Abstract
The utility model relates to a high-voltage flat power cable with a rated voltage from 3kV to 35kV, and is applicable to a high-voltage cable from 3kV to 35kV. The high-voltage flat power cable comprises a plurality of cable cores, and is characterized in that the plurality of cable cores with shields are in parallel arrangement and connected with each other through sheaths which are extruded by one step and in parallel connection, and connecting bars formed by the sheaths are connected between the cable cores. The high-voltage flat power cable has the advantages that insulated cores are connected by the parallelly connected sheaths with the connecting bars, and installation and laying are convenient; the number of the sheaths and the connecting bars are changed according to the core number of the insulated cores, and the laying shape can be adjusted conveniently; workload that multiple laying is needed for a plurality of single core cables is reduced; compared with an usual stranding composite-sheathed cable, the high-voltage flat power cable is advantaged by simple structure, economical material and relatively low cost and price; and compared with the usual stranding composite-sheathed cable, heat dissipation effect of the high-voltage flat power cable is good, and carrying capacity of the high-voltage flat power cable is relatively increased by 20%-50% under the same laying condition.
Description
Technical field
The utility model relates to a kind of rated voltage 3kV to 35kV high pressure Flat power cable, belongs to the cable technology field.
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 has occupied no small part, but the ampacity of raising cable is the raw material resourceses such as saving copper, aluminium, plastics not only, can reduce the loss in electric power transfer simultaneously.And the radiating effect that power cable is in operation plays vital impact to the ampacity of power cable, the conventional electric power cable is all the first strandings of insulated wire cores at present, and then extrude comprehensive oversheath, such structure plays the effect of restriction for the heat radiation of power cable, therefore greatly limited the ampacity of power cable, therefore demand existing power cable structure is improved the heat dissipation problem that improves to solve the restriction power cable current-carrying capacity urgently.
Summary of the invention
The purpose of this utility model is that solution power cable of the prior art is all the first strandings of insulated wire cores, and then extrude the existing problem that is unfavorable for cable heat radiation of comprehensive oversheath, a kind of ampacity that can accelerate the cable heat radiation and then improve cable is provided, reduces the Flat power cable of the loss of electric energy in the cable running.The utility model design 1, rated voltage 3kV are to 35kV high pressure Flat power cable, comprise some cables core, it is characterized in that: some cables core are arranged in parallel and are linked together by the disposable parallel connected sheath of extruding, and the dowel that is formed by sheath between each cable core is connected.The conductor of described cable core is solid conductor or stranded conductor, and conductive material adopts aluminum steel, copper cash or aluminium alloy wire.Described cable core is by being comprised of conductor, conductor screen, insulating barrier, insulation shielding, metallic shield according to this outside interior.Conductor screen is extruded and is formed by semiconductive shieldin material, insulation is formed outward by polyvinyl chloride, polyethylene or the crosslinked polyetylene insulated conductor screen that is extruded in of high insulating property, insulation shielding is extruded and is formed by semiconductive shieldin material, metallic shield by copper strips wrapped form or copper wire bundle around forming.Cable core quantity can be 2 cores, 3 cores, 4 cores or as the combining form of 3+1 core by the big or small cable core of difference.Described sheath is pvc sheathing compound, polyethylene sheath material or weather resisteant polyethylene sheath material.
The utility model has the advantages that the first stranding of the insulated wire cores that has changed traditional cable, then extruding the mentality of designing of comprehensive oversheath, to thoroughly do away with the parallel disposable flat cable with dowel that extrudes into of edge core by equipment special and mould more, both reduced the raw materials consumption of cable, improved again under equal laid condition than the bearer traffic of multicore twisted synthesizing cable composite-sheathed cable.
Description of drawings
Accompanying drawing 1 is the structure cross sectional representation with three cables core of the present utility model, and Fig. 2 is the structure cross sectional representation (three major diameters, a minor diameter) with 3+1 root cable core of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Figure comprises that the cable core of some band shieldings that are comprised of conductor 1, conductor screen 2, insulation 3, insulation shielding 4, metallic shield 5 is arranged in parallel and linked together by the disposable parallel connected sheath 6 of extruding, and the dowel 7 that is formed by sheath between each cable core is connected.It is characterized in that: cable conductor is solid conductor or stranded conductor, and conductive material adopts aluminum steel, copper cash or aluminium alloy wire.It is characterized in that: cable core is comprised of cable conductor 1, conductor screen 2, insulation 3, insulation shielding 4 and metallic shield 5.It is characterized in that: conductor screen is extruded and is formed by semiconductive shieldin material, insulation is formed outward by polyvinyl chloride, polyethylene or the crosslinked polyetylene insulated conductor screen that is extruded in of high insulating property, insulation shielding is extruded and is formed by semiconductive shieldin material, metallic shield by copper strips wrapped form or copper wire bundle around forming.It is characterized in that: cable core quantity can be 2 cores, 3 cores, 4 cores or the 3+1 core combining form by the big or small cable core of difference.It is characterized in that: described sheath is pvc sheathing compound, polyethylene sheath material or weather resisteant polyethylene sheath material.Extrude and form middle whole oversheath with dowel by frock and mould by many eradications edge core parallel arranged is disposable while extruding.
Main feature of the present utility model is that this product has adopted and makes the multi-cable core disposable parallel connected sheath of extruding that is arranged in parallel; Each cable core is by the parallel connection of dowel, and mounting and installation is convenient; The sheath dowel that has varying number according to the different core numbers of insulated wire cores, also be convenient to adjust and lay shape; Reduced the workload that adopts many single-core cables repeatedly to lay; The more common twisted synthesizing cable composite-sheathed cable of cable is simple in structure, economical with materials, the advantage of cost and relative low price; Compare with common twisted synthesizing cable composite-sheathed cable, the good heat dissipation effect of cable, under identical laid condition, current-carrying capacity of cable is than the corresponding increase of twisted synthesizing cable cable 20%-50%.
