Abstract
The utility model discloses an outdoor overhead installing or other geographical data cable suitable for high shielding requirements, which comprises a single conductor core consisting of a conductor and a conductor insulating course. Two conductor cores are intertwisted together to form a conductor pair; four conductor pairs are intertwisted together to form a subunit; from inside to outside of each subunit sequentially wound and wrapped are an aluminum plastic combined film, and a combined shielding course. The subunit wound and wrapped already are intertwisted again to form cables. The utility model has the advantages of strong anti jamming performance, excellent damp preventing and shielding effect, excellent physical and mechanical performance, and being cap[able of satisfying different installing requirements and different outdoor conditions.
Description
Technical field:
The utility model relates to a kind of data cable, especially a kind of outdoor built on stilts or buried data cable that is applicable to high shielding requirements.
Background technology:
The YD/T1019 standard that the former Ministry of Posts and Telecommunications formulates has only proposed requirement to indoor data cable, and but not at the concrete requirement of outdoor use cable regulation, therefore present cable factory is all to produce house cable.Because the condition difference of outdoor application environment is bigger, user's requirement also varies, and especially when outdoor built on stilts uses, former indoor data cable can not satisfy light aging in anti-day far away, the requirement of the serious interference of anti-outdoor electromagnetism.
Summary of the invention:
Goal of the invention of the present utility model is intended to overcome the defective of prior art, provides a kind of interference free performance and shield effectiveness good, is more suitable for for the outdoor built on stilts or buried data cable that lays use.
Concrete technical scheme of the present utility model is as follows:
The utility model comprises the single core that is made of conductor and insulating layer of conductor, it is right that two cores are twisted into line mutually, it is characterized in that: four pairs of line strands become subunit together, the wrapped successively from inside to outside aluminum-plastic composite membrane of each subunit, composite shielding layer, the stranded again stranding of subunit after wrapped.
Wrapped successively from inside to outside non-absorbent material of cable core behind the utility model stranding or water blocking layer, braid.
Four pairs of lines described in the utility model are to stranded with different twisting pitch.
Subunit described in the utility model is more than one or two, is filled with non-hygroscopic material or water blocking yarn between the space of each subunit.
Composite shielding layer described in the utility model is a woven shield or copper strips is wrapped, total screen of the wrapped composition of aluminum-plastic composite membrane.
Woven shield described in the utility model is the screen with circular copper wire or tinned wire braiding or aluminum-magnesium alloy wire braiding.
Aluminum-plastic composite membrane described in the utility model is a single-sided structure.
The utility model comprises built on stilts cabling, buried cabling, and to be that the cable core after wrapped is outer adopt double-deck outer jacket to built on stilts cabling; Buried cabling is that the cable core after wrapped adopts inner covering, armour outward and the oversheath that extrudes is formed outer jacket.
The sheath internal layer of the double-deck outer jacket of aerial cable described in the utility model is to extrude polyvinyl chloride, sheath skin for having the polythene material that extrudes of weather resistance; Perhaps the sheath internal layer is that polyethylene, sheath are outer for having the pvc material of weather resistance.
The inner covering of underground cable described in the utility model adopts wrapped or extrudes, and armour adopts the wrapped or steel wire winding in two steel band gaps, is steel wire during vertical laying, and oversheath adopts polyvinyl chloride or polyethylene to extrude.
The utlity model has following advantage:
1, each subunit all has independent composite shielding layer or total screen, makes shield effectiveness outstanding more superior.
2, non-absorbent material of Tian Chonging or water blocking yarn, wrapped non-absorbent material or waterstop have stoped entering of water effectively; The complete construction of cable has been guaranteed the serviceability of cable.
3, the double-deck sheath of built on stilts cabling employing has been guaranteed the mechanical strength of cable and has been stoped entering of moisture; The buried armour that lays has been guaranteed pressure that data cable bore and pulling force, has more excellent mechanical performance.
