Thickening sheath can be generally used in structure or increases the structural unit for bearing pulling force, but such structure, also increase cable
Weight so that cable movement is difficult, and operating cost increases.
Utility model content
In view of the above technical problems, the utility model provides a kind of lightweight drag soft rubber cable, reduces the structure of cable
Weight, required pulling force reduces when being moved in so that cable is run, and operating cost reduces.Specifically technical solution is：
A kind of lightweight drag soft rubber cable, including more cores, the core described in every include conductor, are extruded successively outside conductor
Insulating layer, insulation screen, after more core strandings from inside to outside successively wrapped belting layer, extrude the wrapped aramid fiber of sheath, left-hand
Silk, the wrapped aramid fiber yarn of dextrad extrude outer jacket, extrude high abrasion reinforcement sheath.
Further, the conductor uses 5 class annealed copper strand wires, conductor strand lay ratio to be less than 20 times, ensures that cable is curved
Bilge radius is less than 6 times.
Further, it is 0.6 that the insulating layer, which uses POE thermoplastic elastic materials, the insulation shielding thickness,
~1.0mm, insulating layer and insulation shielding double-layer coextrusion, close adhesion is together.
Wherein, the belting layer uses reinforced non-woven fabrics.
Preferably, the sheath is the wear-resisting haloflex extruded, thickness 2.0mm, first insufficient when extruding
Vulcanization, it is in deformable state to make it.
Further, the wrapped aramid fiber yarn of the left-hand is on the sheath of non-full cure, the wrapped aramid fiber of left-hand
Silk is partially embedded into sheath.
For the wrapped aramid fiber yarn of the dextrad outside the wrapped aramid fiber yarn of left-hand, two layers of direction is interlaced on the contrary.
Further, the outer jacket uses wear-resisting haloflex, and with sheath full cure simultaneously, left-hand is wrapped
Aramid fiber yarn is compressed and is embedded in sheath, outer jacket with the wrapped aramid fiber yarn of dextrad, and the wear-resisting entirety of tension resistance is become.Outside
Covering thickness is 3.0 ~ 5.0mm.
Preferably, the high abrasion reinforces sheath to use high-strength polyurethane, thickness being 0.6 ~ 1.0mm.
A kind of lightweight drag soft rubber cable provided by the utility model, cable cover(ing) is divided into two layers, among two layers
First left-hand, rear right are completely bonded together to staggeredly wrapped aramid fiber yarn, ectonexine sheath with intermediate aramid fiber yarn, ensure sheath
The wear-resisting, tension of layer, insulated wire cores are protected in cable in moving process.Insulating layer uses POE thermoplastic elastic materials, has
The characteristic of lightweight, for POE thermoplastic elastomer (TPE)s by ethylene and butylene or Octene Polymerization, density is 0.82 ~ 0.88g/cm3Between, and
With superior insulation performance, heat resistance, cold resistance, weatherability and resistance to ag(e)ing.Insulation material is light, reduces the structure weight of cable
Amount, reduces the operating cost of cable.
Description of the drawings
Fig. 1 is the cross-sectional view of the utility model.
Specific implementation mode
It is described in conjunction with the embodiments specific embodiment of the present utility model.
As shown in Figure 1, a kind of lightweight drag soft rubber cable, including more cores, the core described in every include conductor 1, are led
Extruded insulation layer 2, insulation screen 3 successively outside body 1, after more core strandings from inside to outside successively wrapped belting layer 4, extrude interior shield
Layer 5, the wrapped aramid fiber yarn 7 of dextrad, extrudes outer jacket 8, extrudes high abrasion reinforcement sheath 9 the wrapped aramid fiber yarn 6 of left-hand.
The conductor 1 uses 5 class annealed copper strand wires, conductor strand lay ratio to be less than 20 times, ensures that Cable Bending Radius is small
In 6 times.
The insulating layer 2 uses POE thermoplastic elastic materials, the characteristic with lightweight, POE thermoplastic elastomer (TPE)s by
Ethylene and butylene or Octene Polymerization, density are 0.82 ~ 0.88g/cm3Between, and with excellent insulation performance, heat resistance, resistance to
Cold, weatherability and resistance to ag(e)ing.Insulation material is light, reduces the construction weight of cable, reduces the operating cost of cable.Absolutely
Edge layer thickness is determined according to cable specification.3 thickness of insulation shielding is 0.6~1.0mm, insulating layer 2 and insulation shielding 3 pairs
Layer co-extrusion, close adhesion is together.
The belting layer 4 uses reinforced non-woven fabrics.
The sheath 5 is the wear-resisting haloflex extruded, and thickness 2.0mm, first insufficient vulcanization, makes when extruding
It is in deformable state.
The wrapped aramid fiber yarn 6 of the left-hand on the sheath 5 of non-full cure because sheath 5 also have can
The ability of deformation, the wrapped aramid fiber yarn of left-hand 6 is partially embedded into sheath 5 when wrapped.Aramid fiber yarn is wrapped preceding using doubling winder
Carry out simultaneously silk.
For the wrapped aramid fiber yarn 7 of the dextrad outside the wrapped aramid fiber yarn of left-hand 6, two layers of direction is interlaced on the contrary.Virtue
