FR Cable - upto 1100V
USP
- Special Heat Resistant and Flame Retardant.
- Higher Current Rating.
- Higher Temperature Rating.
APPLICATIONS
Suitable for use in conduit and for fixed protected insulation particularly sultable for wiring in fire and explosion prone areas, chemical factories, densely wired areas, public buildings, schools, hospitals, commercial complexes, theaters etc.
SPECIFICATIONS
Generally conforms to, IS 694
CONDUCTOR
Many thin strands of Electrolytic Copper are fine – drawn simultaneously for uniformity of Resistance, Dimension and Flexibility. The drawn strands are twisted in high precision machines and compacted. This not only imparts circularity to the bunched conductor but also prevents the tendency of the strands to separate and exert internal pressure on the insulation when the cable is bent during installation and usage.
INSULATION
Specially formulated high temperature grade of Flame Retardant compound to restrict the spread of flames in fire situation. The smoke emitted by the burning cable is less compared to traditional cables. This ensures improved visibility for evacuation of trapped victims and facilitates fire fighting operation.
