engineered for telecom
PLB HDPE Duct
GANGOTRI PLB HDPE Ducts (Pre-Lubricated Ducts) are specially designed for smooth and efficient installation of optical fiber cables. Manufactured with a permanent silicone-coated inner surface, these ducts significantly reduce friction, enabling faster cable blowing and pulling over long distances making them ideal for telecom and broadband infrastructure projects.
Ultra-Low Friction
Silicone-coated lining
IS 4984 Standards
ISO Certified Production
Core Advantages
Permanent Pre-Lubrication
Our unique co-extrusion process integrates a permanent silicone layer within the HDPE pipe, eliminating the need for external lubricants during cable installation.
High Durability
Built to withstand soil pressure and chemical exposure for 50+ years.
Flexibility
Easily navigates curves and obstructions without
compromising structural integrity.
Lightweight
Reduced transport and labor costs and efficient coil handling.
Reduced Labor
Faster blowing speeds translate to fewer man hours per kilometer.
