Advanced fire-rated cables

September 2015 Fire & Safety, Products & Solutions

Advanced cables with the ability to maintain their integrity for up to two hours in fire condition have been introduced locally for fire alarm and emergency evacuation systems or wherever long-term electrical circuits are required under fire conditions.

The new generation cables are designed to self extinguish when exposed to flames and are halogen-free so they will not emit corrosive or toxic gasses under fire conditions. This makes them ideal for use in public areas to ensure essential electrical services are maintained in the event of an emergency.

The new Helufire PH30/120 cables from Helukabel expand the company’s range of function integrity products that include a large variety of security cables, as well as heat and fire resistant cables, enclosures, protection boxes, glands and accessories.

The range of Helufire cables are specially designed to withstand direct flames and heat of 850°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 from blasts caused by flammable substances exploding.

All Helufire cables are also manufactured in accordance with BS EN 50200:2006 which requires tests to be conducted to verify circuit integrity of cables exposed to fire at 850°C for the required duration as well as mechanical shock.

The cables are available in 2 or 4 core varieties from 1 mm to 2.5 mm cross sections to complement Helukabel’s 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 period of time with rating up to 3 hours. These are ideal for use in areas where function integrity is of the utmost importance such as hospitals, fire brigade, power stations, offshore plants, multi-storey buildings and public places.

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.
