L.C. Premium Cables for the first time brought FRLS - Flame Retardant Low Smoke electrical wires in India. L.C.Premium, FRLS is manufactured by using electrolytic grade copper to ensure superior conductivity. Insulated with extra thick FRLS Insulating compound, L.C.Premium FRLS has special flame retardant and low smoke emitting properties.
L.C. Premium Cables is the only Company in India providing insulated electrical wires that offer FRLS properties maintaining all electrical properties in an insulated wire. During a fire, ordinary PVC insulated wires give out thick, black smoke and toxic fumes of hydrochloric acid gas. This impairs visibility and hampers rescue operations. L.C.Premium FRLS on the contrary, emits very little smoke, toxic gases and also retards the spread of gas. It is thus ideal for concealed and conduit wiring in multi-storeyed buildings such as hotels, banks, hospitals, commercial & residential complexes, etc.
Conductor: The condtictors, drawn from bright electrolytic grade copper, are annealed and bunched together.
Insulation: Bunched conductors are insulated with specially formulate" Flame Retardant Low Smoke Compound. During a fire situation, the FRLS compound restricts the spread offlame. The smoke emission is also minimal.
L.C.Premium FRLS goes through rigorious tests to ensure the highest standards of quality. It is also backed by the ISI mark approval.
