ZHFR
ZHFR is processed using Zero Halogen Flame Retardant compound (ZHFR). The insulation is of superior quality, 100% PVC free and eco-friendly. In case of a fire situation ZHFR does not emit toxic or poisonous fumes, which enables safe evacuation. These wires are best suited for wiring in hospitals, hotels, business establishments and high rise buildings where fire can be determined. So give yourself the promise of security and best quality. Get MEHAL ZHFR and safeguard your home for life.

Technical Data
-
Voltage Grade : Up to and including 1100 V.
-
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.
-
Insulation Conformity : IEC 60332-1&3, IEC 60754-1&2
-
Insulation : The bunched conductors are insulated with specially formulated grade of Halogen Free Retardant compound is used. The insulation does not melt or drop in case of fire. The smoke emitted is non toxic and minimal. The victim trapped in the fire do not suffocate & evacuation is convenient.
-
Colors : Red, Yellow, Blue, Black, Green & Grey
-
Marking : Printed with marking of “MEHAL ZHFR”
-
Packing : 90 mtr. Coil is packed in protective cartons
