Insulated flexible cables with thermal resistance up to 140°C are used as connection elements in ventilation, air conditioning and recuperation systems. The inner frame, made of spirally wound steel wire with increased strength, ensures proper rigidity and maintaining the shape of the cable. – fire-resistant aluminum layer – insulation material – glass wool 25 mm thick – packed in 5 and 10 meter sections parameters Insulation thickness25 mm Constructionaluminum + glass wool + polyester laminated with aluminum foil Dimensions102 mm – 203mm Standard length5 m and 10 m Temp in-30 °C / +140 °C Temp exit-30 °C / + 140 °C Flammability class non-flammable FR (NF): M1
