Abstract
The utility model is related to technical field of electric wires and cables, especially a kind of corrosion resistant steel-aluminum wire, including inner core, inner core outer layer has been twisted outer core, inner core aluminium Baogang core is twisted, outer core is stranded in interior core outer surface by aluminium Baogang core and forms, and the thickness of Wai Xin aluminium Baogang core aluminium layer is twice of inner core aluminium Baogang core aluminium layer.A kind of corrosion resistant steel-aluminum wire of the utility model, it is made up of inner core and outer core, the thickness of Wai Xin aluminium Baogang core aluminium layer is set as twice of inner core aluminium Baogang core aluminium layer, it ensure that anticorrosive property whole outside steel-aluminum wire, while the reduction of inner core aluminium layer also reduces production cost.
Description
Technical field
The utility model is related to technical field of electric wires and cables, especially a kind of corrosion resistant steel-aluminum wire.
Background technology
In steel-cored aluminium strand, the coating of steel core surface contacts to form electrochemical corrosion with aluminum steel, because of the current potential ratio of plating
Aluminium is low, and as a result coating is corroded totally quickly, makes steel core exposed to the atmosphere and is corroded.In addition, after coating is corroded totally,
Steel core contacts with aluminum steel and forms electrochemical corrosion, and the current potential of aluminium is lower than iron, and as a result aluminum steel is corroded again.
Utility model content
In order to overcome the shortcomings of the corrosion-resistant intensity difference of existing steel-cored aluminium strand, the utility model provides a kind of corrosion-resistant
Steel-aluminum wire, be made up of inner core and outer core, the thickness of Wai Xin aluminium Baogang core aluminium layer be set as inner core aluminium Baogang core
Twice of aluminium layer.
Technical solution is used by the utility model solves its technical problem：A kind of corrosion resistant aluminium packet steel-core-aluminium twists
Line, including inner core, inner core is twisted by aluminium Baogang core, and interior core outer surface has been twisted outer core by thickening aluminium Baogang core.
Further, include thick aluminium layer and steel core including thickening aluminium Baogang core, aluminium Baogang core includes aluminium layer and steel core.
Further, the thickness including thick aluminium layer is twice of aluminum layer thickness.
The beneficial effects of the utility model are a kind of corrosion resistant steel-aluminum wires of the utility model, due to aluminium
Between each monofilament it is aluminium contact in twisted wire, they are not deposited there is good metallurgical binding between Baogang's core aluminium layer and steel core
Electrochemical corrosion between different metal can greatly slow down the corrosion rate of conducting wire in this way, and the longevity is used so as to extend it
Life, the steel-aluminum wire being made up of inner core and outer core, inner core aluminium Baogang is set as by the thickness of Wai Xin aluminium Baogang core aluminium layer
Twice of core aluminium layer ensure that anticorrosive property whole outside steel-aluminum wire, while the reduction of inner core aluminium layer also reduces
Production cost.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
1. inner core in figure, 2. aluminium Baogang cores, 3. Hou Lv Baogangs cores, 4. outer cores, 5. thick aluminium layers, 6 steel cores, 7. aluminium layers.
Specific embodiment
If Fig. 1 is the structure diagram of the utility model, a kind of corrosion resistant steel-aluminum wire is interior including inner core 1
Core 1 is twisted by aluminium Baogang core 2, and by thickening, aluminium Baogang core 3 is twisted outer core 4 to 1 outer surface of inner core.
Due between aluminium Baogang core aluminium layer and steel core there is good metallurgical binding, between each monofilament be aluminium in twisted wire
Contact, there is no the electrochemical corrosion between different metal for they, can greatly slow down the corrosion rate of conducting wire in this way, so as to
Extend its service life, the steel-aluminum wire being made up of inner core 1 and outer core 4, by the thickness of outer 4 aluminium Baogang core aluminium layer of core
Degree is set as twice of 1 aluminium Baogang core aluminium layer of inner core, ensure that anticorrosive property whole outside steel-aluminum wire, while inner core
The reduction of aluminium layer also reduces production cost, reduces 1 aluminium Baogang core aluminium layer of inner core.
As shown in Figure 1, thickening aluminium Baogang core 3 includes thick aluminium layer 5 and steel core 6, aluminium Baogang core 3 includes aluminium layer 7 and steel
Core 6.The thickness of thick aluminium layer 5 is twice of 7 thickness of aluminium layer.The thickness of outer 4 aluminium Baogang core aluminium layer of core is set as 1 aluminium Baogang core of inner core
Twice of aluminium layer ensure that anticorrosive property whole outside steel-aluminum wire, while the reduction of inner core aluminium layer also reduces
Production cost reduces 1 aluminium Baogang core aluminium layer of inner core.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait
Effect, but fall in the scope of protection of the utility model.
