Abstract
The utility model relates to a power cable, in particular to a power cable with a copper-clad aluminum conductor. The power cable comprises a plurality of strands of cables, wherein each cable comprises a conductor and an insulating layer wrapped outside the conductor; and the power cable is characterized in that a wrapping layer is filled between the cables respectively, wherein a sheath layer is covered outside the wrapping layer, and the conductor is formed by compounding an aluminum conductor and a copper conductor covered outside the aluminum conductor. The power cable has the advantages of small specific gravity, good transmission performance and the like and is particularly suitable to serve as the inner conductor of the radio-frequency coaxial cable; compared with the pure copper wire, the density of the power cable is about 40 percent of that of the pure copper wire, however, the transmission performance is superior to that of the pure copper wire, therefore, the power cable serves as the optimal inner conductor of the branch line for the radio-frequency coaxial cable; and since a copper layer is arranged on the surface of the copper-clad aluminum serving as the conductor of the power cable, the problems that the aluminum conductor is high in contact resistance and easy to oxidize during the using process are effectively solved.
Description
Technical field
The utility model relates to a kind of power cable, specifically a kind of copper clad aluminum conductor power cable.
Background technology
For electric wire manufacturing enterprise, copper accounts for 93% of its product total cost as its main raw material(s), and the price of copper and supply and demand variation all have very important effect to whole wires and cables industry.In recent years, lasting high-order operation along with the copper material price, each electric wire producer feels that cost pressure is increasing, and each producer is in order to reduce cost pressure, constantly improve product price, cost is finally born, by the consumer at the very high situation of copper conductor cable price, have a lot of consumers to be forced to the aluminium conductor cable of selecting price more cheap, but the aluminium conductor cable exist easy oxidation of conductor and the excessive problem of contact resistance.In view of above reason, press for a kind of consumer of allowing of invention and use not only safe and reliable but also cheap electric wire product.
Summary of the invention
The purpose of the present utility model is exactly the above-mentioned defective at existing cable, and a kind of copper clad aluminum conductor power cable is provided, and it has solved existing copper cable price height and the aluminium conductor cable exists easy oxidation of conductor and the excessive problem of contact resistance.
The technical solution of the utility model is achieved in that it comprises the multiply cable, cable comprises conductor and is wrapped in the outer insulating barrier of conductor, it is characterized in that: be filled with lapping layer between cable and the cable, lapping layer is wrapped with restrictive coating, and conductor is composited by the aluminum conductor copper conductor outer with being wrapped in aluminum conductor.
The utlity model has advantages such as proportion is little, transmission performance is good, be specially adapted to do the inner wire of radio frequency coaxial-cable, compare with pure copper wire, its density is fine copper about 40%, and transmission characteristic is better than pure copper wire, is optimal radio frequency coaxial-cable branch line inner wire.As the conductor of power cable, copper cover aluminum is because there is the copper layer on the surface, effectively solved the problem of the big and easy oxidation of aluminium conductor contact resistance in use.
