Abstract
The invention discloses a tensile type insulating aerial cable which comprises a composite conductor and an insulating layer extruded outside the composite conductor; the composite conductor comprises an inner core conductor and an outer layer conductor coated outside the inner core conductor. An inner core of the tensile type insulating aerial cable adopts a zinc plating steel stranded wire, which has larger tensile strength and cable roundness; and the zinc plating steel stranded wire also has a current carrying effect, so that the current carrying quantity of the cable is increased, and the tensile type insulating aerial cable has better tensile strength and roundness, prevents the problem that an outer sheath of the cable is cracked, and is suitable for being laid in a great height difference and span environment.
Description
Technical field
The present invention relates to the power cable field, specifically a kind of tensile type aerial insulated cable.
Background technology
At present, aerial insulated cable is as a class cable of electric energy transmitting, for remarkable contribution has been made in the development of China's electric utility.Along with industrial expansion, the overlay area of electric power network is more and more wider, and overlay area also becomes increasingly complex.Common aerial insulated cable is the pattern that adopts copper wire or aluminium wire stranded conductor, has increased so the total weight of cable.The cable laying of some large specification length is in the larger environment of height fall is arranged, tend to be damaged and even break because of the cable deadweight, particularly rain freeze, the impact of the harsh weather such as ice and snow weather, the aerial insulated cable cable likely causes the electric power signal Transmission because freezing, and causes the economic loss that can't save.
Summary of the invention
The invention provides a kind of tensile type aerial insulated cable, have tensile strength and roundness preferably, effectively prevented again the problem of cable jacket cracking.
A kind of tensile type aerial insulated cable of the present invention, this cable are by composite conductor and be extruded in the outer insulating barrier of composite conductor and form; Described composite conductor is by interior core conductor and be coated on the outer outer contact of interior core conductor and form.
Further improve, described interior core conductor has adopted the galvanized strand wires structure.
Further improve, described outer contact adopts the 2nd class conductor structure, adopts regular stranded mode, its surperficial rounding.
Beneficial effect of the present invention is: 1, the inner core of this cable has adopted galvanized strand wires, has both had larger tensile strength, has again the roundness of cable, and galvanized strand wires also can play the effect of current-carrying, so also increased the ampacity of cable.2, this cable has tensile strength and roundness preferably, has effectively prevented again the problem of cable jacket cracking, is adapted at laying in the larger environment of height fall and span.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of tensile type aerial insulated cable of the present invention, this cable are by composite conductor and be extruded in the outer insulating barrier 3 of composite conductor and form; Described composite conductor is by interior core conductor 1 and be coated on interior core conductor 1 outer outer contact 2 and form.
Appeal described interior core conductor 1 and adopted the galvanized strand wires structure, both had larger tensile strength, have again the roundness of cable, galvanized strand wires also can play the effect of current-carrying, so also increased the ampacity of cable; Described outer contact 2 adopts the 2nd class conductor structure, adopts regular stranded mode, its surperficial rounding; This tensile type cable has tensile strength and roundness preferably, has effectively prevented again the problem of cable jacket cracking, is adapted at laying in the larger environment of height fall and span.
The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
