Abstract
The utility model relates to a capacity-expanded power cable used in a 0.6/1kv (or below) power transmission and distribution line. The expanded power cable is commonly used in an overhead or underground power transmission and distribution line, and comprises a conductor; the conductor is a compacted copper clad aluminum bimetallic composite conductor, on the outer surface of which a high-density crosslinked polythene insulating layer is arranged; and a plurality of compacted copper clad aluminum bimetallic composite conductors provided with high-density crosslinked polythene insulating layers are twisted together. The power cable can fully make use of the power transmission capacity of the conductors and saves material; the capacity-expanded power cable can effectively increase the conductivity of the conductors and the conductivity can reach that of a copper conductor with the same specification; and the application of the copper clad aluminum and the high-density crosslinked polythene insulating layers can greatly reduce the dead-weight of the cable, thereby reducing damage toe the cable by dead-weight.
Description
Technical field
The utility model relates to a kind of power cable that uses in 0.6/1kv and following electric power transmission line, relate in particular to the dilatation power cable of a kind of use in built on stilts or ground buried power transmission line.
Background technology
In 0.6/1kv and following electric power transmission line as Fig. 1, general employing copper core or aluminium core are conductor 3, polyvinyl chloride or crosslinked polyethylene are insulating barrier 4, and polypropylene mesh tearing film or polyvinyl chloride or polyethylene are packed layer 2, and polyvinyl chloride or polyethylene are the power cable of restrictive coating 1.This power cable, conductor 3 owing to kelvin effect, are not given full play to the electric conductivity of conductor when electric energy transmitting.In addition, conductor can play heat when electric energy transmitting, polyvinyl chloride or crosslinked polyetylene insulated layer 4 and restrictive coating 1 have big thermal resistance, have hindered conductor 3 distribute heats, make conductor not give full play to the ability of electric energy transmitting, also quickened the aging of insulating barrier 4 and restrictive coating 1.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of conductor electric energy transmitting ability of giving full play to save raw-material dilatation power cable.
For achieving the above object, the technical solution of the utility model is: described conductor is a compacting pressing copper cover aluminum bimetallic composite conductor, be provided with the crosslinked polyetylene insulated layer of one deck high density in compacting pressing copper cover aluminum bimetallic composite conductor outside, the many compacting pressing copper cover aluminum bimetallic composite conductors that have the crosslinked polyetylene insulated layer of high density twist together.
Described compacting pressing copper cover aluminum bimetallic composite conductor is meant and is aluminum metal in the middle of conductor, is the copper metal in the aluminum metal outside.
Be provided with the crosslinked polyetylene insulated layer of one deck high density in compacting pressing copper cover aluminum bimetallic composite conductor outside.
The utlity model has and to give full play to conductor electric energy transmitting ability and save raw-material advantage again, can effectively increase the conductive capability of conductor, and conductive capability can reach the conductive capability of the copper conductor of equal specification, the application of copper cover aluminum and high density crosslinked polyethylene has alleviated the cable deadweight greatly, has reduced owing to conduct oneself with dignity to the destruction of cable itself.
Description of drawings
Fig. 1 is the structural representation of existing power cable.
Fig. 2 is the structural representation of dilatation power cable of the present utility model.
Embodiment
As shown in Figure 2, the utility model comprises conductor, it is characterized in that: described conductor is a compacting pressing copper cover aluminum bimetallic composite conductor 6, is provided with the crosslinked polyetylene insulated layer 5 of one deck high density in compacting pressing copper cover aluminum bimetallic composite conductor 6 outsides.The many compacting pressing copper cover aluminum bimetallic composite conductors 6 that have the crosslinked polyetylene insulated layer 5 of high density twist together.
Described compacting pressing copper cover aluminum bimetallic composite conductor 6 is meant and is aluminum metal in the middle of conductor, is the copper metal in the aluminum metal outside.
Adopt compacting pressing copper cover aluminum bimetallic composite conductor 6, its copper aluminium component is selected the combarloy aluminum for use, has played dilatation, and conductive capability can reach the conductive capability of equal specification copper conductor.
The insulating barrier that the utility model is provided with in compacting pressing copper cover aluminum bimetallic composite conductor 6 outsides is the crosslinked polyetylene insulated layer 5 of high density, because the thermal resistance of high density crosslinked polyethylene approximately only has 1/3 of polyvinyl chloride, help the heat radiation of conductor, the conductive capability that this has just increased conductor has played the effect of dilatation; The crosslinked polyetylene insulated layer of high density 5 unites two into one insulating barrier and restrictive coating, has saved packing material between insulating barrier and the restrictive coating band, does not need to recharge material during stranding between the two.Help the heat radiation of cable like this, strengthened the conductive capability of cable, played the effect of dilatation.
