Cable bag has been marketed as an ideal solution to this problem.  This type of cable, also known
 by other names such as flat cable, flat spray cable and flat multi-strand cable, is an 
excellent option for hidden wiring under plaster, ceramic and other building coatings 
due to its flexibility and elegance. For a deeper understanding of this type of cable,
 we will examine its structure and technical specifications

Conductor material: Copper, as a conductive material with high electrical conductivity
 and suitable malleability, is considered the most common material for making the
 conductor of these types of cables.
Type of conductor: The conductor of the bag cable is of the Afshan type, which 
means that it consists of thin and flexible strands of copper wire. Due to its 
high flexibility, this type of conductor has the ability to bend and pass through 
narrow and complex paths.

Insulation:
Insulation material: Bag cable insulation is made of PVC (polyvinyl chloride) or other insulation 
such as PE (polyethylene). PVC is the most common insulating material for this type of cables
 due to its reasonable price, high resistance to moisture, acids and chemicals, as 
well as ease of production.

Insulation thickness: The insulation thickness of bag cable is determined according to the 
rated voltage of the cable and relevant standards. The thickness of the insulation should
 be such that it protects the conductor against applied voltage and external factors such 
as moisture and chemicals.
