APPLICATION
Wiring in all installations where fire safety is of utmost importance like schools, theaters, commercial complexes, apartments, high rise buildings, laboratories, etc.
TECHNICAL DATA
Voltage Grade :
Up to and including 1100V
Conductor :
Thin strands of electrolytic copper are multi-drawn
for uniformity of resistance, dimension and flexibility.
The drawn strands are uni-laid with high precision and compacted.
Thus forming a perfectly circular conductor which enables reduction
in overall diameter for space saving in high density wiring.
Conductor Speciality :
The strands do not get cut when stripping the insulation. The conductor offers perfect contact at pins, terminals and sockets. Thus, eliminating spot heating and sparking.
Insulation :
Specially formulated grade of Heat Resistant & flame retardant compound is used. The insulation does not burn readily. It does not melt and drip, non-toxic.
Insulation Confirmity :
IS 5831, Type - HR 105°C & FR - 90°C
Marking :
The cables are printed with marking of “VIHAN ONELAY (UNILAY CONDUCTOR) HR - FR” upto 4 Sq. mm
Packing :
90 mtr. coils packed in “STACKPAK” with protective Cartons.
PROPERTIES
Limited Oxygen Index as per ASTM - D 2863 - >32%
Limited Temperature Index as per ASTM - D 2863 - > 250°C
Smoke Density (Light Absorption) as per ASTM - D 2843 - < 10%
