In this article from Arian Abhar wire and cable, we have explained about two-core power cable with copper and aluminum conductors. Stay with us.
Cables are an integral part of the electricity industry, and without them, it would be impossible to transmit electricity, whether between two small points or long distances.
For electricity transmission, different types of cables have been produced, which are used in electricity production and distribution projects or residential, commercial and industrial buildings, depending on the place of use and the type of use.
One of these types of cables is the power cable, which is used to transmit electricity with high voltage. The power cable has different types in terms of the number of strands and is divided into single strand and multi strand samples. Multi-stranded cable also has different categories of two, three, three and a half, four and five strands.
In this note, we will get acquainted with one of the types of power cables, i.e. two-core power cable with copper and aluminum conductors, and we will compare this type of cable with single-core and multi-core cables.
To get this information, it is enough to follow the website of Arian Cable and Wire Company until the end of this note.
Getting to know the two-core power cable
As it can be seen from the previous explanations, the power cable is basically a cable that is used to supply the consumer’s main electricity. The two-strand power cable means that these cables, unlike single-strand cables, have two insulated conductors, which can be made of copper or aluminum.
Two-core power cable with copper conductor and insulation can be used inside or outside the building or even underground. For this reason, these cables are also known as “earth cables”.
Two-strand power cable structure
A two-core power cable consists of 2 cores made of copper or aluminum conductors. These two cores, which are known as phase and zero, are located next to each other and give the cable a flat or oval shape.
A copper conductor is more conductive than an aluminum conductor, as aluminum is approximately 60% more conductive than copper. However, the weight of two-core power cable with aluminum conductor is less. For this reason, it is necessary to choose the type you need in consultation with an expert before buying a cable.
Each core in a two-core power cable is individually surrounded by a colored PVC insulation for easy identification and isolation of the wires.
Both cores are then surrounded by a final outer layer that is again made of PVC. This outer layer is known as the sheath or jacket.
What are the uses of power cables with copper conductor and double strand insulation?
The main applications of two-core power cable with copper and aluminum conductors are in single-phase systems that do not require earthing. Also, this model of cables is also used in DC (direct current) applications.
It should be remembered that if you want to use single-phase electricity with earth, you should choose a three-wire cable instead of a two-wire one.
Note: Use all single-core and multi-core power cables only in places where there is no possibility of mechanical impact.
Study suggestion: three-wire power cable
Comparison of double-stranded and single-stranded power cable
In short, the most important difference between double-stranded and single-stranded power cables is the difference in the amount of electrical resistance. The resistance of double-stranded cables is higher than that of single-stranded cables due to their larger cross-sectional area. This cross-sectional area is mostly created by the gaps between the strings.
In addition, the production cost of double-stranded cables is higher than single-stranded cables, and these cables perform better at high frequencies compared to their single-stranded brothers. The reason for this is a phenomenon called “skin effect” that causes energy loss in the cable.
Buying two-core power cable with copper and aluminum conductor

Conclusion:
In this note, we briefly got acquainted with one of the types of multi-core power cables, i.e. the two-core power cable, and we got to know its structure and applications. We hope this article has helped you get the information you need.
