PVC Insulated Electrical FR HR Insulated Wires To add to the existing range of electrical wires, K. Flex introduces - Flame Retardant PVC insulated electrical wires, which offers added safety. Each wire is manufactured using 99.97% pure, electrolytic grade, bright annealed bare copper with more than 100% conductivity better purity & conductivity. of copper ensures greater saving of electrical energy and thus helps to reduce electricity bills. The conductor is made of multiple strands of finely drawn copper wires thereby offering greater flexibility which makes these wires ideal for conduit wiring. The wires are insulated with a Flame Retardant (FR) PVC compound which helps in restricting spread of fire even at very high temperatures. All wires are subjected to high voltage spark testing to make sure that there are no weak spots in the insulation. This FR PVC compound has a high oxygen and temperature index. These wires meet the requirements of IS 694 : 1990. They additionally offer Flame Retardant (FR) properties. This means extra protection against electrical shock, short circuit and fires.
