POWER-FLEX® Single core and Multicore cables are manufactured using Electrolytic Grade 99.97% purity copper with more than 100% conductivity. The high purity & conductivity ensures superior working of the wires throughout their life. The conductor is drawn from bright electrolytic grade copper and annealed copper are bunched tightly together in heavy duty high speed bunchers in circular construction to get perfect concentric shape without any loose strands.
The bunched conductors are insulated with specially formulated PVC compounds with additional FR properties whose values exceed the specifications laid down by the Bureau of Indian standards. The compound is resistant to moisture, oil, alkali and grease and has high insulation and dielectric values. The FR properties with high Oxygen and temperature index help in restricting propagation of fire at high temperatures. The insulation is carried out on state-of-the-art high speed double extrusion lines with self centering cross head. Automatic diameter controllers ensures precision centering and perfect concentric insulation. The skin insulation determines the colour identification while the inner layer is pure insulation free from any impurities. The high quality tooling ensures smooth insulation.
Online spark testers ensure fail proof high voltage test by employing non destructive form of testing at six times the rated voltage ensuring consistent application of voltage throughout the length of the cable.
