Abstract
The invention provides a composite cable. The conductor material of the composite cable is mainly SrCeO3 series ceramic, wherein a ceramic base material accounts for 50 to 65 percent, graphite powder accounts for 30 to 40 percent, SrCeO3 accounts for 1 to 3 percent, and addictive accounts for 5 to 8 percent; and the ceramic base material, the graphite powder, the SrCeO3 and the addictive are mixed according to the proportion and fired into conductive ceramic which is used a cable core, and the joint of the cable core is connected by a metal joint so as to form a SrCeO3 ceramic composite material wire core transmission cable. The composite cable has obvious advantages that: with conductive characteristic in high temperature environment, SrCeO3 series high-temperature proton conductive ceramic is manufactured into the cable core with excellent performance, and copper consumption is saved; in addition, compared with copper, ceramic composite material has the advantages of conductivity, corrosion and high temperature resistance, high hardness, high strength, no toxicity, heat conduction, thermal shock resistance and other performance, lighter light, oxidation resistance and high stability, and the functions and service life of the composite cable are greatly improved.
Description
Technical field
The present invention relates to a kind of cable, especially a kind of composite cable.
Background technology
Modern electric line has following two kinds substantially: a kind of is overhead power line, and another kind is a power cable line.Owing to,,, when not allowing to set up shaft tower and lead, just need solve with power cable for the consideration of secure context and the restriction that is subjected to ground location perhaps in some special occasions in the intensive place of town dweller.The effect of power cable just is this.For network, cable all is vital for data and voice network.The propagation of data is finished by transmission signals on medium, and the medium of transmission signals can be copper conductor, optical cable or wireless transmission.For example, phone can pass through the mutual physical connection of telephone wire, and certain calling will arrive its destination, it must the road through a series of stube cable.
Cable is normally by the cable of several or the stranded similar rope that forms of several groups of leads [at least two every group], mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation, its conductor material major part is a copper, but the price of copper is more expensive, and people need performance to come instead of copper as the good cheap material of copper.
Summary of the invention
At the problems referred to above, the invention provides a kind of composite cable.
A kind of composite cable, its conductor material is mainly SrCeO
3System's pottery is characterized in that wherein ceramic base-material accounts for 50%-65%, and graphite powder accounts for 30%-40%, SrCeO
3Account for 1%-3%, additive is 5%-8%, with ceramic base-material, graphite powder, SrCeO
3With additive in proportion mixed sintering become conductivity ceramics, as cable core, the joint connects with metal joint, forms SrCeO
3Ceramic composite core transmission cable.
Remarkable result of the present invention is to utilize SrCeO
3It is high temperature modification proton conductive pottery conductive characteristic under hot environment, be made into the cable core of excellent performance, not only saved the consumption of copper, and compare with copper, ceramic composite generally have conductivity, corrosion-resistant, high temperature resistant, hardness is big, performance weight such as the intensity height is nontoxic, heat conduction, heat shock resistance are lighter, anti-oxidant (the easy oxidation of metal causes partial breakdown), the advantage of high stability increases its function and useful life greatly.
Description of drawings
Accompanying drawing is SrCeO
3The ceramic composite electric cable profile
Wherein: 1, sheath; 2, core; 3, SrCeO
3Conductivity ceramics; 4, insulating material.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing: the skin of cable is insulating sleeve 1 protection, is mainly SrCeO in its cable core 2
3 Conductivity ceramics 3, wherein ceramic base-material accounts for 50%-65%, and graphite powder accounts for 30%-40%, SrCeO
3Account for 1%-3%, additive is 5%-8%, with ceramic base-material, graphite powder, SrCeO
3With additive in proportion mixed sintering become conductivity ceramics, as cable core, the joint connects with metal joint, forms SrCeO
3Ceramic composite core transmission cable separates with insulating material 4 between the different cables.
The present invention is applied to utilize SrCeO in the cable machinery
3It is high temperature modification proton conductive pottery conductive characteristic under hot environment, be made into the cable core of excellent performance, not only saved the consumption of copper, and compare with copper, ceramic composite generally have conductivity, corrosion-resistant, high temperature resistant, hardness is big, performance weight such as the intensity height is nontoxic, heat conduction, heat shock resistance are lighter, anti-oxidant (the easy oxidation of metal causes partial breakdown), the advantage of high stability, its function and useful life are increased greatly, and can save the copper cash cost about 30%.
