Description

A kind of tension weather resistant composite conductor core overhead medium-pressure cable
Technical field
This utility model is related to technical field of electric wires and cables, specially a kind of tension weather resistant composite conductor core overhead medium-pressure Cable.
Background technology
Along with the continuous progress improving year by year with material science and technology of electricity needs, various capacity-improving conducting wires should on the market Transport and give birth to, the soft aluminum of carbon fiber complex core twists the plug that wire is the synthesis of Extra High Strength carbon fiber, substitute traditional steel core and steel twists Line, outer layer aluminum forms using the soft aluminum of arch is stranded, and carbon fiber composite core wire has the above transmission line of electricity of 500kV level and runs energy Power, tensile strength is higher, and the lighter feature of unit weight is so that apply the circuit of this kind of wire can reduce between shaft tower Wire hangs down radian, can improve the safety and reliability of circuit operation, meanwhile, can reduce support shaft tower quantity in transmission line of electricity, Reduce project occupation of land, economize the land resource, reduce engineering-built cost.
Midium voltage cable external diameter itself is larger, weight big, makes somebody a mere figurehead and needs when laying first to lay accordingly just twisted wire, and with linking up with Cable is pulled the weight that cable is born on steel strand wires with steel strand wires, laid processes are cumbersome, commonly outer shield is exposed to Corrosive environment and severe outdoor, in moist environment, can accelerated ageing, reduce the service life of cable, improve electric wire Cable be in the market in the urgent need to.
Utility model content
The purpose of this utility model is to provide a kind of tension weather resistant composite conductor core overhead medium-pressure cable, on solving State the problems such as external diameter in background technology is larger, weight is big, and rate of ageing is fast, cable service life is short.
For achieving the above object, this utility model provides following technical scheme:A kind of tension weather resistant composite conductor core frame Aerial voltage cable, including conductor, insulating barrier and band, described conductor is connected with semiconductive conductor shielding, described insulating barrier Inside is provided with semiconductive conductor shielding, and is coated with semi-conductive insulation shield outside insulating barrier, described semi-conductive insulation shield Outside be provided with copper strip shielding, be enclosed with packing outside described copper strip shielding, described band is connected with packing, described The outside of band is enclosed with oversheath.
Preferably, described conductor is carbon fiber complex core soft aluminium profiles wire.
Preferably, the material of described insulating barrier is Low Density Polyethylene.
Preferably, described band is non-woven fabrics.
Preferably, the material of described oversheath is weather resistant polyolefin.
Compared with prior art, the beneficial effects of the utility model are:This tension weather resistant composite conductor core overhead medium-pressure Cable, has all advantages of carbon fiber composite core cable, makes somebody a mere figurehead without in addition laying steel strand wires when laying, available carbon fiber is multiple Close core to bear the weight of cable, can directly make somebody a mere figurehead and lay, adopt weather resistant polyolefin oversheath simultaneously, increase to a certain extent The service life of cable, enable more stable, be rapidly performed by power transmission, preferably serve wires and cables industry.
Brief description
Fig. 1 is this utility model structural representation.
In figure:1st, conductor, 2, semiconductive conductor shielding, 3, insulating barrier, 4, semi-conductive insulation shield, 5, copper strip shielding, 6, Packing, 7, band, 8, oversheath.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme:A kind of tension weather resistant composite conductor core overhead medium-pressure Cable, including conductor 1, semiconductive conductor shielding 2, insulating barrier 3, semi-conductive insulation shield 4, copper strip shielding 5, packing 6, band 7 and oversheath 8, conductor 1 is connected with semiconductive conductor shielding 2, and conductor 1 is carbon fiber complex core soft aluminium profiles wire, available carbon Bearing the weight of cable, the safety and reliability that circuit runs is improved fiber composite core, and the inside of insulating barrier 3 is installed There is semiconductive conductor shielding 2, and outside insulating barrier 3, be coated with semi-conductive insulation shield 4, the material of insulating barrier 3 is gathered for low-density Ethylene, semiconductive conductor shielding 2, insulating barrier 3, semi-conductive insulation shield 4 adopt three-layer co-extruded, fixing more firm, semiconductive The outside of insulation shielding 4 is provided with copper strip shielding 5, is enclosed with packing 6 outside copper strip shielding 5, and band 7 is connected with packing 6 Connect, band 7 is non-woven fabrics, the outside of band 7 is enclosed with oversheath 8, and the material of oversheath 8 is weather resistant polyolefin, certain journey The service life of cable is increased on degree, decreases use cost, and any surface finish, smooth, bubble-free, crackle, impurity, machine Tool such as damages at the defect, and cable answers that lettering is correct, clear, anti-scratch.
Operation principle:When using this tension weather resistant composite conductor core overhead medium-pressure cable, conductor 1 adopts carbon fiber multiple Close core soft-type aluminum stranded conductor, carbon fiber composite core rod is by carbon fiber (35%), glass fibre (35%) and epoxy resin (30%) group Become, produced using continuous pultrude process, carbon fiber composite core rod wraps up by annealed aluminum wire, semiconductive conductor shielding 2, insulating barrier 3, half Conductive insulation shielding 4 adopt three-layer co-extruded, dry cross-linking technique is coated on outside composite conductor core, copper strip shielding 5 adopt one layer of weight The soft copper band of lap wound bag, rate is copper strips width to putting up between copper strips 15%, minimum be not less than 5%, then three core strandings, Packing 6 is filled and is tightened with non-woven fabrics, extrudes the polyolefinic oversheath of weather resistant 8 outside cable core, here it is tension weather resistant The whole process of composite conductor core overhead medium-pressure cable.
