Accompanying drawing explanation
Fig. 1 is vertical section structure schematic diagram of the present utility model.
Fig. 2 is cross-sectional structure schematic diagram of the present utility model.
Embodiment
As shown in drawings; a kind of communication base station described in the utility model is with zooming out aerial cable; comprise inner core and outer protection layer; described inner core comprises cable conductor 1, is arranged on the insulating barrier 2 of cable conductor 1 outside, reinforcement 3 and gasket for packing 4; cable conductor 1, reinforcement 3 and gasket for packing 4 twist together, and outer protection layer comprises wrapped separator 5, vertical bag armour 6 and the sheath protective layer 7 that from-inner-to-outer sets gradually.
Described cable conductor 1 is for electrolytic aluminium bar is through drawing the aluminum steel cable conductor forming.Because aluminum metal is low more more and density is also little than copper metal price, electric conductivity also meets the demands, and according to cable, needs equal ampacity and existing copper aluminium calculation of price, and using copper conductor cost is approximately 5 times of left and right of aluminium conductor cost.The aluminium conductor that the utility model cable is used is lightweight, is more suitable for the built on stilts use of cable.In actual production, aluminium conductor does not allow joint, and has not allowed aborning scratch and discounting phenomenon, aluminium conductor D.C. resistance and mechanical performance should meet the requirement of standard GB/T/T3956-2008 regulation.
Described insulating barrier 2 is polyvinyl chloride cable Insulation Material extruded insulation layer, and thickness of insulating layer and mechanical electric performance should meet the requirement of communication industry standard YD/T1173-2010 regulation.
Described reinforcement 3 is coated reinforcement for phosphatization steel wire extrudes one deck black polyvinyl cable Insulation Material outward, phosphatization gauge of wire and tensile strength are according to every meter of construction weight of cable and built on stilts apart from accurate Calculation, guarantee that pulling force is the built on stilts carrying of actual use the more than 2.5 times of strength, the black polyvinyl cable Insulation Material extruding is easy to and insulated wire cores Division identification, and extrude thickness and be not less than 0.4mm
Reinforcement can need to be extruded insulating barrier with foamed material according to the construction of cable and control external diameter size, meets cable design structure needs.Prevent that aluminium core conductor from stretching in construction, bending causes the conductor-stretch core that breaks.The reinforcement insulating barrier increasing reduces the flashover discharge breakdown of the burr generation of phosphatization Steel Wire Surface in the time of can making cable detection, the most advanced and sophisticated burr of lightning induction and Steel Wire Surface also easily makes cable breakdown scrap in actual use, and rain leakage and insulating barrier aging blemiss also may make charged the hurting sb.'s feelings of phosphatization steel wire reinforcement sometimes.In the stranded process of cable cabling, adopt circular tungsten steel die to press, the aperture of tungsten steel die is controlled at than the large 0.2～0.3mm of cable twisting core external diameter, suitably control reinforcement tension force, increase some polypropylene mesh and tear gasket for packing, guarantee cable core rounding, range estimation can not overbending, it is wrapped that employing has the polyester belt double-layer overlapping of electrical insulation properties preferably, guarantees that polyester belt is wrapped tight, smooth, controls conductor assembly outer diameter uniform and stable.
Described vertical bag armour 6 is embossing composite steel-plastic belt, adopt embossing technique can increase cable bend performance, adopt glue sealing steel band lap gap place, while reducing cable bend, steel band lap-joint splits, and prevents that rain leakage protection against the tide from making the advantages such as insulating resistance of cable performance reduction.
Described sheath protective layer 7 adopts fire-retardant polyethylene cable protective cover material closely to extrude sheath protective layer; can extend cable ageing time; increase cable machinery intensity, once stop burning in cable outdoor fire disaster to prolong combustion and cause more major break down disaster, there is the features such as environmental protection.
The more advantages such as the cable manufacturing has that cost is low, antitheft without copper, anti-strong wind reverses and stretches, remote directly built on stilts, anti-shotgun gunslinging, service life length, good electric property, cables manufacturing structure is excellent, usage safety performance is high, be easy to mounting and installation, environmental protection zoom out aerial cable.Guarantee to zoom out aerial cable excellent quality, rational in infrastructure reliable, use safety, steady quality permanent.
Example recited above is only that the preferred implementation of the utility model cable design structure is described; not design of the present utility model and scope are limited; do not departing under the utility model design concept prerequisite; the various modification that in this area, common engineers and technicians make the technical solution of the utility model are improved and manufacture method; all should fall into protection range of the present utility model, the technology contents that the utility model is asked for protection is all documented in claims.
