Copper core and AAC conductor cost comparison


The AAC Conductor chemical composition, it is easy to see, the above AAC Conductor elements accounted for 90 percent, is the main component of the AAC Conductor, a relatively small proportion of other trace elements, little difference in the cost of computing Since at present there are no standards regarding AAC Conductor, therefore, in this paper, only the same electrical properties of copper cable and AAC Conductor cost analysis.


In copper cables YJV3 × 95 + 2 × 50, for example, when AAC Conductor cross section is 1.5 times the copper cable, the same as its electrical properties, namely copper cables YJV3 × 95 + 2 × 50 and AAC Conductor YJLV3 × 150 + 2 × 70 identical electrical properties (voltage levels are: 0.6 / 1kV), a lot of people have this concern, worry about the cross-section of AAC Conductor to 1.5 times the copper cable, cable diameter will increase a lot, thus increasing cable insulation material, wrapping, filling auxiliary costs, sheathing materials, and also fears increased installation costs. 


In fact, this concern is entirely superfluous, because the use of a special squeeze process, AAC Conductor conductor pressed coefficient of 0.90 or more, the slight increase in AAC Conductor in diameter under the premise, can fully meet the conductivity copper core conducting capacity of the cable, and will not increase the number of auxiliary costs.


The raw material cost of AAC Conductor copper cable of 19.26%, according to industry insiders, AAC Conductor and aluminum cable production technology and production process are basically the same, while the proportion in the total amount of trace elements in relatively little AAC Conductor raw material costs are slightly higher than aluminum cable, about 20% -25% of copper cables.
