Direct Bury Metal Free Microduct - Lenora Innovation

The Direct Bury Metal Free microduct assemblies consist of a number of microducts with an inner low friction surface. The duct assemblies are bundled with a single or dual HDPE sheath depending on configuration. The design makes the ducts suitable for installation directly into the ground.

Direct Bury Metal Free Microduct 5/3.5

Overview: Direct Bury Metal Free “DBMF” 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 two layers 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. Duct is designed for high crush resistance from external pressure. The thin inner tube wall can make it easy to bend or fix inside of cabinet/closure. The extra layer (total 2 layers of the outer sheath) is added to protect the thin wall of inner tube from external ground pressure. Flexibility of tube allows bending or fixing inside of cabinet/closure. It is strong against lightning, electrical surge. 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 cables. The duct assemblies are bundled with HDPE sheath depending on configuration. The design makes the ducts suitable for installation directly into the ground. 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 direct burial • 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 • 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.
