Abstract
The utility model relates to an insulation cable, and especially relates to a bunched overhead insulation cable. The drag cable comprises three main cores, each main core contains a twisted conductor, an separating layer, an insulating layer and an insulation external layer are coated outside the conductor in order, a cable core winding layer and an outer sheath are coated outside three main cores, the aramid fiber which opposites the twist direction and conductor twist direction is provided in each main core; a group of rubber filling strips which take high soft low carbon galvanized steel wire as a support is provided in the cable core winding layer, one of the rubber filling strip is provided among three main cores, and others are provided outside three main core conductors. The drag cable is capable of prolonging the cable life of a travelling crane, reducing the influence of the production activity of the enterprises, and helping the enterprises to reduce the cost.
Description
Technical field
The utility model relates to insulated cable, relates in particular to bunched aerial insulated cable.
Background technology
Driving is very important as the important handling equipment in the middle of the industrial and mining enterprises workshop to activity in production.Because driving will move back and forth in orbit, for the flexible cable of its outfit will frequently be pulled.So, the flexible cable insulation can be broken and conductor wherein is same because being subjected to frequently to stretch the meeting of bending quick aging.
At present, the cable for travelling crane life-span on the market is generally less than two months, and price is high.Frequent cable then operation cost of enterprises is high, and affects activity in production.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of day automobile-used drag cable is provided.The utility model can prolong the cable for travelling crane life-span, reduces the impact on enterprise's activity in production, helps Reducing Cost in Enterprises.
For addressing the above problem, a kind of day automobile-used drag cable, it comprises the three beams master core, every bundle master core contains stranded conductor, conductor is surrounded by separator, insulating barrier and insulating outer layer isolation outward successively, three beams master core outer wrapping core wrap and oversheath also are provided with in described every bundle master core and the stranded opposite aramid fiber of direction of lay and conductor; Also be provided with one group in the described core wrap and do the rubber packing of support with highly-flexible low-carbon (LC) zinc-coated wire, one of them is located in the middle of the three beams master core conductor, and all the other are located at outside the described three beams master core conductor.
Described day automobile-used drag cable, the insulating outer layer isolation of described main fibre core is outer to be polyester film.
Conductor of the present utility model adopts the standard that is better than 5 class conductors among the IEC60228, requires percentage elongation 20% in percentage elongation 〉=23%(standard).Added multiply high strength aramid fiber during the conductor bunch inside, solely the conductor strand of layer aramid fiber was opposite with other strand direction of lay when conductor was stranded, had guaranteed that like this cable has good flexibility, anti-distorting stress, good axial compression and degree of crook.Insulated wire cores is outer around one deck polyester film, guarantees that cable has good slipping property between the insulated wire cores when bending is used.In the centre of cable core with peripheral added the rubber packing that highly-flexible low-carbon (LC) zinc-coated wire is done support, make cable that high mechanical stress and flexibility be arranged when cable core is stranded.
Use detection through reality, this structural cable cable core intensity is large, anti-frequent bending.Less than two months, extend to four to six months by original useful life.Effectively reduce the harmful effect that the cable life weak point produces enterprise.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model schematic cross-section.
Embodiment
As shown in Figure 1, a kind of day automobile-used drag cable, it comprises three beams master core 1, every bundle master core contains stranded conductor, conductor is surrounded by separator 2, insulating barrier 3 and insulating outer layer isolation 6 outward successively, three beams master core outer wrapping core wrap 7 and oversheath 8 are in described every bundle master core 1 and direction of lay and the stranded opposite aramid fiber of conductor; Also be provided with one group in the described core wrap 5 and do the rubber packing 7 of support with highly-flexible low-carbon (LC) zinc-coated wire, one of them is located in the middle of the three beams master core 1, and all the other are located at outside the described three beams master core conductor.
The insulating outer layer isolation 6 of described main fibre core is polyester film.
Claims (2)
1. automobile-used drag cable in sky, it comprises the three beams master core, every bundle master core contains stranded conductor, conductor is surrounded by separator, insulating barrier and insulating outer layer isolation outward successively, three beams master core outer wrapping core wrap and oversheath, it is characterized in that, also be provided with in described every bundle master core and the stranded opposite aramid fiber of direction of lay and conductor; Also be provided with one group in the described core wrap and do the rubber packing of support with highly-flexible low-carbon (LC) zinc-coated wire, one of them is located in the middle of the three beams master core conductor, and all the other are located at outside the described three beams master core conductor.
2. described day automobile-used drag cable according to claim 1 is characterized in that the insulating outer layer isolation of described main fibre core is outer to be polyester film.
