present utility model.
