RR Kabel wires are made up of strands of electrolytic copper that are fine drawn simultaneously for uniformity of Resistance, Dimension, and Flexibility. The drawn strands are twisted in high precision machines which imparts circularity to the conductor. RR Kabel electrical wires are specially formulated with lead free and flame retardant low smoke PVC insulation. The flame retardant low smoke (FRLS) property retards the propagation of flame without compromising safety. All cables are printed with generic marking 'FLAMEX FRLS'.
