High Density Polyethylene (HDPE) ducts are used for the construction of underground duct system for fiber optic and copper cables in the telecommunication’s outside plant network. HDPE duct intended to be installed by direct buried in a normal trench or mini trench at standard depths. Today HDPE duct widely used in FTTH network all over the world.
The HDPE ducts are intended for housing of copper or fiber optic cables installed by traditional pulling techniques. Also, the ducts can accommodate fiber optic cables that are installed by blowing method. HDPE duct also provide the strong protection of optical cable from environmental conditions. The HDPE ducts and its accessories shall be unaffected by all kinds of corrosive liquids and other compounds which exist in the underground system.
The HDPE ducts shall be supplied according to the requirements.
For Mini-ducts 32 and 20mm (in addition to Black in color with 4 orange equally spaced stripes), they shall be available in 2 additional colors: full Black and full Orange
Supply lengths- 300,500, 600, 900,1000 and 1200 m, unless requested otherwise or other lengths agreed by telecom operators.
Bending- Maximum permissible bend radius 30 times OD in temperature 20°C.
Cuttings – Can be cut using either a specialized cutter, or a sharp knife or a metal or woodworking saw.
Labeling- The HDPE duct information shall be clearly marked on the duct at the intervals of 1 meter throughout the whole length of the duct. The marking shall be durable, clear and distinct to the naked eye from a minimum distance of 50cm.
HDPE Duct Sealing Plug – Used for sealing the duct ends before cable installation, prevents ingress of dirt, water, moisture, insects etc.
HDPE Duct 90° Bend – Long sweep 90° bend is used for routing of conduits around corners and for the interfacing between the duct and the base of a cabinet or termination boxes.
