HDPE Pipe Micro Duct 7ways 10/8mm for Underground Fiber Optic Cable
The HDPE micro duct for installation of fiber optical cable blowing, is a kind of small, flexible, lightweight tube with an outer diameter typically less than 16.0mm.
The micro duct has a circular and uniform in cross-section throughout its length, its inner surface have a low coefficient of friction, and longtitudinal ribbed inner wall, to reduce the inner friction coefficient of the micro duct so as to be beneficial to cable blowing.
Micro ducts of high density polyethylene with HDPE as the main raw material, are the composite pipe with inner wall made of silicon material lining made by the advanced plastic extrusion forming technology, the inner wall of this duct is a solid permanent lubrication layer, which has self lubricity and effectively reduce the friction resistance between the cable and duct when the cable is repeatedly extracting in the duct.

The application of micro duct products, combined with micro optical cable and air blown cable technology, makes the construction of communication optical cable pipeline network flexible, economical and efficient, and solves the current situation of tight and difficult construction of pipeline resources.
