The Growing Importance of Flame Retardance
until Recently Flame Retardance Was Never a Major Consideration When Choosing a Cable; Physical Performance and Reliability Always Took Precedence.
in the Recent Past, However, Growing Awareness of Fire Hazards Has Resulted in the Development of Flame Retardant Low Smoke Cables. Development, Fuelled By Devastation Fires in Power Stations and Elsewhere in the Country, Situations Where Cables Laid in Horizontal and Vertical Trays, Spread Extraneously Caused Fires.
Generally Outer, Sheathing Material is Made of Chlorinated Polymers like Pvc, Csp, Pcp, Etc., Polymers Which have Inherent Resistance to Flame Propagation. Yet, in the Event of a Fire, They Propagate Fire and Release Large Volumes Pf Dense Smoke, Toxic Gas and Hydrochloric Acid. Flame Retardant Cables Therefore Should Fulfill the Following Four Criteria:
Flame Retardance:
Ability to Restrict Flame Propagation
low Smoke Emission:
Smoke Emitted Should Not Obscure Visibility
Low Acid Gas Emission:
Gases Which When Combined with Water Produce High Corrosive Acids Which Damage Plant and Equipment.
Low Toxic Gas Emission:
Gases Less Injurious to Health.
