Fire Retardant low smoke Wires & Cables have taken over other conventional wires & cables as fire is creating havoc everywhere in our lives.
Awareness for safety against fire has increased with bitter experience where in individuals & the nation have suffered great losses.
Our Principal company developed & launched FRLS wires & cables to minimize the loss of human lives & property during fire hazards.
In case of FRLS wires the insulation & in case of LT 1.1KV grade cables, the outer sheath is specially formulated flame retardant low smoke type PVC Compound having high oxygen & temp. index, with reduced emission of halogen & smoke.
Properties of FRLS PVC Compound
| Test | Governing Specn. | Test Significance | Result | |
| Conventional Wire | FRLS Wire | |||
| Oxygen Index Test | ASTM D-2863 | Determines the Oxygen concentration in the oxygen/nitrogen mix. in which material burns at room temp. | 23< | >29 |
| Temp. Index Test | ASTM D-2863 & BICC Handbook | Determines the temp. at which the Oxygen Index of material becomes 21. | <1600C | >2500C |
| Smoke Density Test | ASTM D-2843 | Indicates the extent to which material is likely to smoke under conditions to active burning & decomposition in the presence of flame | >80% | <60% |
| Acid Gas Generation Test | IEC 754 – 1 | Determines the amount of holegan Acid gas (other than hydro fluoric acid) evolved during combustion of compound. | >40% (By wt.) | <20% (By wt.) |
