LSHF INSULATED CONDUIT WIRE (H07Z-R)-6491B CABLE

In power stations, hospitals, theatres, hotels and other large public buildings. The Low Smoke Zero Halogen HO7Z-R cable is ideal for use in applications where fire, smoke, emissions, and toxic fumes would create a potential
threat.
The nature of organic material used in the cable manufacture of cables and possible installation conditions in areas of the fire risk can lead to a situation, where cables may contribute to the spread of fire, emission of smoke and release of combustion products injurious to equipment and human health.

LSHF cables use special formulation based on non-halogenated polymers to restrict the generation of smoke as much as possible. Materials are carefully selected, and the compounds carefully designed to ensure the best performance of the external sheaths, which are directly exposed to fire.

The compounds used in the manufacture of LSHF cables do not contain any smoke-generating constituents, particularly halogens (fluorine, chlorine, bromine) and thus do not emit halogenated acids emitted by standard materials such as PVC, when exposed to flames, which minimizes the total cost of damage caused by fire. Furthermore, the rate at which this low level of smoke is released is much slower than that of PVC or similar halogenated
polymers.

LSHF Cables have controlled limits on smoke evolution, when assessed by burning samples of cables in a 3 meter cube smoke chamber as per IEC 61034. Generally these cables combine the properties of low corrosive gas emission and low toxic gas emission as they are essentially halogen free when assessed by IEC 60754-1 and IEC 60754-2.
