Fire resistant flame retardant cable sheaths are design to resist combustion and limit the propagation of flames.it is suitable for power transmission and distribution line with rated voltage 300/500V, 450/750V, 0.6/1kV.Due to relative low cost, fire retardant cables are widely used as fire survival cables.Fire resistant cables are often used to maintain circuit integrity of those vital life safety systems such as fire alarm and suppression services.
Fire Rated Cables:
1.Flame Retardant - designed for use in fire situations where the spread of flames along a cable route needs to be retarded.
2.Fire Resistant (FR) - cables are designed to maintain circuit integrity of those vital emergency services during the fire.
3.Low Smoke and Fume (LSF) - burns with very little smoke and fumes compared to standard PVC, fumes may contain halogens.
4.Low Smoke Zero Halogen (LSZH) cable - when burns there is very little smoke and fumes (compared to standard PVC the fumes contain no halogens.
5.Alternative names for LSZH - LSZO (Low Smoke Zero Halogen), 0HLS (Zero Halogen Low Smoke), LSHF (Low Smoke Halogen Free).
