About PLB Duct Pipes
PLB Duct Pipe (Pre-Lubricated Bore Duct Pipe)
PLB duct pipes are high-density polyethylene (HDPE) ducts with a factory-applied internal lubricant layer that reduces friction. They are designed for easy and efficient installation of optical fiber or telecom cables using air-blowing or pulling methods. The smooth inner surface minimizes cable damage and allows longer blowing distances. PLB ducts are lightweight, flexible, corrosion-resistant, and suitable for underground, direct burial, or duct bank installations. They offer excellent mechanical strength, long service life, and resistance to moisture, chemicals, and environmental stress.
