Abstract
The utility model relates to the technical field of electrical fittings, and in particular to a steel-cored aluminum strand. The steel-cored aluminum strand includes an inner core and an outer layer; the inner core is steel wire; the outer layer is stranded aluminum conductor; an inerlayer is arranged between the inner core and the outer layer, and is an aluminum cladded steel core wire; and the outer layer is further provided with a protective layer. The steel-cored aluminum strand of the utility model effectively increases the tensile strength of the steel-cored aluminum strand; besides the steel-cored aluminum strand greatly reduces the electric energy loss during transportation of alternating current, due to the conductor skin effect.
Description
Technical field
The utility model relates to the electric armour clamp technical field, specifically is a kind of steel reinforced aluminium conductor.
Background technology
Steel reinforced aluminium conductor is widely used in the overhead transmission line, traditional steel reinforced aluminium conductor is by aluminum steel and steel wire is stranded forms, and inside is steel core, and the outside is to be wrapped in around the steel core by stranded mode with aluminum steel, steel core mainly plays a part to gain in strength, and aluminium stranded conductor mainly works to transmit electric energy.In the prior art, the steel core that has usually adopts single steel wire, and there is the little defective of tensile strength in single steel wire, though have on the basis of single steel wire, increase tensile strength by stranded steel core, but steel wire resistivity height, energy loss is big in the process of electric energy transmission.
The utility model content
At above-mentioned weak point of the prior art, the utility model aims to provide the steel reinforced aluminium conductor that a kind of tensile strength is better, energy loss is littler.
For solving the problems of the technologies described above, steel reinforced aluminium conductor of the present utility model, it comprises that inner core is with outer; described inner core is the steel lead, and described skin is stranded aluminum conductor, is provided with interlayer between described inner core and the skin; described interlayer is aluminium Baogang core lead, also is provided with protective layer on the described skin.
Concrete, the quantity of described aluminium Baogang core lead is 6～12.
The quantity of described aluminium Baogang core lead is 9.
The diameter of described inner core is greater than the diameter of aluminium Baogang core lead.
Described protective layer comprises flame-retardant layer and the watertight composition that arranges from inside to outside.
Steel reinforced aluminium conductor of the present utility model, owing between inner core and skin, interlayer is set, inner core is the steel lead, interlayer is aluminium Baogang core lead, aluminium Baogang core lead has effectively increased the tensile strength of steel reinforced aluminium conductor as interlayer, and in the process of carrying alternating current, owing to exist skin effect, aluminium Baogang core lead that electric energy energy loss in the process of transmission is reduced greatly.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model steel reinforced aluminium conductor.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, steel reinforced aluminium conductor of the present utility model, it comprises inner core 1 and outer 2; described inner core 1 is the steel lead, and described outer 2 is stranded aluminum conductor, is provided with interlayer between the described inner core 1 and outer 2; described interlayer is aluminium Baogang core lead 3, also is provided with protective layer on described outer 2.The utility model is owing to arrange interlayer between inner core 1 and outer 2, inner core 1 is the steel lead, interlayer is aluminium Baogang core lead 3, aluminium Baogang core lead 3 has effectively increased the tensile strength of steel reinforced aluminium conductor as interlayer, and in the process of carrying alternating current, owing to exist skin effect, aluminium Baogang core lead 3 that electric energy energy loss in the process of transmission is reduced greatly.
Concrete, the quantity of described aluminium Baogang core lead 3 is 6～12.In specific embodiment of the utility model, the quantity of described aluminium Baogang core lead 3 is 9.Can effectively increase the tensile strength of steel reinforced aluminium conductor.The utility model also can be according to concrete needs in concrete practice, the aluminium Baogang core lead of quantity reasonable in design.
The diameter of described inner core 1 can be greater than the diameter of aluminium Baogang core lead 3.In the concrete practice, the diameter of inner core 1 can be slightly larger, because there is skin effect in alternating current in the process of transmission, the current density at close conductive surface place is greater than conductor internal current density, so inner core 1 is done the tensile strength that can effectively guarantee steel reinforced aluminium conductor greatly a bit.
Described protective layer comprises flame-retardant layer 4 and the watertight composition 5 that arranges from inside to outside.Watertight composition 5 not only effectively avoid the utility model externally under the environment with the humid air moisture infiltrate its inside, and effectively corrosion-resistant.Flame-retardant layer 4 not only makes the utility model high temperature resistant, and more safe and reliable.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
