Advanced cables with the
ability to maintain their
integrity for up to two
hours in fire conditions
have been introduced
locally. The new genera-
tion cables are designed
to self extinguish when
exposed to flames and
are halogen-free so will
not emit corrosive or
toxic gases under fire
conditions.
The new He l u f i re
PH30/120 cables from
Helukabel expand the
company’s range of func-
tion integrity products
that include a large vari-
ety of security cables, as
well as heat and fire resis-
tant cables.
“The range of Helufire
c a b l e s i s s p e c i a l l y
designed to withstand
direct flames and heat
of 850 deg C for 30 minutes for the PH30 cables and two hours on the
PH120 cables. They are also shock resistant and able to withstand the
kind of forces that one might expect in a severe fire-related incident with
falling objects or even shock fromblasts caused by flammable substances
exploding,” says Doug Gunnewegh, MD of Helukabel South Africa.
“All Helufire cables are also manufactured in accordance with BS EN
50200:2006 which requires tests to be conducted to verify circuit integ-
rity of cables exposed to fire at 850 deg C for the required duration as well
as mechanical shock.”
Helufire cables are typically used in industrial complexes, power sta-
tions, communal establishments, mines and public places or wherever
the highest levels of function integrity are required to ensure the safety
of people, animals or property. The cables are suitable for fixed installa-
tions on or beneath plaster in dry and moist room applications. They are
also suitable to be run outdoors or underground in conduits that exclude
excessive water build-ups.
The cables are available in 2 or 4 core varieties from 1 mm to 2,5 mm
cross sections to complement Helukabel’s extensive range of function
integrity cabling products and accessories.
The line up of new products is further bolstered by security cables up
to 1 kV with the ability to withstand bare flames for extended periods of
time with ratings up to three hours.
In addition to cables, Helukabel also offers the full range of Spelsberg
function integrity junction boxes and enclosures. These are able to
match the cable products with different flame resistance ratings with the
additional benefit of having IP67 protection ratings for dust, water and
mechanical stress resistance.
