This type of cable is used in low voltage only and because it is mentioned by the P.V.C material
It has a refractive voltage up to 1 kV only so it is used in low voltage only.
From: -P.V.C The low-voltage cable is composed of an insulated beam
Mosul
It is colored in red, yellow, blue, white, or black
(Filler) + bond or compound Vazat.
