EMTELLE MICRODUCT TUBING, LOW FIRE HAZARD

System Features

• Flexibility - When wrapped around a 10d mandrel (where d = tube diameter) there is no kinking or damage and an appropriate diameter ball passes completely through the microduct.
• Pressure - Micro duct withstands 17 bar air pressure underwater for 2 hours without leaks.
• Friction - Low friction lining material used to increase fibre blow distance.
• Crush - After a 1000N load (used on Polyethylene microducts) and 400N load (used on Low Fire Hazard mirco ducts) for 1minute, the residual deformation of the microduct does not exceed 15% measured within 1 minute of unloading.

Low Fire Hazard Microducts (LFH)

Assembly of 5/3.5mm LFH tubes, each with low friction performance and suitable for fibre blowing. Each assembly is surrounded with a sheath of LFH material suitable for indoor fire regulation use and giving excellent performance in a fire scenario, meeting IEC 60332-3.
