Abstract
The utility model discloses a low-temperature-resisting pulling-resisting wear-resisting special combined soft cable for movable occasions. The core of the cable is formed by twisting an insulated dynamic wire core and an insulated control wire core, an aramid fiber pulling-resisting element is arranged in the gap of the core, a cable covering strip layer and an outer sheath are sequentially arranged outside the core, and the outer sheath is made of thermal-plastic polyurethane. The low-temperature-resisting pulling-resisting wear-resisting special combined soft cable for movable occasions is a dynamic combined cable capable of being dragged, twisted, bent and treated crudely under extreme weather conditions (-60 DEG C) and complex geographic environment.
Description
Technical field:
The utility model relates to a kind of moving field and share the wear-resisting extraordinary combination flexible cable of low temperature resistant tension.
Background technology:
Along with the mankind's continually developing to the area of extremely trembling with fear; People are also more and more wider in the scope of activities of cold district; The large-scale exploration extractive equipment and the use of plant equipment are also more and more; And gather low temperature resistant, mobile, crooked, performance electric wire such as pull, then strong guarantee is provided for equipment running steady in a long-term.Common low temperature resistant cable mostly adopts silicon rubber as restrictive coating at present, because silicon rubber self tear resistance is poor, has determined such cable mainly to be used in low temperature and has fixedly laid occasion, is difficult to directly to be used in low temperature and moves the occasion that pulls.
Summary of the invention:
For overcoming the defective of prior art, power, control combination cable that the purpose of the utility model is to provide a kind of can draw in extreme weather conditions (60 ℃) and complicated geographical environment, twist, bend, handle roughly.
The utility model technical solution problem adopts following technical scheme:
Moving field share the wear-resisting extraordinary combination flexible cable of low temperature resistant tension; Cable conductor is twisted into cable by insulation power core and insulation control core; Be provided with the aramid fiber tensile elements in the cable core gap, cable core sets gradually stranding belting layer and oversheath outward, and said oversheath adopts thermoplastic polyurethane.
The design feature of the utility model also is:
The conductor wire harness of said insulation power core is stranded by copper conductor and aramid fiber tensile elements, and the conductor wire harness is provided with outward successively isolates belting layer and ethylene propylene diene rubber insulating barrier.
The conductor wire harness of said insulation control core is stranded by copper conductor and aramid fiber tensile elements, and the conductor wire harness is provided with ethylene propylene diene rubber insulating barrier and thermoplastic polyurethane restrictive coating outward successively.
The copper conductor nominal cross of said insulation power core is at 2mm
2～70mm
2Between, power core core number is 2 core to 4 cores; The copper conductor nominal cross 1mm of said insulation control core
2～10mm
2Between, control core core number is 2 core to 5 cores.
Compared with present technology, the beneficial effect of the utility model is embodied in:
Adopt 6 types of soft copper conductors to add the aramid fiber structure when conductor strand bundle of the utility model is stranded, place an aramid fiber in cable core central authorities during stranding and do tensile elements, restrictive coating and oversheath adopt the thermoplastic polyurethane material to process; It has lower temperature resistance (60 ℃); High strength, resistance to wear, characteristics such as weatherability; This cable can coiling, folding and unfolding, storage under exceedingly odious weather conditions; Also can drag in rock area, mine or in the severe cold tundra, draw, can also be applied in the occasion that is twisted, bends, handles roughly, this cable has the extremely wide scope of application.
Description of drawings:
Fig. 1 is the sectional structure chart of the utility model cable.
Label among the figure: 1 aramid fiber tensile elements, 2 power cores, 3 copper conductors, 4 isolate belting layer, 5 ethylene propylene diene rubber insulating barriers, 6 control cores, 7 restrictive coatings, 8 stranding belting layers, 9 oversheaths.
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Embodiment:
Embodiment: combine Fig. 1; The extraordinary power of present embodiment, control combination flexible cable; Suitable moving field share and low temperature resistant tension wear-resisting, cable conductor is provided with aramid fiber tensile elements 1 by insulation power core 2 and insulation control core 6 stranded strandings in the cable core gap; Cable core sets gradually stranding belting layer 8 and oversheath 9 outward, and cable jacket 9 adopts thermoplastic polyurethane.It can low temperature resistant (60 ℃), high strength, wear-resisting, and oil resistance is excellent.
In specifically being provided with, the conductor wire harness of insulation power core 2 is stranded by copper conductor 3 and aramid fiber tensile elements 1, and the conductor wire harness is provided with outward successively isolates belting layer 4 and ethylene propylene diene rubber insulating barrier 5.The conductor wire harness of insulation control core 6 is stranded by copper conductor 3 and aramid fiber tensile elements 1, and the conductor wire harness is provided with ethylene propylene diene rubber insulating barrier 5 and thermoplastic polyurethane restrictive coating 7 outward successively.The copper conductor nominal cross of insulation power core is at 2mm
2～70mm
2Between, power core core number is 2 core to 4 cores; The copper conductor nominal cross 1mm of said insulation control core
2～10mm
2Between, control core core number is 2 core to 5 cores.Insulation power core and insulation add aramid fiber when controlling core composition cable and do tensile elements in the middle of cable core, its tensile strength is 5-8 times of the steel wire rope of size on an equal basis, and own soft, can guarantee that like this cable bears enough anti-radial pull and flexibility.Insulating barrier adopts ethylene propylene diene rubber to guarantee that cable has good electric property.During the cable stranding tensile elements is placed on cable core central authorities, cable possesses the pulling force that bears in the cable use, the effect of when stranding belting layer 8 plays stranding cable core being tightened behind the assurance finished product; Restrictive coating 7 adopts thermoplastic polyurethane (TPU) with oversheath 9, and its good resistance to low temperature (60 ℃), higher draw tensile strength, the extremely low tabel coefficient of waste have guaranteed that cable moves the life-span that pulls under the environment for use at low temperature.
