Treotham Automation Helucom FS90 fire-safe cable range

Treotham Automation has launched the Helucom FS90 fire-safe cable range, a fibre-optic cable that ensures data communication is upheld for 90 minutes even in the event of a fire.

The range is suitable for tunnels, underground train tunnels, computer centres, in mining and in all other environments in which signal transmission must be ensured in the event of fire.

Based on the IEC 60331-25 standard, the cable has been tested for the purposes of function and data transfer under the influence of flames of 750°C for more 90 minutes.

The maximum damping increase was maintained at E9/125 μm 0.12 dB in single mode and G50/125 μm 0.27 dB in multimode.

At the same time, the range meets the standards IEC 60332-1 + 60332-3, flame resistance, IEC 61034 smoke/gas proof, IEC 60754-2 halogen freedom and EN50267-2-3 corrosiveness.

Four different cable types are available as standard inventory: 4 G50/125 μm OM2 (803917), 12 G50/125 μm OM2 (803918), 4 E9/125 μm G652.D (803919) and 12 E9/125 μm G652.D (803920).
