Direct Buried Micro Duct For Air Blown Cable

Tube bundle is made by one micro duct or more than one micro duct grouped according to a certain arrangement order with outer sheathing layer. It can hold more conduits in the limited space.

The structure of HDPE tube bundle has some characteristics as follows:

 1. The technical specification of micro ducts grouped into tube bundle fully comply with the above-mentioned specification of micro duct;

2. Through the color, arrangement definition, ie, the position of each micro duct in the tube bundle, the construction becomes convenient so as to effectively avoid the misconnect of micro ducts;

3. Inner micro ducts and the outer sheathing layer can be relatively separated through a special manufacturing technology and product formulation so as to convenient for construction and the connection of inner micro ducts;

4. Many tube bundles placed into the same one trench can be distinct through the different color of outer sheathing layer of tube bundle or different strips on the outer sheathing layer of tube bundle;

5. The surface of outer sheathing layer of tube bundle is smooth without defects, such as visible holes or scars.
