Abstract
A special type high strength long span aluminum alloy cable is provided. Each wire core is composed of an aluminum alloy conductor and an insulation layer, the insulation layer is arranged outside the aluminum alloy conductor; three wire cores are intertwined together as a triangle, and a liner layer, an interlocking aluminum alloy armor layer and a cover layer are successively arranged outside. The cable has the following advantages, first, the intensity is high, special components are added in pure aluminum and special processing technology is adopted, tensile intensity is greatly enhanced, and elongation percentage is enhanced 30%; second, the weight is light, the weight is only half of copper under the same electrical performance, deadweight with a length of 4 000 meters can be supported by the alloy cable, a copper cable can only support 2750 meters, the alloy cable is more suitable for long span electric energy transmission; third, the price is low, the price is 30-50% lower than that of the copper cable under the same electrical performance; fourth, the intensity is high, the flexibility is good, the external diameter is 10% larger than that of the copper cable under the same electrical performance, the bending radius is only 7 times of the cable diameter, the bending radius of the copper cable is 12 to 20 times of the cable diameter; fifth, the service life is long, the service life of the copper cable is 30 years, the service life f the aluminum alloy cable is 40 years; and sixth, as long span electric energy transmission can be realized, various subsidiary facility costs can be reduced relatively, and installation is more convenient.
Description
Technical field
The utility model relates to the cable technology field, especially a kind of aluminium alloy cable.
Background technology
Along with the development of society, the quickening of various paces of construction, cable is seized of consequence as the artery of country in various construction.Traditional copper core cable is because the copper resource is few, price is high, from great, and aluminium cable is because intensity is low, the factors such as frangibility, can not satisfy the demand of all kinds of construction, particularly in the place of the large leap of some high strength (such as stadiums, river course, super wide road etc.), not only cost is high for common copper core or aluminium cable, useful life is low, and does not also reach specification requirement in the large leap of high strength.
Summary of the invention
The utility model purpose provides the large leap aluminium alloy cable of a kind of high strength.
As preferably, described core is three.
The technical scheme that the utility model adopts is: every core is made of aluminium alloy conductor and insulating barrier, and insulating barrier is located at outside the aluminium alloy conductor; Three triangular in shape twisting together of core are provided with inner covering, chain aluminium alloy armored layer and outer jacket outward successively.
Advantage of the present utility model is mainly reflected in: a intensity is high, adds special composition and adopted special processing technology in fine aluminium, improved greatly the hole tensile strength, and elongation improves 30%; B. lightweight, weight only is half of copper under the equal electric property, and alloy cable can support the deadweight of 4000 meters length, and copper cable can only support 2750 meters, is more suitable for the electric energy transmitting of large span; C. price is low, hangs down 30%～50% than copper cable price under the equal electric property; D. intensity is high, and pliability is good, and lower of equal electric property is larger 10% than the external diameter of copper cable, and bending radius only is 7 times of cable size, and copper cable is 12～20 times; E. long service life, copper cable useful life is 30 years, and aluminium alloy cable is 40 years; F. because electric energy transmitting that can large span, so also relative reduce of various affiliated facility expense is installed also more convenient.
Description of drawings
Accompanying drawing is the utility model cross-sectional view: 1 is aluminium alloy conductor, and 2 is insulating barrier, and 3 is inner covering, and 4 is chain aluminium alloy armored layer, and 5 is outer jacket.
Embodiment
Referring to accompanying drawing, the utility model is to be twisted together by 2, three core of aluminium alloy conductor 1 outer extruded insulation layer, and outer wrapping lining-layer 3 is chain aluminium alloy armored layer 4 outside the inner covering 3, the chain aluminium alloy armored layer 4 outer outer jacket 5 that extrudes.
Claims (1)
1. the large leap aluminium alloy cable of special high-strength, it is characterized in that: every core is made of aluminium alloy conductor and insulating barrier, and insulating barrier is located at outside the aluminium alloy conductor; Three triangular in shape twisting together of core are provided with inner covering, chain aluminium alloy armored layer and outer jacket outward successively.
