bare copper conductor in cases such as earthing (use as an earth wire to protect against electric shock ) is used.
In this article, I will answer a question that the customers of Thaghafi Trading Group often ask about wires and cables, and sometimes it makes us think that wires and cables are the same.
I will mention the first two wrong answers:
1- A wire is a single strand and a cable is multi-strand × ×
2- Each conductor is of a lower size than a wire and higher sizes of a cable × ×
I will write you the correct and simple definition of this question:
Copper wire or copper conductor without coating
Wire or wire -wire -wire
To protect the conductor from leakage, electric shock, physical shielding and other things, the use of layer It is called insulation (pvc) to prevent the mentioned things.
which this wire structure is named.
Cable and cable width and semiconductor -aluminum and aluminum
Now, if we need layers such as shield, armor, screen on the wire, or if we want to put several wires on top of each other (and fill the empty space with filler), we will need another layer. which is called the outer sheet (external sheath) or jacket and cover, which is placed on the mentioned layers or several wires and makes a coherent structure.
The final cover can be made of pvc or xlpe OK
