Description
Technical field
The present invention relates to a kind of power transmission cable, specifically, related to a kind of aerial insulated cable that is provided with carbon fiber composite core rod.
Background technology
Common aerial insulated cable has the following advantages: as dwindle the cable infall spacing and parallel distance, lay convenient, flexibility is high, reduce occupation space, significantly reduce the frequency of power cut that causes because of line fault and electric shock accidents, the fail safe of raising electrical network and reliability etc.
But common aerial insulated cable is in the mountain area or physical features when having the bigger place of drop and span to lay, and cable tends to because self overweight generation is seriously dangled, and can't normally move.In order to address these problems, often need increase the quantity of shaft tower, increase and lay cost, it is less that cable dangles simultaneously, the shaft tower increase causes ampacity to compare, and transmission loss is relatively big.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The objective of the invention is the deficiency to prior art, thus provide a kind of design science, functional, stretching resistance strong and reduce the aerial insulated cable that sets up cost.
To achieve these goals; The technical scheme that the present invention adopted is: a kind of aerial insulated cable; Comprise conductor wire core, insulating barrier, carbon fiber composite core rod and conductor wire core screen, wherein, said conductor wire core is stranded on the said carbon fiber composite core rod; Said conductor wire core screen is wrapped on the said conductor wire core, and said insulating barrier is wrapped on the said conductor wire core screen.
Based on above-mentioned, said conductor wire core is the multiply core, and said multiply core is stranded on the said carbon fiber composite core rod.
Based on above-mentioned, said conductor wire core screen is the conductor wire core screen that is made up of cross-linking type semiconductive material or non-crosslinked type semiconductive material.
Based on above-mentioned, said insulating barrier is the insulating barrier that is made up of with black cross-linkable polyethylene insulation material or black weatherability high density polyethylene (HDPE) mix insulation material aerial insulated cable.
The relative prior art of the present invention has outstanding substantive distinguishing features and obvious improvement, and specifically, the present invention is different with traditional aerial insulated cable; It increases has carbon fiber composite core rod and conductor wire core screen, and wherein, said conductor wire core can be set to multiply according to the transmission of electricity demand; The said conductor wire core of multiply is stranded on the said carbon fiber composite core rod; Said carbon fiber composite core rod adopts the carbon fiber glass-epoxy to be composited, and resistance to tension is strong, during laying; Strain the two ends of this aerial insulated cable; Can effectively solve aerial insulated cable in the mountain area or physical features when having drop and the bigger place of span to lay because the problem that self overweight generation is seriously dangled, its have design science, functional, stretching resistance strong and reduce the advantage of setting up cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Through embodiment, technical scheme of the present invention is done further detailed description below.
A kind of aerial insulated cable; Comprise conductor wire core 2, insulating barrier 4, carbon fiber composite core rod 1 and conductor wire core screen 3; Wherein, Said conductor wire core 2 is stranded on the said carbon fiber composite core rod 1, and said conductor wire core screen 3 is wrapped on the said conductor wire core 2, and said insulating barrier 4 is wrapped on the said conductor wire core screen 3.
Based on above-mentioned, said carbon fiber composite core rod 1 adopts the carbon fiber glass-epoxy to be composited, and its density is about 1.9 g/cm3, and tensile strength is 2399Mpa, increases the resistance to tension of whole aerial insulated cable; Because the resistance to tension of this aerial insulated cable is strong, in the mountain area or physical features when having drop and the bigger place of span to lay, need not to increase the quantity of shaft tower, reduce and lay cost.
Based on above-mentioned; According to difference transmission of electricity demand, said conductor wire core 2 can be the multiply core, and said multiply core is stranded on the said carbon fiber composite core rod; Adopt stranded mode that conductor wire core is wrapped in said carbon fiber composite core rod, make this aerial insulated cable compact conformation; Said conductor wire core can adopt various materials such as copper, aluminium or alloy material to process, and in order better to alleviate the weight of this aerial insulated cable, adopts soft aluminum to make said conductor wire core.
Based on above-mentioned; Adopt soft aluminium conductor wire core to be stranded on the said carbon fiber composite core rod 1; Reduce twisting pitch for increasing its flexibility; Said soft aluminium conductor wire core is designed suitable cross-sectional area of conductor according to the requirement of the conveying capacity of electrical network, according to the specification and the quantity of the suitable trapezoidal single line of soft aluminium of section selection, will have the aluminium bar squeezes out corresponding specification on extruder soft aluminium conductor wire core then now.
Based on above-mentioned, said conductor wire core screen 3 is cross-linking type semiconductive material screen or non-crosslinked type semiconductive material screen.
Based on above-mentioned, said insulating barrier 4 is that aerial insulated cable is with black cross-linkable polyethylene insulation material insulating barrier or black weatherability high density polyethylene (HDPE) mix insulation material insulating barrier.
Based on above-mentioned, said conductor wire core screen 3 can layering be extruded or extrude separately on plastic extruding machine with said insulating barrier 4; The speed of the working temperature of plastic extruding machine various piece, the rotating speed of screw rod, traction is up to specification, with reference to the suitable mould of the size Selection of core, can not be eccentric during unwrapping wire, and each parts are wanted co-ordination.Guarantee that bright and clean, smooth, the no flake of said conductor wire core screen and said surface of insulating layer, color and luster are even etc.
This aerial insulated cable had both had the advantage of traditional aerial insulated cable, simultaneously, was provided with carbon fiber composite core rod in this aerial insulated cable; Improved the resistance to tension of this aerial insulated cable; Said conductor wire core is stranded on the said carbon fiber composite core rod, and compact conformation has improved the ampacity of cable and reduced transmission loss; Simultaneously, alleviated the weight of whole aerial insulated cable.This aerial insulated cable is carbon fiber composite core rod, conductor wire core, conductor wire core screen and insulating barrier from inside to outside successively; The laying requirement of big capacity, low arc drop, low energy consumption, large span be can satisfy, cities and towns, high stored building group, tourism development zone, greenbelt, mountain area are applicable to.
Should be noted that at last: above embodiment is only in order to technical scheme of the present invention to be described but not to its restriction; Although with reference to preferred embodiment the present invention has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can specific embodiments of the invention make amendment or the part technical characterictic is equal to replacement; And not breaking away from the spirit of technical scheme of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
