Flame Retardant (FR) vs Flame Retardant Low Smoke(FLRS)
Flame retardant cables are designed to resist
the spread of fire into a new area. Fire resistant cables are designed to
maintain circuit integrity and continue to work for a specified period of time
under defined conditions. Highly engineered polymers developed after years of
research have produced a new generation of cable that has excellent electrical
and mechanical...Importance of Flame Retardant:
Copper wires are
always the best:
Good quality cables that are fire resistant have high
tensile strength and are extremely resistant to high temperatures. Copper wires
are generally used for house wiring and you must ensure that high quality
copper wires are used. If there are any impurities in the copper, there is a
high probability of short circuits caused by overheating.
Quality cables made
to combat fire:
Fire is a major cause for the loss of human lives and
property thus; fire safety is a major focus area for most good brands of wires
and cables to focus on. To understand this better, you must learn a little
about wires and cables. Cables are insulated with organic polymeric compounds.
These compounds are halogenated products containing Chlorine, Bromine and
Fluorine. When the wires are exposed to heat, the insulation starts to
decompose, releasing dense toxic smoke which causes asphyxia and impairs
vision. To address this issue, cable manufacturers have introduced different
varieties of fire resistant cables. They are FR (Fire Retardant) cables, Fire
Retardant Low Smoke (FRLS) cables, Low Smoke Zero Halogen (LSZH) cables and
Fire Survival (FS) cables. It is always advisable to use these types of wires
in the home.
FRLS Cable means Flame Retardant Low
Smoke. These cables are fire resistant which are used at the
locations that are more prone to fire. Flame Retardant Low Smoke PVC compound
which is present in the cable, makes sure the release of low smoke compared to
other wires with PVC coating. FRLS cables should be used in places with major
possibilities of fire accidents namely: power plants, industrial complexes,
hotels and places of public gathering.
Properties of FRLS:
1. The oxygen index of the cables should be more than 20%
2. Temperature index should be more than 250 degree C.
3. Cables should have the density of smoke that is less than
50% Max.
4. Hydrochloric acid advancement should be less than 17.5%
5. Should have a flammability test on done cable.
FRLS is the right
choice I believe .Ordinary PVC Continues to burn once fire is initiated without
external ignition .further , PVC smoke ( as its burns ) is supposed to be
toxic. FRLS PVC Compound which is
present in the cable, make sure the release of low smoke compared to other
wires with PVC Coating. These cables are less toxic in nature and emit low
amount of corrosive fumes.
These cables are meant to be used in places with high possibilities of
fire accidents namely industrial complexes, power plants, places of public
gathering and hotels. Therefore, the cables used in several electrical
installation should be resistant to fire.
They have a wide range of high
quality products from which you can choose. So, if you are looking for FRLS
Cable then look nowhere and contact the Kantibir Tradelink private limited.
