Essentially, the compound used in manufacturing cables meeting the above specification reduces the amount of dangerous/poisonous gases in case of fire. shall emit a certain amount of toxic gases (< 17% by weight), LSHF Cables when burnt give off very little smoke, grey in colour and little or no hydrogen chloride. So in a high risk populated area where escape is limited LHSF cables … Almost all modern cables are required to pass some type of flame test. This is achieved as these cables burn slowly and do not propagate fire. It is important to separate the fire performance of wire and cable from the LSZH label. This is done by measuring pH-value and conductivity. LSZH installation can be used in the below applications but are not limited to the below mentions: What is the difference between LSF and LSZH cables? Liquid Tight Halogen Free Flexible Conduit, Highbay Lighting/ Warehouse Lighting/ Factory Lighting. The right lighting can make a great difference … Both are different cables. Also, it makes firefighting operations easier as the fire fighters can easily identify and reach the source of fire.
