  UNIFY Cables Cable Range Cables Features
             
Rajdhani Zero Halogen Minimum Smoke Single Core Unsheathed Copper Cables
Having Compact Circular Unify Conductors
For Voltage up to 1100 Volts AC.
 
Conductor : Thin starands of Electrolytic Copper are multi-draw simultaneously for uniformity of Resistance, Dimension, Flexibility etc.The draw standers are are collected and uni-laid in high precision machines and further compacted. The perfectly circular conductor thus formed is intergral and compact. This enables reduction in overrall diameter for space saving in high density wiring. The strands do not get cut when stripping the insulation. The Conductor offers perfect Contact at pins, terminals and sockets. This eliminates spot heating and sparking.
 
Insulation : Specially formulated grade of Halogen Free Flame Retardant (HFFR) compound is used. The performance of the cable in fire situation is exceptionally good. The insulation does not burn readily. It does not melt and drip to spread fire. The smoke is negligible, transparent and non-toxic. The victims trapped in the fire do not suffer suffocation, can be evacuated with less difficulty, and the fire fighting is more convenient and effective. Unlike PVC, the smoke emitted is non corrosive. Thus the electronic printed circuit boards and hard disks are unaffected. Indeed, FIREWALL-HFFR wire fights fire even before you dial the Fire Brigade.

HFFR insulation is environment friendly and it saves human lives.
Colours : Red, Yellow, Blue, Black, Green
Packing : 90 mtrs. (Approx. 100 yards) coils packed in protective cartons; jumbo coils in special payout boxes also available to help reduce wastage at the time of installation.
