Himalyan PLB HDPE Ducts

Himalyan PLB HDPE Telecom Ducts

Permanently Lubricated (PLB) HDPE Telecom DUCT…

The Permanently-Lubricated HDPE Telecom Duct consists of two concentric layers, the outer layer being HDPE; co-extruded with an inner layer, which is distributed uniformly along the entire inner surface of the duct to drastically reduce the Internal Co-efficient of Friction (ICF). These Telecom Ducts with smooth inner surface facilitate easy insertion of Cable manually or by blowing technique and provide total protection to optical fiber cable, co-axial cables and electric power cable during and after installation. Himalyan has installed the most modern plant for manufacturing of these Ducts with and without Nylon Rope at their factory located in the ideal environment at Chambaghat, Solan (Himachal Pradesh) India.
