Through intensive research, certain compounds, which exhibit reduced
flame propagation, lower smoke and acid gas emission, have developed
by NICCO. The result of this research helped to incorporate these
properties in NICCO Paramite and Parapex Cables, through a new range
of cable designs, resulting in flame retardant cables with reduced
halogen evolution and smoke (FR-LS) cables. Typical FR-LS properties
exhibited by the outer sheaths of these cables are : |
- Minimum Oxygen Index : 29
- Temperature Index : 250°C
- Maximum Acid Gas Generation during fire : 20% by weight
- Maximum Smoke Density rating : 60%
- Flame Retardance - Withstands flame tests as per specifications
LEG 332 - 1, IEEE - 383, Swedish Standard SS - 4241475 - Class
f3 (for cable diameters up to 70 mm only).
Routine tests as specified in the relevant specification are earned
out on all the drum lengths of cable leaving the works. Type tests
and acceptance tests as specified are also carried out on random
samples, as and when necessary. Every lot of cable leaving NICCO
works undergoes the following tests at the final stages of manufacture:
Routine Tests : Conductor Resistance test High
voltage test
Type Test : All type tests as per relevant specifications,
viz : IS : 1554 (Part-l),
IS 1554 (Part-2), IEC 502, VDE, etc, are performed when desired
by clients.
