Advanced fire-rated cables from Helukabel

®

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.
