Abstract
The utility model relates to a kind of 13/8 aluminium outer conductor radiation high-power leaky radio-frequency cable, and this cable is widely used in the occasions such as mountain area, subterranean railway, underground highway, parking lot, mining site and indoor communication, has Signal transmissions effect and antenna function.Physically foamed pe insulation layer, aluminium strip outer conductor, flame-retardant polyolefin sheathed is provided with outward successively at corrugated copper tube inner wire; Aluminium strip outer conductor is tubulose, and on a face of tubular outer conductor, interval is equidistantly provided with several rectangular opening.Beneficial effect is: on the tubular body of aluminium strip outer conductor, and interval has equidistantly rushed several uniform rectangular opening, ensure that the consistency of opening, improves product coupling attenuation performance index.Aluminium strip outer conductor replaces copper strips outer conductor, significantly reduces product cost.Adopt corrugated copper tube inner wire, the flexibility of this specification cable can be increased, be beneficial to engineering construction.
Description
Technical field
The utility model relates to a kind of 13/8 aluminium outer conductor radiation high-power leaky radio-frequency cable, and this cable is widely used in the occasions such as mountain area, subterranean railway, underground highway, parking lot, mining site and indoor communication, has Signal transmissions effect and antenna function.
Background technology
Leaky coaxial cable can be used for the region that general communication antenna is difficult to play a role, and now widely used leaky cable outer conductor mostly adopts fluting corrugated copper tube form, on the corrugated copper tube outer conductor welded, by groover, outer conductor is outputed osculum.Because the cutter of slotting used needs frequent replacing to cause the osculum irregularity outputed, cause maximum coupling attenuation index bad.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of 13/8 aluminium outer conductor radiation high-power leaky radio-frequency cable, and aluminium strip outer conductor goes out rectangular opening, improves regularity and the coupling attenuation index of opening shape.
The utility model for achieving the above object, the technical scheme taked is: a kind of 13/8 aluminium outer conductor radiation high-power leaky radio-frequency cable, it is characterized in that: comprise corrugated copper tube inner wire, physically foamed pe insulation layer, aluminium strip outer conductor, flame-retardant polyolefin sheathed, described corrugated copper tube inner wire is provided with physically foamed pe insulation layer, aluminium strip outer conductor, flame-retardant polyolefin sheathed outward successively; Described aluminium strip outer conductor is tubulose, and on a face of tubular outer conductor, interval is equidistantly provided with several rectangular opening.
The beneficial effects of the utility model are: on the tubular body of aluminium strip outer conductor, and interval has equidistantly rushed several uniform rectangular opening, ensure that the consistency of opening, improve product coupling attenuation performance index.Aluminium strip outer conductor replaces copper strips outer conductor, significantly reduces product cost.Adopt corrugated copper tube inner wire, the flexibility of this specification cable can be increased, be beneficial to engineering construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Fig. 1, a kind of 13/8 aluminium outer conductor radiation high-power leaky radio-frequency cable, comprises corrugated copper tube inner wire 1, physically foamed pe insulation layer 2, aluminium strip outer conductor 3, flame-retardant polyolefin sheathed 4.
At corrugated copper tube inner wire) outside extrude one deck physically foamed pe insulation layer 2, after outer conductor is passed through the operation such as embossing, punching with aluminium strip, vertical wrapping in outside physically foamed pe insulation layer 2 forms aluminium strip outer conductor 3, ensure that the intensity of outer conductor, and improve coupling attenuation index, outside aluminium strip outer conductor 3, extrude flame-retardant polyolefin sheathed 4 by sheath infrastructure device.
Aluminium strip outer conductor 3 is tubulose, and on a face of tubular outer conductor, interval is equidistantly provided with several rectangular opening 3-1.
The geomery of rectangular opening 3-1 is determined according to the change of the frequency of utilization of cable, during the shape of rectangular opening 3-1 of the present utility model is mainly used in, low frequency communication.
This cable size is: 13/8 cun.
