Introduction: Direct Install Aluminum “DIAL” Microduct Assemblies consist of tubes with a smooth or ribbed inner surface that enables an air blown installation of micro cables. The micro ducts are sheathed with one layer without moisture barrier. It provides excellent protection from the physical environment withstanding significant amount of pressure by pulling, and it is easy to branch off for network expansion. Direct Install Aluminum duct is for installation duct and sub duct. This product will install in the existed infrastructure to maximize DIAL advantage with the Aluminum tape which helps to block the water from the extreme wet soil condition. It is recommended to earth regular interval with aluminum or use metal free products Application: The tight protected duct assemblies consist of a number of microducts with an inner low friction, antistatic surface that enables installation of air blown fibers unit cable. The duct assemblies are bundled with a single HDPE sheath depending on configuration. The design makes the duct assemblies especially suitable for installation into narrow existing ducts (pipes) or pipes occupied with cables or other obstacles Operation Features: The duct assemblies are available in several versions with 1 to 24 and 24+1 microducts. Each microduct has an outer/inner diameter of 5/3.5 mm. These are suitable for installation of air blown fibers. The center duct of 24+1 way assemblies is 10/8 resp. 12/10 mm and can be used for blowing in a micro cable. • For installation in existing ducts • 1, 2, 4, 7, 12, 19, 24 or 24+1 over-sheathed ducts • 5/3.5 mm microducts • Low friction inner surface for maximum installation lengths • Aluminium moisture barrier • Excellent environmental properties • silicone coated inner tube • Material HDPE Inner tube and Outer sheath • Maximum Air Pressure (Blowing) 15bar Temperature Performance: Storage and Transportation [°C]: -40 to +60 Installation [°C]: -20 to +50 Operation [°C]: -40 to +60 Mechanical Performance Test compliance: Tensile Performance: IEC 60794-1-21 Method E1 Bend: IEC 60794-1-21 Method E11 Kink: IEC 60794-1-21 Method E1 Impact: IEC 60794-1-21 Method E4 Crush: IEC 60794-1-21 Method E3 Inner Clearance: IEC 60794-5-20 Ann.E Marking: Duct assemblies have markings showing the tube length. The individual microducts are numbered and also identified by their color and position in the bundle.
