Abstract
The utility model discloses a 450 750V and following outdoor with resistant pvc insulated cable that waits specifically belongs to cable technical field. The utility model discloses link to each other by the splice bar that polyvinyl chloride insulating sheath formed by two cable cores, the aluminium core conductor of cable core for wrapping up in polyvinyl chloride insulating sheath, its characterized in that: the nominal cross -sectional area of aluminium core conductor is 2.5mm2, 4mm2, 6mm2, 10mm2, 16mm2, 25mm2, 35mm2 or 50mm2, the polyvinyl chloride insulation thickness is 0.8m, 1.0m, 1.2m or 1.4m, the average value of polyvinyl chloride insulation thickness is not less than the nominal value, and its the thinnest department is not less than 90% of nominal value and subtracts 0.1mm. The utility model has the advantages that change the insulation core elder generation stranding of traditional cable, then extruded the design who synthesizes the oversheath, both reduced the former material consumption of cable, improved the flow that bears the weight of of under the condition of laying on an equal basis more core transposition stranding composite sheathed cable again, in addition the utility model is suitable for an exchange rated voltage 450750V and following, as the built on stilts fixed usefulness of laying in open air.
Description
Technical field
The utility model relates to field of cable technology, particularly a kind of 450/750V and the weather-proof polyvinyl chloride cable of following outdoor.
Background technology
Current energy-conserving and environment-protective are requirement and the trend of development of world economy, the line loss of the transmission of electric power energy occupies no small part, the ampacity improving cable not only can the raw material resources such as saving copper, aluminium, plastics, can reduce the loss in electric power transfer simultaneously.And the ampacity of the radiating effect that power cable is in operation on power cable plays vital impact, current conventional power cable are all the first strandings of insulated wire cores, and then extrude comprehensive oversheath, such structure plays the effect of restriction for the heat radiation of power cable, therefore greatly limit the ampacity of power cable, therefore urgently existing power cable structure is improved, to solve the heat dissipation problem that restriction power cable current-carrying capacity improves.
Utility model content
Technical problem to be solved in the utility model is to provide one and is beneficial to heat radiation, improves ampacity, the 450/750V of Loss reducing and the weather-proof polyvinyl chloride cable of following outdoor.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of 450/750V and the weather-proof polyvinyl chloride cable of following outdoor, the dowel formed by polyvinyl chloride insulation sheath by two cables core is connected, described cable core is the aluminium core conductor being wrapped with polyvinyl chloride insulation sheath, it is characterized in that: the nominal cross of described aluminium core conductor is 2.5mm
2, 4mm
2, 6mm
2, 10mm
2, 16mm
2, 25mm
2, 35mm
2or 50mm
2, described polyvinyl chloride insulation thickness is 0.8m, 1.0m, 1.2m or 1.4m, and the mean value of described polyvinyl chloride insulation thickness is not less than nominal value, and its thinnest part is not less than 90% of nominal value and deducts 0.1mm.
The beneficial effect adopting technique scheme to produce is: the utility model has the advantages that the first stranding of the insulated wire cores changing traditional cable, then in the mentality of designing extruding comprehensive oversheath, by equipment special and mould insulated wire cores walked abreast and disposablely extrude into the flat cable with dowel, both the raw materials consumption of cable had been decreased, turn improve the bearer traffic compared with multicore twisted synthesizing cable composite-sheathed cable under equal laid condition, the utility model is applicable to ac rated voltage 450/750V and following in addition, fixedly lays use as outdoor aerial.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, aluminium core conductor; 2, dowel; 3, polyvinyl chloride insulation sheath.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1, the dowel that the utility model is formed by polyvinyl chloride insulation sheath by two cables core is connected, and described cable core is the aluminium core conductor being wrapped with polyvinyl chloride insulation sheath, it is characterized in that: the nominal cross of described aluminium core conductor is 2.5mm
2, 4mm
2, 6mm
2, 10mm
2, 16mm
2, 25mm
2, 35mm
2or 50mm
2, described polyvinyl chloride insulation thickness is 0.8m, 1.0m, 1.2m or 1.4m, and the mean value of described polyvinyl chloride insulation thickness is not less than nominal value, and its thinnest part is not less than 90% of nominal value and deducts 0.1mm.
Product technology parameter is as follows:
