Flexible & Solid Wires

Flexible & Solid Wires

The structure of this type of wire consists of a conductor made of copper and a layer of PVC insulation on the conductor.
The standards used to produce these wires in Iran are the ISIRI 607-3 standard, which of course is the international equivalent of IEC 60227-3.
These wires are commonly used for home use, lighting systems and control panels.
The following table shows the characteristics of the above abbreviations:
