Direct Bury Metal Free Microduct
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.
Overview:
Direct Bury Aluminum “DBAL” 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 3 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.
