In all fire disasters, fire smoke, heat and toxic fumes are the main obstacles to safe evacuation of a building or area. A major contribution towards overcoming these hazards is the use of fire resistant and non-halogenated cables.
KEI Fire Resistant cable have been developed to maintain circuit integrity in a fire and to ensure maximum safe evacuation of personnel with no detrimental effects like toxic gases or smoke.
The Fire Resistant cable are constructed in the following typical format
Fire resistant | Flame retardant | Smoke emission | Acid gas emission | Oxygen index |
---|---|---|---|---|
IEC 60331; BS 6387: BS 8491: BS 8434/2 | IEC 60332- 1 & 3 | ASTM – D – 2843 | IEC 60754 | ASTM – D – 2863 |
The Fire Resistant cable may categorized by a letter symbol (e.g. A) or series of symbols (e.g. CWZ) in according to the requirements for fire resistance characteristics which they meet, the test temperature selected and the duration of the test for resistance to fire alone in according to BS 6387 as below
Resistance to fire alone | |||
---|---|---|---|
650 o C for 3 hours | 750 o C for 3 hours | 950 o C for 3 hours | 950 o C for 20 minutes (short duration) |
