Why One Should Use LSF/LSZH Cables?
LSF/LSZH cables are desirable because it reduces the amount of smoke and poisonous gases generated, which significantly improves the chance of safe escape for the inhabitants.

Since the time fire got discovered, man has been making attempts to protect themselves from its harmful<br />
effects. We have always searched for preventive measures to make sure the damage is minimalized. Hence,<br />
<strong>LSF</strong>/<strong>LSZH</strong> cables were designed keeping in mind the safety of the public, which has become a major<br />
concern these days.<br />
We have seen several incidents in the recent past where fire has caused huge damage to people and<br />
property. The examples include the fire in The Address hotel near Burj Khalifa and Dubai Mall, Torch<br />
Tower Fire in Dubai Marina, and Grenfell Tower in London.<br />
Today, an average time to reach fatal condition is over 3 minutes, but before it was more than 15<br />
minutes. This change has come over because of the increasing use of plastics at home. None the less it is<br />
safe to say that smoke and effluent gases are relevant to saving human lives.<br />
<strong>LSZH</strong> installation can be used in the below applications but are not limited to the below mentions:<br />
Power cables<br />
Instrumentation cables<br />
High Voltage <strong>Cables</strong><br />
Control cables<br />
Building wires<br />
What is the difference between <strong>LSF</strong> and <strong>LSZH</strong> cables?<br />
Low Smoke Fume is another term used by some manufacturers for <strong>LSZH</strong> cables. A manufacturer can give<br />
the term as <strong>LSF</strong> as long as it emits negligible amount of toxic gases & less amount of smoke.<br />
<strong>Why</strong> <strong>LSF</strong>/<strong>LSZH</strong> cables different from normal PVC cable?<br />
<strong>LSF</strong>/<strong>LSZH</strong> cables are made of special material with flame retardant property which does not contain<br />
halogen. The low smoke zero halogen property makes cable environment protective.<br />
Is there a difference between Flame Retardant Low Smoke (FRLS) and Low Smoke Zero Halogen<br />
(<strong>LSF</strong>/<strong>LSZH</strong>) cables?<br />
Both are different cables. Low smoke emits clearer and thinner smoke when burning. This helps people<br />
to exit the building faster and safely. FRLS cables shall emit a certain amount of toxic gases (< 17% by<br />
weight), whereas Zero halogen cables do not emit any toxic gases as it does not contain halogens like<br />
fluorine, bromine and chlorine.<br />
Do <strong>LSF</strong>/<strong>LSZH</strong> cables cover the same range as the normal power & Instrumentation cables?<br />
The <strong>LSZH</strong> cables cover all the rated voltage ranging from 300/500V (instrumentation cable), 450/750V<br />
Wiring <strong>Cables</strong>, 600/1000V LV cables & MV cables up to 33kV.<br />
Does these <strong>LSF</strong>/<strong>LSZH</strong> cables and wires cost a lot?<br />
No, there is very small price difference, looking to the cost of project and longtime safety, it is negligible.
