Description
Technical field
The utility model belongs to lightning protection downlead technical field, relates in particular to a kind of composite material downlead.
Background technology
At present, China is in fields such as electric power, communication, lightning protections, and the metallic article using is not corrosion-resistant, easily get rusty.For mitigate corrosion, downlead generally adopts galvanized steel bar, but moves after 5-6, and corrosion still unavoidably occurs, once occur after corrosion, can accelerated corrosion under the effect of galvanic corrosion.
The sectional area of existing downlead diminishes or disconnects because of local heavy corrosion, the lightning current ability of releasing is restricted, while causing the thunderbolt such as lightning rod and steel tower, lightning current can not cause the earth by downlead by lightning current in time, easily there is back flashover accident, therefore existing galvanized steel bar downlead renovates, and engineering is frequent, waste material, and integrated cost is high; Useful life is short; The waste water that existing galvanized steel bar downlead produces in the time producing simultaneously etc. are seriously polluted.
Utility model content
Technical problem to be solved in the utility model is: a kind of composite material downlead is provided, with solve existing downlead not corrosion-resistant, easily get rusty, useful life is short, the engineering that renovates is frequent, the technical problem that integrated cost is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: composite material downlead, comprise the graphite core and the insulating barrier that are set together from inside to outside, described insulating barrier comprises the first rubber layer, metal level and the second rubber layer that are set together from inside to outside.
Improve as one, in described graphite core, be provided with and strengthen silk.
Improve as one, described graphite core comprises some graphite wire harness.
As further improvement, described graphite wire harness is linearly arranged.
As further improvement, between described graphite core and insulating barrier, be provided with graphite line braid.
Adopt after technique scheme, the beneficial effects of the utility model are: because the main material of the graphite core of composite material downlead is graphite, adopt graphite core to substitute the metal material in original downlead, effectively avoid corrosion of metal, and graphite is high temperature resistant, therefore improve the thermal stability of downlead; Because described insulating barrier comprises the first rubber layer, metal level and the second rubber layer that are set together from inside to outside, adopt rubber can play the effect of insulation again, can protect inner graphite core not to be damaged simultaneously; And the metal level in insulating barrier can increase the intensity of insulating barrier, further the inner graphite core of protection is not damaged simultaneously.The composite material downlead that the utility model provides, low cost of manufacture, conductivity is outstanding, and its graphite core is corrosion-resistant, can adapt to various environment, is difficult for being corroded, and insulating barrier can play insulating effect, also can further protect inner graphite core; Long service life, has reduced the number of times of the engineering that renovates, and has saved material, has reduced engineering cost; And while in process of production, effectively having avoided former downlead to produce because of the environmental pollution of zinc-plated generation.
Strengthen silk owing to being provided with in graphite core, increased toughness and the tensile strength of graphite core.
Owing to being provided with graphite line braid between described graphite core and insulating barrier, thereby by graphite line braid, some graphite wire harness are carried out fasteningly, increased conducting effect.
Because graphite core is the graphite core that flexible graphite or high-carbon graphite are made, thereby improve the conductivity of graphite core.

As shown in Fig. 1 to Fig. 3 is common, a kind of composite material downlead, comprise the graphite core 1 and the insulating barrier 2 that are set together from inside to outside, because the main material of graphite core 1 is graphite, adopt graphite core 1 to substitute the metal material in original downlead, effectively avoided corrosion of metal, and graphite is high temperature resistant, has therefore improved the thermal stability of downlead; Insulating barrier 2 comprises the first rubber layer 21, metal level 22 and the second rubber layer 23 that are set together from inside to outside, adopts rubber can play the effect of insulation, can protect inner graphite core 1 not to be damaged simultaneously; And the metal level 22 in insulating barrier 2 can increase the intensity of insulating barrier 2, further the inner graphite core 1 of protection is not damaged simultaneously.
In order to increase toughness and the tensile strength of graphite core 1, in graphite core 1, be provided with and strengthen silk.
Graphite core 1 comprises some graphite wire harness 11, and graphite wire harness 11 is linearly arranged.
In order to increase conducting effect, between graphite core 1 and insulating barrier 2, be provided with graphite line braid 12, by graphite line braid 12, some graphite wire harness 11 are carried out fastening, thereby increase conducting effect.
In order to improve the conductivity of graphite core 1, graphite core 1 is the graphite core 1 that flexible graphite or high-carbon graphite are made.
The composite material downlead that the utility model provides, not only can be applied to lightning arrester downlead, can also be applied to the multiple occasions such as lightning protection, anti-static grounding, protective earthing, working earthing.
The composite material downlead that the utility model provides, low cost of manufacture, conductivity is outstanding, and its graphite core 1 is corrosion-resistant, can adapt to various environment, is difficult for being corroded, and insulating barrier 2 can play insulating effect, also can further protect inner graphite core 1; Long service life, has reduced the number of times of the engineering that renovates, and has saved material, has reduced engineering cost; And while in process of production, effectively having avoided former downlead to produce because of the environmental pollution of zinc-plated generation.
