FR (Flame Retardant)


Applications : Wiring in all installations where fire safety is more important. Schools, theaters, commercial complexes, air conditioned apartments, high rise buildings, fire alarms and emergency lighting circuits.
 
Specifications : Generally conforms to, IEC 60332-1 & 3, IEEE 383, IEC 60754-1 & 2, IS-8130, IS-694, IS-5831
 
Conductor : Thin strands of Electrolytic Copper are multi–drawn simultaneously for uniformity of Resistance, Dimension, and Flexibility . The drawn strands are bunched in high precision machines. A circular conductor is thus formed. The conductor is bunched in such a way that it reduces in overall diameter for space saving in high density wiring.
 
Insulation : Specially formulated grade of Flame Retardant (FR) compound is used. The performance of the cable in a fire situation is exceptionally good. The insulation does not burn readily. It does not melt and drip. The smoke is negligible, transparent, non toxic. The victims trapped in fire do not suffocate and this facilitates fire fighting operations. Unlike general purpose PVC, the smoke emitted is non-corrosive. Thus, the electronic printed circuit boards, hard disks and other sensitive electronic equipments are unaffected.
 
Marking : The cables are marked “ GEMINI CABLES-FR ( Size )1100V IS:694 CM/L NO-8381482”
 
Colours : Red, Yellow , Blue, Black, Green
