Our PLB (Permanently Lubricated Bore) HDPE Duct Pipes are engineered for effortless optical fibre cable installation in telecom and broadband infrastructure. Manufactured from high-quality HDPE (PE 80 / PE 100) resin, these ducts feature a co-extruded silicon inner lining that reduces the coefficient of friction — allowing smooth cable blowing and pulling over long distances.
Compliant with IS 14930 (Part 2) and approved by major telecom operators including BSNL, Reliance Jio, and Airtel, our PLB HDPE Duct Pipes are the industry-preferred choice for underground cable protection across India.
