Abstract
The utility model discloses a copper-clad aluminum conductor extruded insulation power cable with a rated voltage of 1 kV. The cable comprises a protection layer at the outer side, wherein an armor layer and a belting layer are sequentially arranged at the inner side of the protection layer, four groups of conducting wires with insulating layers are arranged in the belting layer, each group of conducting wires is composed a plurality of copper-clad aluminum conducting wires of a pressing structure, the section of each group of conducting wires is fan-shaped, and the section of each copper-clad aluminum conducting wire is in an irregular shape. The conducting wires in the cable disclosed by the utility model have compact structures, no gap exists between the conducting wires, and copper is replaced with aluminum, so that the copper consumption is small and the cost is low.
Description
Technical field
The utility model relates to a kind of insulated power cable, particularly a kind of rated voltage 1kV copper clad aluminum conductor extruded insulation power cable.
Background technology
The structure of existing rated voltage 1kV copper conductor extruded insulation power cable is that outermost layer is a sheath, is followed successively by armour, belting layer in the sheath inboard, and four groups of leads are arranged in the belting layer, and every group of lead formed stranded conductor by many pure copper wires.Be provided with the limit filler in the gap between belting layer and every group of lead, in the middle of four groups of leads, be provided with inner stuffing.Promptly there is the space in the power cable of this structure owing to form certain clearance mutually between every group of inner each root lead of copper conductor, takies certain space, and inner lead is copper material, need to consume a large amount of copper materials, the overall weight of cable is big, the manufacturing cost height.
Summary of the invention
The purpose of this utility model provides tight between inner each the conductor structure compactness of a kind of cable, each root lead, with aluminium for copper, amount of copper consuming is little, cost is low rated voltage 1kV copper clad aluminum conductor extruded insulation power cable, overcome the deficiencies in the prior art.
Rated voltage 1kV copper clad aluminum conductor extruded insulation power cable of the present utility model, the sheath that comprises the outside, the sheath inboard is followed successively by armour, belting layer, the lead that four groups of tape insulation layers are arranged in belting layer, described every group of lead is made of many copper cladding aluminum conductors that press structure, and every group of conductor cross-section is fan shape.
Rated voltage 1kV copper clad aluminum conductor extruded insulation power cable of the present utility model, the fan-shaped radius included angle A of the sector crosssection of described every group of lead are 89 °-90 °.
Rated voltage 1kV copper clad aluminum conductor extruded insulation power cable of the present utility model, described every group of lead has 19, and the centre is a heart yearn, is distributed with 6 middle layer conductors in the periphery of heart yearn, is distributed with 12 boundary layer leads in the periphery of middle layer conductor.
Rated voltage 1kV copper clad aluminum conductor extruded insulation power cable of the present utility model compared with prior art at the D.C. resistance that guarantees conductor, guarantees the electrical transmission performance, D.C. resistance (R
20) under the situation identical, change into the fan-shaped conductor that presses structure by the circular stranded conductor of prior art with the D.C. resistance of equal specification pure cu conductor, eliminate space between the adjacent copper-clad aluminum conductor, reduced overall dimension, the proportion of copper is 8.89g/cm
3, and after having adopted the wire rod model to be the copper clad aluminum conductor of CCA-15A, its material proportion is 3.63g/cm
3, the actual cross-section of conductor is 133.8mm
2, the copper layer weight of single conductor accounts for 35.7% of conductor single line weight, and conductor material consumption has obvious decline after testing.Existing YJV4 * 95 copper cables and YJV (TBL) 4 * 95 copper clad aluminum conductor cable conductor consumption contrast tables are as follows:
Description of drawings
Fig. 1 is the cross-section of cable structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: cable of the present utility model comprises the sheath 9 in the outside, and sheath 9 inboards are followed successively by armour 8, belting layer 7, and the lead (conductor) of four groups of tape insulation layers 3 is arranged in belting layer 7.
Every group of lead formed by many copper-clad aluminum conductors, and every group of lead all adopts impacted process to press, and forms many copper cladding aluminum conductors that press structure.Tight between the adjacent copper cladding aluminum conductor forms dense state.And every group of conductor cross-section be fan shape, and the cross section of every copper cladding aluminum conductor is abnormity behind impacted process.
The fan-shaped radius included angle A of the sector crosssection of every group of lead is 89 °-90 °.
Every group of lead has 19 copper cladding aluminum conductors to constitute, and is heart yearn 5 in the middle of it, is distributed with 6 middle layer conductors 6 in the periphery of heart yearn 5, is distributed with 12 boundary layer leads 4 in the periphery of middle layer conductor 6, from inside to outside forms the structure of 1+6+12.
Tight between inner each the conductor structure compactness of cable of the present utility model, each root lead, with aluminium for copper, amount of copper consuming is little, cost is low.
