Description
Technical field
The utility model relates to electric wire field, relates in particular to the fire-resistant carbon-fibre wire cable of a kind of flexible insulation.
Background technology
Along with the development of China's economic construction, the continuous growth of electricity needs, cable is also increasing as the demand of the carrier of delivery of electrical energy.But existing cable, such as conventional organic cable (plastic cable), there is defect in its insulation property, such as plastic insulating layer easily aging, non-refractory, the easy defect such as hardening; Conventional steel reinforced aluminium conductor, its electric property, wire performance are bad.
In addition, development along with China's economic construction, the continuous growth of electricity needs, cable is also increasing as the demand of the carrier of delivery of electrical energy, and mostly the cable conductor of current domestic use is steel reinforced aluminium conductor and aluminium alloy conductors steel, the weight of these wires is larger, resistance is larger, thereby cause transmission of electricity expense high, and operating temperature is lower, can not adapt to the operation under hot conditions, so electric power transfer becomes " bottleneck " of electric power industry development, various countries are all at research novel overhead power transmission road wire, to replace traditional steel reinforced aluminium conductor.
Carbon fiber composite core wire is compared and is had the following advantages with traditional steel-reinforced aluminum conductor:
(1) lightweight: the density of carbon fiber complex core be the density of steel be 1/4.Therefore, the shaft tower span of aerial cable can increase, and reduces tower bar number and is about 16% left and right, reduces floor space simultaneously.
(2) intensity is high, and Fracture Force is large.The hot strength of carbon fiber complex core cable is about 2399MPa, is 1.97 times of ordinary steel wire, is 1.17 times of high strength steel.
(3) conductance is high, and ampacity is large.Aluminum steel sectional area in same diameter carbon fiber complex core cable is 1.29 times of conventional steel-core-aluminium strand cable, and ampacity improves 29% left and right.
(4) line loss is little.Carbon fibre composite is a kind of nonmagnetic substance, when wire can not produce magnetic hysteresis loss and eddy current loss during by alternating current, presents less AC resistance.
(5) corrosion-resistant, long service life.Carbon fiber composite core rod has been avoided steel core electrochemical corrosion between aluminum steel and zinc-coated wire when energising, makes long-term use of aluminum conductor and ageing-resistant.
(6) coefficient of linear expansion is little, and sag is little.
But not enough, the wire span of making can't be very large for existing carbon fiber complex core intensity.
Finally, existing cable can not be realized communication function, also needs separately to establish a communication line and could meet communication function, causes and repeats wiring.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned defect that overcomes cable in prior art, provides a kind of flexible insulation fire-resistant carbon-fibre wire cable.
The utility model solves the technical scheme that its technical problem adopts:
The fire-resistant carbon-fibre wire cable of a kind of flexible insulation, it is characterized in that, comprise four conductor wire cores, at described four conductor wire cores, be coated with successively insulation lining, metallic sheath and non metallic sheath outward, between described four conductor wire cores and insulation lining, be filled with magnesium oxide insulated filler; Described conductor wire core center is carbon fiber complex core, and described carbon fiber complex core comprises carbon fiber wire and glass fiber, layer centered by carbon fiber wire, and many glass fibers are stranded in outside described carbon fiber wire; At described carbon fiber complex core, be coated with successively insulating barrier and protective layer outward; Also include stainless steel light unit, described stainless steel light unit is contained in described magnesium oxide insulated filler; Described stainless steel light unit forms for being placed in a stainless steel protection pipe by some optical fiber, and stainless steel protection pipe adopts loose tube structure, fills continuously water-blocking material, stainless steel protection pipe outer cladding layer of copper layer in stainless steel protection pipe space.
Further, described metallic sheath is seamless copper pipe.
Further, described non metallic sheath is plastic protective layer.
The beneficial effects of the utility model are: the copper by high conductivity is made conductor, make cable conduction rate of the present utility model high; Employing is not burnt, the magnesium oxide of high temperature resistant (2800 ℃) is made insulation material, and it insulate, fire protecting performance will be higher than common rubber or plastic insulating layer; At the non metallic sheath of ragged edge, plastics outer jacket, has good Anticorrosive Character; Adopt seamless copper pipe to make metallic sheath, have good bendability and flexibility; The all advantages with traditional carbon fibres composite core, but intensity is larger, can be used for the more severe areas of condition such as large leap, severely afflicated area after making wire, has broad application prospects; In addition, not only can conduct electricity, can also realize optical fiber communication.
