Hilay Cables
Fasco Hilay Cables
Wires With FR Insulation Are Flame Retardant. These Wires Are Used Where Safety ‘s Of Prime Concern.These Wires Are Superior Than Ordinary Pvc Wires In Every Respect. This Insulation Does Not Burn Easily. It Does Not Melt & Drip To Spread Fire.
This specially formulated insualtion compound is high temprating of 105c for short duration upto 125c.
How FR Insulated Wires Are Better Than Simple Pvc Wires
- Better Fire Retardant Properties.
- Self – Extinguishing
- Emit Leser Amount Of Fumes
- Enviornment Friendly
- Provides Better Safety
- FR PVC Can Bear More Temp
FR PROPERTIES
| Properties | Test Method | Value |
| Limited Oxygen Index | ASTM – D2863 | Minimum 29% |
| Temperature Index | ASTM – D2863 | Minimum 250°C |
FIRE-EFFECT & SMOKE EMISSION COMPARISON TEST
| Ordinary PVC Wires Prone to catch tiame, burns with lot of black smoke and toxic gases. | FR Wires Delays fire action, burns slowly with less smoke |
Conductor
The conductor of a cable is like the heart of the human being. The function of the conductor is to carry current like the heart circulates blood in the body. If the blood circulation is irregular & improper, it may cause various diseases in the body, similarly, if the copper conductor is not good may be due to reasons of impurity of copper, hardiness of copper, improper bunching (i.e. loose, longer lay length and air gap), the current carrying capacity will reduce and will have inductive losses. This forces us to use higher size of cables (conductor) for safety purpose, and thus we end up paying more for less output.
The conductor is known as hilay thin strands of electrolytic copper are multi-drawn simultaneously for uniformity of resistance, dimension, flexibility ; drawn strands are collected and unit-laid in high precision machines and further compacted, thus inheriting the following properties, which are absent in ordinary bunch conductor cable.
