Abstract
The invention discloses a high-tensile multi-core rubber sleeve cable which comprises a cable core, wherein gaps in the cable core are filled with fillers, non-woven fabric, an inner sheath and a shielding layer are wrapped around the cable core in sequence, an outer sheath is arranged on the outermost layer of the cable core in a pressing wrapped mode, the cable core is formed by intertwisting of three insulating cable core bodies and three reinforcing cores, each insulating cable core body is formed by combination of a conductor, a conductor shielding layer, an insulating layer, an insulation shielding layer and an armor layer, and the outer side of the conductor is coated with the conductor shielding layer, the insulating layer, the insulation shielding layer and the armor layer in sequence. The high-tensile multi-core rubber sleeve cable has the advantages of being high in flexibility, high in tensile performance, good in bending property, long in service life and the like.
Description
Technical field
The present invention relates to the power cable field, the rubber cover multicore cable that particularly a kind of flexibility is better, resistance to tension is stronger.
Background technology
Now, generally adopt two kinds of methods to improve the tensile property of cable both at home and abroad, a kind of is to increase the tensile property that soft steel core (or steel wire rope) improves whole strand of copper wire in the copper conductor of Plastic-sheathed Cable, another kind is to increase the resistance to tension that the tension silk improves whole strand of cable core in the middle of the cable insulation core, the opposing pulling force is to the mechanism of copper conductor in the time of can satisfying like this Plastic-sheathed Cable and be moved in actual use bending, make not fracture of copper conductor, prolong the useful life of Plastic-sheathed Cable.
According to long-term actual operating position, through market survey, behind dissection, the above two kinds of tensile type Plastic-sheathed Cables of analysis, can find that all there is very large shortcoming in two types Plastic-sheathed Cable: when increasing stone dead wire (or steel wire rope) in the copper conductor, at the stressed stone dead wire (or steel wire rope) that makes of cable when occuring bending and deformation, easily to copper wire conductor pinch, make it distortion even fracture; When increasing the reinforcing element of pulling force silk or steel wire composition in the insulated wire cores, when pulling force silk or reinforcing element are occured bending and deformation, easily to the insulated wire cores outer jacket, screens etc. cause friction or extruding, because the location comparison of pulling force silk and reinforcing element is fixed, through after the long period, the outer jacket of insulated wire cores and screen will be damaged even be worn out, both of these case all can affect the normal operation of cable, interrupt transmission of electricity when serious, cause fault or the accidents such as short circuit breaking out of fire, the desired value that should produce effect and use this class Plastic-sheathed Cable when therefore failing to reach design, even under the impact of some force majeure that causes of some occasion or natural calamity, this type of old cable is also shorter than the general common Plastic-sheathed Cable life-span on the contrary.
Summary of the invention
The technical problem to be solved in the present invention provides the rubber cover multicore cable of a kind of high flexibility, high tensile ability, good bending property, long service life.
A kind of high tensile rubber cover multicore cable of the present invention comprises cable core, and the gap in cable core is provided with filling, successively wrapped nonwoven fabrics, inner sheath, screen outside cable core, and outermost layer extrudes oversheath; Cable core is to thoroughly do away with edge core and three stranded forming of strengthening core by three, and described insulated wire cores is by conductor and is coated on successively conductor outer conductor shield, insulating barrier, insulation screen, armour and combines.
Further improve, described screen adopts the metal armouring structure to consist of.
Further improve, described armour is made of stainless steel band.
Further improve, described strengthening core is to form by the multiply finer wire is stranded again.
Beneficial effect of the present invention is:
The present invention is by arranging three strengthening cores simultaneously stranded with insulated wire cores in cable core, not only can strengthen greatly tensile property and the bending property of cable, each section that makes cable conductor is in the face of pulling force radially and longitudinally the time, strengthening core can both replace cable conductor and core bearing tension, extruding force and expansionary force etc., and have more flexibility, can adapt to flexibly and resist cable rises owing to own wt causes on the two ends, middle sinking, or the mechanical tension of a certain position of cable when being subject to two ends and stretching, make the stretching resistance performance of cable higher, stronger.
Description of drawings
Fig. 1 is structural representation of the present invention;
Embodiment:
As shown in Figure 1, a kind of high tensile rubber cover multicore cable of the present invention comprises cable core, it is characterized in that: the gap in cable core is provided with fills 6, successively wrapped nonwoven fabrics 7, inner sheath 8, screen 9 outside cable core, and outermost layer extrudes oversheath 10; Cable core is to thoroughly do away with edge core and three strengthening core 11 stranded forming by three, and described insulated wire cores is by conductor 1 and is coated on successively conductor 1 outer conductor shield 2, insulating barrier 3, insulation screen 4, armour 5 and combines.
Screen 9 described above adopts the metal armouring structure to consist of; Described armour 5 is made of stainless steel band; Described strengthening core 11 is to form by the multiply finer wire is stranded.
The invention provides a kind of high tensile rubber cover multi-core cable structure form and implementation method; the above only is preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
