Description

A kind of corrugated copper tube inner wire water proof type wire armoring radio-frequency cable

Technical field

This utility model relates to a kind of corrugated copper tube inner wire water proof type wire armoring radio-frequency cable, and this cable is mainly used in Seabed, river course, inferior communication situation, there is signal transmitting effect function.

Background technology

The physical foam insulation radio-frequency cable that China is used in mobile communication, broadcast, military building-up at present, majority is used in Built on stilts lay, and some special occasions such as ocean, river course, buried when, existing physical foam insulation radio frequency electrical Cable can not meet the use requirement of environment, needs to increase extra safeguard procedures, can not increase safeguard procedures at some in construction Occasion, makes troubles to communication, and waterproof armored type radio-frequency cable can solve this problem.

Summary of the invention

In view of situation and the deficiency of existence of prior art, it is waterproof that this utility model provides a kind of corrugated copper tube inner wire Armored type radio frequency coaxial-cable, adds water proofing property and stretching resistance damage capability, the protection internal structure of cable, enables cable Steady operation under respective environment.

This utility model for achieving the above object, be employed technical scheme comprise that a kind of waterproof shaped steel of corrugated copper tube inner wire Silk armouring radio-frequency cable, including inner wire, physical blowing foam polyethylene insulation, embossing outer conductor, polyethylene inner sheath, blocks water Layer, plastic-coated aluminium strip, outer protective polyethylene set, steel wire armor layer, pe sheath, it is characterised in that: described inner wire is wrinkle copper Pipe inner wire, protects in being sequentially provided with inner wire, physical blowing foam polyethylene insulation, embossing outer conductor, polyethylene outside inner wire Set, water blocking layer, plastic-coated aluminium strip, outer protective polyethylene set, steel wire armor layer, pe sheath.

The beneficial effects of the utility model are: in this cable, and inner wire is corrugated copper tube inner wire, and adds polyethylene Inner sheath I, water blocking layer, plastic-coated aluminium strip, polyethylene inner sheath II, steel wire armor layer, improve product in ocean, river course, buried When waterproof and tension disconnected wait ambient adaptability.

Accompanying drawing explanation

Fig. 1 is cross section structure schematic diagram of the present utility model.

Detailed description of the invention

As it is shown in figure 1, a kind of corrugated copper tube inner wire water proof type wire armoring radio-frequency cable, send out including inner wire 1, physics Cellular polyethylene insulation 2, embossing outer conductor 3, pe sheath 9, also include polyethylene inner sheath 4, water blocking layer 5, plastic-coated aluminium strip 6, outer protective polyethylene set 7, steel wire armor layer 8.

Inner wire 1 is corrugated copper tube inner wire, is sequentially provided with inner wire 1, physical blowing foam polyethylene exhausted outside inner wire 1 Edge 2, embossing outer conductor 3, polyethylene inner sheath 4, water blocking layer 5, plastic-coated aluminium strip 6, outer protective polyethylene set 7, steel wire armor layer 8, poly- Ethylene sheath 9.

Technical process,

1, inner wire processing: prick stricture of vagina production line by inner wire copper strips molding, vertical weldering, embossing, shape with inner wire welding fabrication Become corrugated copper tube inner wire.

2, insulation processing: extrude physical blowing foam polyethylene insulation 2 outside corrugated copper tube inner wire.

3, outer conductor processing: by physically foamed pe insulation core, pricking stricture of vagina production line with outer conductor welding fabrication will outward Conductor copper strips molding, vertical weldering, embossing, form embossing outer conductor 3.

4, inner sheath processing: squeeze black linear low density polyethylene inner sheath 4 outside outer conductor.

5, water blocking layer processing: complete the processing of water blocking layer 5 at the outer wrapped waterstop of polyethylene inner sheath 4.

6, oversheath processing: mould aluminium strip 6 in the outer vertical coating of water blocking layer 5 and extrude outside black linear low density polyethylene with machine Sheath 7.

7, steel wire armor layer processing: in outer protective polyethylene set 7 outer processing steel wire armor layer 8.

8, sheath processing: extrude black linear low density polyethylene sheath 9 outside steel wire armor layer 8, and complete with machine lettering Become processing.
