The goal behind the introduction of Accord Fire Retardant Low Smoke (FRLSH)cables was to address these shortcomings. Pure copper conductors with severaldraws are used to make Accord FRLSH wires. These cables are long-lasting becauseof the uniform resistance provided by the purity of copper. In the compoundingstage, PVC compound is added along with additives to boost its fire resistanceand reduce its smoke emissions. While Accord FRLSH wires have an oxygen index of 30% and a smoke density of less than 40%, normal PVC compounds have an oxygenindex of 25%. This helps with firefighting and rescue efforts and providesbetter visibility for the evacuation of victims who are stuck. FRLSH PVCinsulated wire with a single core and several conventional copper conductors hasgood flame retardant, low smoke, and low halogen qualities.
