Abstract
The invention discloses a light-load high-fall control signal cable. The light-load high-fall control signal cable includes a cable core which is formed by intertwisting seven insulated wire cores by adoption of a ''1+6'' structural form; a belting, a shielding layer and an outer sheath are extruded outside the cable core in sequence; and the insulated wire cores consists of a load-bearing unit formed by stranding high-strength low-specific-gravity carbon fiber filaments by adoption of a ''1+6'' mode, a conductor formed by stranding a plurality of copper-clad aluminium alloys or aluminium magnesium alloys by adoption of a ''1+6'' mode and an insulating layer extruded outside the conductor, and the conductor is stranded outside the load-bearing unit by adoption of a ''1+6'' structural form with the load-bearing unit as the center. According to the light-load high-fall control signal cable provided by the invention, the weight of the cable itself is reduced, and the tensile strength of the cable is greatly improved, thereby fully satisfying using requirements of a place in a high-fall area.
Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of underloading height drop control signal cable.
Background technology
Due to the needs of the particularly high drop area operation on high mountain hills, high drop light-load control signal cable as the product supporting with it, range of application and usage quantity more and more wider.High drop light-load control signal cable be mainly used in field particularly high mountain hills and high drop area operation needs.Because drop is comparatively large, the cable used just is needed to bear and the weight of cable own just should be lighter.
Due to increasing of field work, complicated geographical environment, particularly high drop area, particular/special requirement be it is also proposed to control signal cable supporting with it: cold-resistant, the wear-resisting and function of shielding that usual field control signal cable not only will be had to possess, and require to be applicable to bearing and lightweight feature itself of high drop area.Because general control signal cable does not possess These characteristics, this just requires producer's Gonna breakthrough technology barriers, seeking breakthrough in the construction of cable and cable new material and new technology.
Summary of the invention
In order to overcome the deficiencies in the prior art, provide a kind of underloading height drop control signal cable, with reach have excellent to bear, the object of light-weight characteristics own.
For achieving the above object, the invention provides a kind of underloading height drop control signal cable, comprise cable core, described cable core is adopted by 7 insulated wire cores that " 1+6 " version is stranded to be formed; Band, screen and oversheath is extruded successively outward at cable core; The conductor that bearing unit, some bursts of copper-clad aluminum alloy or almag that described insulated wire cores adopts the mode bundle of " 1+6 " to twist by the low-gravity carbon fiber filament of high strength adopt the mode bundle of " 1+6 " to twist and the insulating barrier be extruded in outside conductor are formed, and described conductor adopts the version of " 1+6 " to be stranded in outside bearing unit centered by bearing unit.
Preferably, described insulating barrier is that expanded polypropylene or polyethylene foamed material are formed.
Preferably, described band is PP band or CPP band.
Preferably, described screen is the screen that copper-clad aluminum alloy, aluminum-magnesium alloy wire, copper-clad aluminum alloy weave with aluminum-magnesium alloy wire mixing respectively, and count is not less than 85%.
Preferably, described oversheath is the polyurethane elastomer material formation of high abrasion tension.
Beneficial effect of the present invention is:
1, conductor of the present invention adopt bundle strand carbon fiber filament and around its stranded multiply copper-clad aluminum alloy or aluminum magnesium alloy conductor, because the tensile strength of carbon fiber filament is even higher than steel wire, so what substantially increase cable bears intensity;
2, the present invention due to the conductor stranded around center carbon fiber filament skein bearing unit be copper-clad aluminum alloy or hydronalium, this material, under the prerequisite not affecting Signal transmissions, significantly reduces the weight of conductor, also mitigates the weight of cable thus;
3, the present invention adopts low specific gravity material due to insulating barrier and sheath, also which reduces the weight of cable;
4, the present invention adopts the woven shield of copper-clad aluminum alloy or aluminum-magnesium alloy wire or copper-clad aluminum alloy and aluminum-magnesium alloy wire mixing, serves good shielding action and lighter in weight;
5, the employing of carbon fiber filament load-bearing material, copper-clad aluminum alloy or aluminum magnesium alloy conductor replace traditional copper conductor and copper mesh screen, insulating barrier adopts Ultra-low Specific repeating transmission alveolitoid material and sheath to adopt, and low-gravity high abrasion is resistance to draws material, alleviate the weight of cable itself on the one hand, what greatly improve cable bears intensity simultaneously, meets place, high drop area completely and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, the invention provides a kind of underloading height drop control signal cable, comprise cable core, described cable core is adopted by 7 insulated wire cores that " 1+6 " version is stranded to be formed; Band 4, screen 5 and oversheath 6 is extruded outward successively at cable core; The conductor 2 that bearing unit 1, some bursts of copper-clad aluminum alloy or almag that described insulated wire cores adopts the mode bundle of " 1+6 " to twist by the low-gravity carbon fiber filament of high strength adopt the mode bundle of " 1+6 " to twist and the insulating barrier 3 be extruded in outside conductor 2 are formed, described conductor 2 adopts the version of " 1+6 " to be stranded in outside bearing unit 1 centered by bearing unit 1, require that the layers of copper of copper cover aluminum should be coated on aluminium alloy core evenly, continuously, its surface should smooth, rounding, the defects such as the pit that do not have, crack, dew aluminium.
The employing of carbon fiber filament load-bearing material, copper-clad aluminum alloy or aluminum magnesium alloy conductor replace traditional copper conductor and copper mesh screen, insulating barrier adopts Ultra-low Specific repeating transmission alveolitoid material and sheath to adopt, and low-gravity high abrasion is resistance to draws material, alleviate the weight of cable itself on the one hand, what greatly improve cable bears intensity simultaneously, meets place, high drop area completely and uses.
The above is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
