Ducting

Polyethylene duct is generally used for the protection of fibre optic cables. The inner wall of the duct is sometimes provided with uniform longitudinal grooves or spiral ribs. When the cable is pulled or blown through the duct the grooved design provides only point contacts between the cable and the internal surface of the duct, reducing the coefficient of friction significantly.

The polyethylene cable ducts offered by Omanplast™ are plastic cable ducting derived by combining the strength and flexibility of PE material with a suitable lubricating layer on the inner surface of the ducts. The adhesion of inner silicone liner to the PE duct is uniform and strong, the outer ducting of the PE material provides the necessary mechanical and electrical properties to the fibre optical cables passing through them. Whilst the inner silicone sheath layers provide the necessary smooth, lubricated surface for the optical cables to be drawn through at the time of installation.
