PLB HDPE Telecom Pipe (32mm to 63mm)

HDPE ducts are formed by co-extrusion technique and are used for laying the fibre cables in underground ducting / conduits.

PLB HDPE Ducts are manufactured by using

High-Density Polyethylene

Sizes: 32 mm to 63 mm Colour: ORANGE, RED, GREEN & BLUE

PLB HDPE Telecom Pipes (Permanently Lubricated High-Density Polyethylene Ducts) are specialized plastic conduits used primarily for protecting and routing underground fiber optic cables, telecommunication wires, and electrical lines.

Core Characteristics & Specifications

Size Range: Outer diameters typically range from 32 mm to 63 mm, accommodating single or multiple fiber optic cable bundles.

Co-Extrusion Technology: Manufactured via multi-layer co-extrusion. The outer layer provides high mechanical strength and impact resistance, while the inner layer features a solid permanent lubricant coating.

Permanent Lubrication: The internal coating significantly reduces the coefficient of friction, allowing optical fiber cables to be pulled or blown (using compressed air) across long distances without damaging the cable sheath.

Color Coding: Commonly available in standard colors like Orange, Red, Green, and Blue to allow easy identification and categorization of cable lines underground.

Key Advantages

Smooth Cable Installation: The low friction inner surface drastically reduces pull tension during cable installation.

Durability & Strength: High resistance to crushing, soil loads, impact, and stress cracking.

Corrosion & Chemical Resistance: Immune to rust, soil chemicals, acids, alkalis, and moisture, ensuring a long underground service life.

Flexibility: Flexible enough to navigate soil contours, bends, and obstacles without requiring excessive fittings or joints.

Typical Applications

Backbone telecommunication network deployment (4G/5G fiber optic rollouts).

Underground cable routing for internet service providers (ISPs) and cable TV networks.

Municipal, railway, highway, and power utility cabling systems.
