The groove of helical form arrangement, described insulating barrier outer wall is fitted on the inside of described groove, set outside described metal ring layer
Outer insulation is equipped with, the sunk structure of helically direction arrangement is provided with described rubber spacer outer wall, described
Sponge is filled with inside sunk structure, the hand of spiral of described sunk structure is opposite with the hand of spiral of described groove.
Further, for the present invention is better achieved, bamboo-carbon layer is housed in described metal ring layer outer cover.
Further, for the present invention is better achieved, described metal ring layer is helically wound in institute for sheet metal bar
On the rubber spacer outer wall stated.
Further, to be better achieved the present invention, the spiral winding direction of described metal ring layer and described depression
The hand of spiral of structure is opposite.
Further, for the present invention is better achieved, antioxidation coating is provided with outside described outer insulation.
The present invention compared with prior art, has the advantages that：
(1) present invention is by using metal ring layer, it is possible to increase cable strength, it is to avoid aluminium alloy inside the extrusion damage of surface
Wire；
(2) present invention can realize the effect for absorbing moisture, while can by using the rubber spacer for being provided with sponge
Play the cushioning effect of external wall pressure power, it is to avoid aluminium alloy conductor is damaged；
(3) present invention can aid in the intensity for improving cable by using the spongy layer helically set, lifts it and resists
Draw performance.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention.
Reference：101. aluminium alloy conductor, 102. insulating barriers, 103. aramid fiber yarn center lines, 104. metal ring layers, 105. rubbers

Embodiment
The present invention is described in further detail with reference to specific embodiment, but embodiments of the present invention are not limited to
This.
Embodiment 1：
As shown in figure 1, a kind of moistureproof Compression-resistincable cable of coal yard machinery, including at least 3 aluminium alloy conductors 101 and it is arranged on aluminium
Insulating barrier 102 outside alloy lead wire 101, described aluminium alloy conductor 101 is helically wound on aramid fiber yarn center line 103,
Metal ring layer 104 is provided with outside described aluminium alloy conductor 101, rubber blanket is internally provided with described metal ring layer 104
Layer 105, is provided with the groove arranged in the shape of a spiral, the described outer wall of insulating barrier 102 patch on the described inwall of rubber spacer 105
Close on the inside of described groove, outer insulation 106 is provided with outside described metal ring layer 104, in described rubber blanket
The sunk structure 107 of helically direction arrangement is provided with 105 outer wall of layer, filled with sea inside described sunk structure 107
Silk floss, the hand of spiral of described sunk structure 107 is opposite with the hand of spiral of described groove.
When the present invention is by external compression, due to being provided with metal ring layer, the effect of protection aluminium alloy conductor can be played
Really；Because middle part is provided with aramid fiber yarn center line, wire can be enabled aluminum alloy to and be wrapped on aramid fiber yarn center line, enabled aluminum alloy to wire and resist
Pressure and tensile strength are bigger, it is not easy to impaired, meanwhile, the sponge in sunk structure is arranged on, absorption external water can be played
The effect divided, it is to avoid moisture enters inside aluminium alloy conductor, it is to avoid short circuit phenomenon.Closed in the present embodiment using groove direction with aluminium
The setting of golden wire in the opposite direction, can increase integrally-built tensile property, improve integrally-built intensity.
Embodiment 2：
In order to improve in integrally-built humidity resistance, the present embodiment, on the basis of embodiment 1, it is preferable that described
The outer cover of metal ring layer 104 be equipped with bamboo-carbon layer 108.By using bamboo-carbon layer, outside moisture can be adsorbed, because bamboo charcoal has
Reversible hygroscopic effect, after used a period of time, can make the moisture on the bamboo charcoal of corresponding site by way of drying
Volatilization.
In the present embodiment, it is preferable that described metal ring layer 104 is that sheet metal bar is helically wound in described rubber
On the outer wall of bed course 105.By using spiral canoe, the production of metal ring layer can be facilitated, meanwhile, it is capable to pass through
Mutually the mode of covering winding, strengthens the intensity of metal ring layer.
In order to improve in the tensile resistance of cable, the present embodiment, it is preferable that the spiral of described metal ring layer 104 is twined
It is opposite with the hand of spiral of described sunk structure 107 around direction.By using reverse spiral winding mode, cable can be made
When being stretched, metal ring layer and sunk structure produce reverse active force, so that it is avoided that quoit layer is stretched deformation,
It is favorably improved the intensity of metal ring layer.
Because open space electric power cable easily produces aging under light illumination, cable is caused to be easily damaged, in the present embodiment,
On the basis of embodiment 1, it is preferable that be provided with antioxidation coating 109 outside described outer insulation 106.
