هادی آلومینیومی با مغزی فولادی ACSR/TW

Aluminum conductor with steel core or ACSR/TW, significantly reduces line losses. In continuation of the pre-introduction that we said earlier, in this situation, while the ratio of tension to the weight of the conductor remains constant, the use of a trapezoidal cross-section causes the diameter of the conductor to be compressed and reduced (10 to 15%). In this regard, by reducing the diameter of the conductor, the weight of wind and ice on it is reduced and it causes a reduction in the weight of the mast, a reduction in the wire Sag and an increase in the distance between the masts (Span) and saving the cost of running the line.

In the condition that the diameter of the normal ACSR conductor is the same as ACSR/TW, due to the compactness of the trapezoidal wire, the cross-sectional area of ​​aluminum increases by almost 20%, so the electrical resistance and line losses will be reduced by the same amount. In the conditions of keeping the line losses constant, a 20% increase in the cross-sectional area of ​​aluminum causes a 10% increase in the allowed current passing through the conductor. In this situation, the ratio of tension to the weight of the conductor decreases and the Sag of the wire increases.

Pooya Power company is able to produce this wire in different sizes and with different number of strands and according to the customer’s needs in the shortest possible time and with the highest quality.
