Abstract
Disclosed in the utility model is a twisted wire-contained cable. Steel twisted wires are arranged at an inner core of the cable; tin-plated copper twisted wires coat the outsides of the steel twisted wires; and the outsides of the tin-plated copper twisted wires are coated by a rust-proof painting layer. The provided twisted wire-contained cable has the advantages of good extension strength, good anti-corrosion performance, long service life, and high carrying capacity and the like.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of twisted wire cable.
Background technology
At present, overhead stranded conductor is as a class aerial cable of transmission of electric energy, for remarkable contribution has been made in the development of China's electric utility.Along with industrial expansion, the ampacity that common overhead stranded conductor such as steel reinforced aluminium conductor carry is less, transmit larger electric current, certainly will to increase the cross section of aluminium wire, the twisted wire external diameter is corresponding increase also, and cable is subject in air wind resistance also increases, particularly rain freeze, the harsh climate such as ice and snow weather, likely because freezing, cause the interruption of cable line, economy is lost.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of have tensile strength preferably, Corrosion Protection is strong, the life-span is long, ampacity is large twisted wire cable.
A kind of twisted wire cable described in the utility model, this cable inner core is provided with steel strand wire,, at steel strand wire outer cladding tin-coated copper twisted wire, also scribbles rust preventive coating outside the tin-coated copper twisted wire.
Further improve, the quantity of described steel strand wire is 7.
Further improve, the quantity of described tin-coated copper twisted wire is 12 again.
The beneficial effects of the utility model are:
Inner core of the present utility model adopts steel strand wire, and its stretching resistance is larger, and the tin-coated copper twisted wire is adopted in outside, has the large effect of ampacity, the tin layer of tin-coated copper twisted wire can prevent the aerial oxidation of copper, and tin-coated copper twisted wire outside scribbles antirust paint, has etch-proof effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of twisted wire cable described in the utility model, this cable inner core is provided with 7 steel strand wire 1, has increased the stretching resistance of cable; At 12 tin-coated copper twisted wires 2 of steel strand wire outer cladding, have the large effect of ampacity, the tin layer of tin-coated copper twisted wire 2 can prevent the aerial oxidation of copper; Also scribble rust preventive coating 3 outside tin-coated copper twisted wire 2, have the effect that prevents cable corrosion.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
