As per TEC Specifications (GR No.TEC/GR/TX/CDS-008/03/MAR-11 with latest Amendments) or customer requirements, Permanently Lubricated HDPE Ducts are formed by co-extrusion technique using ultra-violet (UV) stabilized grade of HDPE with required Anti Oxidant content and other recommended additives. The inner layer of ducts is silicon coated which minimizes the friction between OFC and the duct during the process of blowing the cable into the ducts, thus providing smooth installation of OFC in the duct without damaging the cable fibers.

PLB Duct Pipes are used as underground cable conduits for laying optical fiber cables, communication cables etc. & are suitable for cable installation by blowing or pulling by rope techniques. PLB Ducts are suitable for Telecommunication, Computer Network, Automatic Signaling, Railways Information Network, Highways, Cable Service Providers, Broad Band networks, Electric cable installation etc.
