Aluminum and copper conductors are commonly used in the transport of energy. In this work, high-voltage cables occurring aluminum and copper conductors exposed to the same rated voltage values were analyzed. In order to obtain the same current carrying capacity for copper and aluminum conductors, the relationship between the cross-sections has been determined and then the most appropriate cross-sectional values for each conductor were identified. Three different cross-sectional values have been selected for each conductor type and the calculations for the cables were carried out by using the Cable Ampacity Calculations Program (CYMCAP) within the framework of the International Electrotechnical Commission (IEC) standards. The performance of the cables has been compared in terms of material losses, cable structures and the cable costs. It is seen from the simulation results that aluminum conductor cables have lower cost and higher electrical loses than the copper conductor cables.

Aynı anma gerilimlerine sahip farklı iletkenlerden oluşan yüksek gerilim kabloları üzerine bir araştırma

Öz

Alüminyum ve bakır, enerjinin taşınmasında yaygın olarak kullanılan iletkenlerdir. Bu çalışmada, aynı anma gerilim değerlerine maruz bırakılan alüminyum ve bakır iletkenlerden meydana gelen yüksek gerilim kabloları analiz edilmiştir. Bakır ve alüminyum iletkenlerinin aynı akım taşıma kapasitesine sahip olabilmesi için kesitleri arasındaki ilişki tespit edilerek her bir iletken için en uygun kesit değerleri tanımlanmıştır. Her iletken tipi için üç adet farklı kesit değeri seçilmiş ve kablolara ait hesaplamalar International Electrotechnical Commission (IEC) standartları çerçevesinde Cable Ampacity Calculations (CYMCAP) programı kullanılarak gerçekleştirilmiştir. Kabloların aynı şartlar altındaki performansları malzemeden kaynaklı kayıplar, kabloları oluşturan yapılar ve kablo maliyetleri açısından mukayese edilmiştir. Alüminyum iletkenli kabloların bakır iletkenli kablolara göre toplam elektriksel kayıpları daha fazla iken maliyetlerinin daha az olduğu görülmüştür.
