The technical solution adopted for the present invention to solve the technical problems is:
A kind of high purity carbon fiberreinforced aluminium alloy conductor is from thermometric composite cable, it is characterized in that, comprise several conductor, the outside of several conductor is enclosed with insulating barrier respectively, be provided with elastomer between the several conductors being enclosed with insulating barrier, elastomer cross section is the quadrangle of four limit indent cambers; Be provided with fibre reinforced core inside elastomer, described fibre reinforced core comprises carbon fiber wire and ceramic fibre silk, after the carbon fiber wire and ceramic fibre skein silk that become stock being closed, adopts resin-dipping, then adopts curing oven to form; The outside being enclosed with four conductors of insulating barrier is enclosed with belting layer, restrictive coating successively, is annularly distributed with several through hole in restrictive coating, and through hole cross section is oval; Described belting layer is the overlapping wrapped formation of multi-layer nonwoven fabrics; A light unit is set being enclosed with in the space between the conductor of insulating barrier and belting layer, described light unit comprises multifiber and the Loose tube set gradually from inside to outside, non-metal reinforced layer and sheath, described Loose tube is enclosed within outside described optical fiber, full dry type water-blocking material is filled in described Loose tube, be provided with many equally distributed water blocking yarns in described non-metal reinforced layer, be embedded with between described non-metal reinforced layer and described sheath and tear rope; At least one optical fiber is inscribe the grating fibers having thermometric grating, and grating fibers forms a grating point for measuring temperature at interval of predetermined distance, and predetermined distance is 300-500 rice.
The invention has the beneficial effects as follows:
Novel structure of the present invention; elastomer is provided with between the insulating barrier of several conductor; annularly through hole is distributed with in restrictive coating; slow down ambient pressure; the conductor protecting cable is injury-free, insulating barrier is damaged can not directly contact; it is unobstructed that the information that ensure that is transmitted; conductor adopts aluminum alloy materials; security performance is better than copper core cable; in addition, the ballistic properties of this aluminium cable is less than copper cable by 40%, and flexility is higher than copper cable by 24%; because the weight of aluminium alloy cable is only 50% of copper cable, also effectively installation cost can be reduced.Realizing on same electric property basis, the direct purchase cost of aluminium alloy cable is lower than copper cable by 40%, and common buildings installation expense can save more than 20%.Peter out in copper resource, when cabling requirements continues to increase, aluminum alloy cable can save great amount of investment.
Have employed ceramic fibre and carbon fiber composite structure, not only there is the advantage of carbon fibre material, and intensity is larger.
As used cable of the present invention in actual production, both can normal transmission of electric energy, can communication be carried out again, self can also carry out temperature survey.Which offers a saving the equipment such as ADSL, the OPGW increased in order to power communication, also can reduce the accidents such as the thunderbolt caused because of OPGW and threaten.The GPS wire temperature measuring equipment of the use taked at present work very high cost can also be saved in addition, save huge cost.Using cable of the present invention as the circuit of transferring electric power time, staff directly can determine the actual bearer situation of circuit to line temperature according to described traverse survey.
The present invention to reinforcement wire on-line monitoring, grasp variations in temperature, improve wire transmission capacity, reduce line loss, improve safe operation of electric network, increase communication backup, solve comprehensive communication plan etc. aspect and all show and provide large economic benefit and social benefit, especially build in environment-friendly type, the controlling the trend of economical society in country instantly with all strength and more demonstrate powerful realistic meaning.
