Abstract
The utility model relates to a twisted steel wire armored protection flexible cable, and belongs to the cable technology field. The technical scheme is that: a PVC elastomer insulating layer (2), a first cable belting (3), a PVC elastomer inner sheath (4), a twisted steel wire armored layer (5), a second cable belting (6) and a PVC elastomer outer sheath (7) are arranged outside a soft copper conductor (1) in order; Flexible copper conductors are extruded by PVC elastomers to form insulation cable cores; the plurality of insulation cable cores form a cabling cable core; the first cable belting wraps the cabling cable core; the the first cable belting is extruded by the PVC elastomer inner sheath; the PVC elastomer inner sheath is wound by the twisted steel wire armored layer; the second cable belting wraps the twisted steel wire armored layer; the second cable belting is extruded by the PVC elastomer outer sheath. The twisted steel wire armored protection flexible cable forms a twisted round steel wire armored element, overcomes the defect of poor flexibility of an original steel wire armored cable and has good tensile and protection performances, and the usage safety of the cable is ensured.
Description
Technical field
The utility model relates to a kind of stranded wire armoring protection flexible cable, belongs to cable technology field.
Background technology
According to the use occasion of cable, cable is divided into and fixedly lays and move and lay, and in the time that cable needs metal armouring protection, need in the construction of cable, increase metal armouring.At present, be generally round steel wire armouring for the metal armouring of cable tensile elements, and this round steel wire armouring tension effect well, but flexibility is bad.Like this, when cable is for mobile occasion, and while needing wire armoring, the inferior position of existing round steel wire armouring has just displayed, on the one hand, the flexibility of round steel wire armouring is bad, has a strong impact on the use of mobile occasion cable, on the other hand, round steel wire is not easy stretching after flexural deformation, can produce extruding to cable inner covering or oversheath, when serious, can be damaged to insulated wire cores, product quality accident occurs.
Utility model content
The utility model object is to provide a kind of stranded wire armoring protection flexible cable, by stranded steel wire armoured mode, provides a kind of flexibility good, and the cable that tensile property is good, solves the problems referred to above that exist in background technology.
The technical solution of the utility model is: a kind of stranded wire armoring protection flexible cable, comprise soft copper conductor, soft copper conductor is provided with the elastic body insulated layer of PVC outward successively, tape for cables one, PVC elastomer sheath, stranded wire armoring layer, tape for cables two and PVC elastomer outer jacket, the elastic body insulated layer of described PVC, that soft copper conductor extrudes PVC elastomer outward, form insulated wire cores, several insulated wire cores form into cable core, become the wrapped tape for cables one in cable core outside, tape for cables one outside extrudes PVC elastomer sheath, PVC elastomer sheath is outer around stranded wire armoring layer, the outer wrapped tape for cables two of stranded wire armoring layer, the outer PVC elastomer outer jacket that extrudes of tape for cables two.
Described stranded wire armoring layer is seven above thin stranded formations of round steel wire, and direction of lay is dextrad, and wrapped stranded wire armoring direction is left-hand.
Described soft copper conductor is 5 classes or the stranded formation of 6 class copper conductor.
The beneficial effects of the utility model are: by adopting the many modes that thin round steel wire is stranded, form stranded round steel wire armouring element, adopt insulation and sheath material that flexible conductor structure and flexibility are good simultaneously, overcome the bad shortcoming of original steel wire armored cable flexibility, stranded round steel wire and single round steel wire ratio simultaneously, there is better tension barrier propterty, ensured the use safety of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: soft copper conductor 1; The elastic body insulated layer 2 of PVC; Tape for cables 1; PVC elastomer sheath 4; Stranded wire armoring layer 5; Tape for cables 26; PVC elastomer outer jacket 7.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of stranded wire armoring protection flexible cable, comprise soft copper conductor 1, the outer elastic body insulated layer 2 of PVC that is provided with successively of soft copper conductor 1, tape for cables 1, PVC elastomer sheath 4, stranded wire armoring layer 5, tape for cables 26 and PVC elastomer outer jacket 7, the elastic body insulated layer 2 of described PVC, it is the outer PVC elastomer that extrudes of soft copper conductor 1, form insulated wire cores, several insulated wire cores form into cable core, become the wrapped tape for cables 1 in cable core outside, tape for cables one 3 outsides extrude PVC elastomer sheath 4, PVC elastomer sheath 4 is outer around stranded wire armoring layer 5, the outer wrapped tape for cables 26 of stranded wire armoring layer 5, the outer PVC elastomer outer jacket 7 that extrudes of tape for cables 26.
Described stranded wire armoring layer 5 is seven above thin stranded formations of round steel wire, and direction of lay is dextrad, and wrapped stranded wire armoring direction is left-hand.
Described soft copper conductor 1 is 5 classes or the stranded formation of 6 class copper conductor.
Stranded steel wire direction of lay is dextrad, and wrapped stranded wire armoring direction is left-hand, has eliminated the stress of stranded steel wire.
Insulating barrier, sheath, outer jacket adopt PVC elastomeric material, and flexibility is good, also can adopt other flexibility material.
