Further, for realizing the utility model better, between described heat-insulating layer and described copper mesh, be provided with epoxy resin layer, described copper mesh is embedded in described epoxy resin layer.
Further, for realizing the utility model better, in the space between described steel core and described environmental protection insulating protective layer, be provided with aramid fiber yarn.
Further, for realizing the utility model better, described aluminium alloy conductor is along described steel core outer wall winding arrangement in the shape of a spiral.
Further, for realizing the utility model better, be fitted in inside described heat-insulating layer on described environmental protection insulating protective layer outer wall.
The utility model compared with prior art, has following beneficial effect:
(1) the utility model is by adopting bamboo-carbon layer, can adsorb the moisture entered in outer insulation, the airing when high temperature, and bamboo-carbon layer can be made to recover dry, thus continues to realize water suction moisture effect;
(2) the utility model is by adopting flanged structure, can play along cable bearing of trend guide functions, makes the moisture concentrated in bamboo-carbon layer concentrate flowing, facilitates cable to dewater as early as possible;
(3) the utility model is by adopting environmental protection insulating protective layer and heat-insulating layer, can realize dual waterproof effect, improves the water resistance of aluminium alloy conductor in cable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, be to be understood that, the following drawings illustrate only some embodiment of the present utility model, therefore the restriction to scope should be counted as, for those of ordinary skill in the art, under the prerequisite not paying creative work, other relevant accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model overall structure schematic diagram.
Wherein: 101. aluminium alloy conductors, 102. environmental protection insulating protective layers, 103. heat-insulating layers, 104. steel cores, 105. inner insulation layers, 106. bulge-structures, 107. bamboo-carbon layers, 108. outer insulations, 109. epoxy resin layers, 110. copper mesh.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1, a kind of waterproof and dampproof aluminium alloy cable, comprise the aluminium alloy conductor 101 that steel core 104 and circular array are arranged in described steel core 104 outside, in described aluminium alloy conductor 101 outer cover, environmental protection insulating protective layer 102 is housed, heat-insulating layer 103 is had in described environmental protection insulating protective layer 102 outer setting, in described heat-insulating layer 103 outer cover, copper mesh 110 is housed, in described copper mesh 110 outer cover, inner insulation layer 105 is housed, the described outside uniform intervals of inner insulation layer 105 is provided with bulge-structure 106, bamboo-carbon layer 107 is provided with between described bulge-structure 106, in described bulge-structure 106 outer cover, outer insulation 108 is housed.
When outer insulation 108 is impaired, moisture enters outer insulation inside, under the suction-operated of bamboo-carbon layer, attachment of moisture, on bamboo-carbon layer, owing to being provided with bulge-structure, makes moisture concentrate along bulge-structure bearing of trend, thus when lower position, can whereabouts be concentrated; Because bamboo charcoal has reversible adsorption effect, therefore, when weather takes a turn for the better or temperature raises, the moisture be attached on bamboo-carbon layer can be evaporated, and bamboo-carbon layer can continue to realize soaking effect.
Owing to arranging copper mesh structure, certain protective effect can be played to heat-insulating layer, meanwhile, avoid thicker heat-insulating layer to affect cable flexible; Because the aluminium alloy conductor outside in heat-insulating layer is also provided with environmental protection insulating protective layer; therefore; moisture is difficult to damage aluminium alloy conductor by inner insulation layer, heat-insulating layer and environmental protection insulating protective layer three-decker, thus ensures overall waterproof and dampproof performance.
