Abstract

The invention provides a composite cable with high performance. The conductor material of the composite cable is mainly SrCeO3 series ceramic and carbon fiber, 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 an inner core, the carbon fiber is used as an outer core, and the joint of the cable core does not need to be disconnected and is connected by a carbon fiber joint so as to form a composite material wire core transmission cable with high performance. The composite cable has obvious advantages that: with the conductivity, SrCeO3 series ceramic is manufactured into the cable core with excellent performance, and copper consumption is saved; in addition, compared with copper, the 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

A kind of high-performance composite cable

Technical field

The present invention relates to a kind of cable, especially a kind of high-performance 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 high-performance composite cable.

A kind of high-performance composite cable, its conductor material is mainly SrCeO ₃Be pottery and carbon fiber, it is characterized in that wherein ceramic base-material accounts for 50%-65%, 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 inner core, carbon fiber is as outer core with conductivity ceramics, the joint need not to disconnect, and connects with the carbon fiber joint, forms high-performance composite materials 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, composite material 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 a high-performance composite cable profile

Wherein: 1, sheath; 2, the outer core of carbon fiber; 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 ₃The outer core 2 of conductivity ceramics 3 and carbon fiber, 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 the cable core inner core, carbon fiber is as outer core, the joint need not to disconnect, and connects with the carbon fiber joint, forms high-performance composite materials core transmission cable, separates with insulating material 4 between the different cables.

The present invention is applied to utilize SrCeO in the cable machinery₃Be that the high temperature modification proton conducting ceramics temperature is at height Conductive characteristic under the temperature environment is made into the cable core of excellent performance, has not only saved the consumption of copper, and And compare with copper, composite generally have electric conductivity, corrosion-resistant, high temperature resistant, hardness is big, intensity is high not to be had The performance weight such as poison, heat conduction, heat shock resistance are lighter, and anti-oxidant (the easy oxidation of metal causes partial breakdown), The advantage of high stability greatly increases its function and service life, and can save about 30% The copper cash cost.
