Draka’s Firetuf cable series for the cabling of tunnel systems has grown with the launch of the new Firetuf OFC-LT-SWA fire resistant loose tube cable with steel wire armour.
As with all Firetuf cables, Firetuf OFC-LT-SWA has been designed for harsh environments and to ensure fail-safe management of operational systems in tunnels, underground railways and fire alarm systems. A steel wire armoured, refractory cable, Firetuf OFC-LT-SWA is ideal for heavy-duty applications due to its high mechanical strength and pulling tension, plus its resistance to even the most determined rodents.
The loose tube cable offers 90 minutes fire resistance thanks to its innovative design with double LSZH (Low Smoke Zero Halogen) sheathing in accordance with IEC standard 60331-25. The number of fibres per cable, from 12 to 144, is unique in the market.
The new Firetuf OFC-LT-SWA is the latest addition to Draka’s portfolio of loose tube cables, which includes non-metallic Firetuf OFC-LT-NM and corrugated steel tape armoured Firetuf OFC-LT-CST. With a maximum number of 144 fibres, all three cable types are unique in the market. All three cable types have been thoroughly tested and approved.
Draka also offers the Firetuf OFC-UT-NM (non-metallic) and Firetuf OFC-UT-CST (steel tape armoured) central tube cables, which have a fire resistance even longer than their loose tube variants – up to 120 minutes. Depending on the design, they are equipped with 2 to 24 fibres.
“The number of tunnels and subways are increasing from year to year in a bid to better manage our traffic infrastructure, but present challenges when it comes to emergency situations such as accidents or fires. Safety is, therefore, the central issue in the planning and construction of tunnels,” says Tayfun Eren, Product Manager at Draka, Prysmian Group. “The operational systems for tunnel management must be fail-safe around the clock. This requires safe and reliable cabling. Our high-quality Firetuf cable series are optimised for applications in tunnel operation such as fire detection, fire alarm systems, light and ventilation control and escape route systems and guarantee a highly available cable infrastructure.”
Draka is part of Prysmian Group, one of the world’s leading cable manufacturers.
