HOUSE WIRING CABLES – MULTISTRAND – FR & FLRS are made of Pure Electrolytic Grade, bright annealed bare copper with more than 100 % conductivity which makes it an excellent conductor of electricity, thus helps in saving energy. The conductors are insulated with a specially formulated Flame Retardant- FR grade PVC compound having high insulation resistance, oxygen, temperature index and dielectric strength which prevents leakage of electric current, it's flame retardant properties minimize the spread of fire which ensuring complete safety from shocks, short circuits and fires. Special Heat Resistant and Higher Current Rating Higher Temperature Rating Flame Retardant Low Smoke (FRLS) INSULATION. Many thin strands of Electrolytic Copper are fine-drawn simultaneously for uniformity of Resistance, Dimension and Flexibility. Particularly suitable for wiring in fire and explosion-prone areas, chemical factories, densely wired areas, public buildings, schools, hospitals, commercial complexes, theatres etc. LITMUS Multistrand Wires are available in RED, YELLOW, BLUE, BLACK, WHITE & GREEN COLOUR or any other colour as per customer requirement.
