HDPE PLB Telecom Duct
Gamson India is a manufacturer and supplier of HDPE PLB Telecom Ducts with its manufacturing unit based near Delhi NCR in Sonipat, Haryana. These Permanently Lubricated (PLB) HDPE Ducts are made using High-Density Polyethylene (HDPE) material which provides them excellent flexibility, corrosion resistance and durability. Gamson India has engineered these HDPE PLB Duct Pipes specifically for protection and casing of Optical Fiber Cables (OFC), telecommunication cables, electrical cables, communication networks, etc. during above-ground and underground installations.
The "PLB" designation in HDPE PLB Telecom Ducts Pipes refers to a specialized Permanently Lubricated coating of a solid lubricant that is co-extruded in the internal surface of HDPE Ducts during manufacturing. This inner layer helps in significantly reducing the coefficient of friction, thus allowing for long lengths of fiber optic or electric cables to be blown or pulled through the duct with minimal effort and without any damage to the cable.
Gamson manufactures these HDPE PLB Telecom Duct Pipes in all sizes and colours as per customer requirements. HDPE PLB Ducts are manufactured as per Telecommunication Engineering Centre (TEC) standard specification TEC 72030:2025 (formerly TEC/GR/FA/CDS-008/04/AUG-2019) or as per RDSO Specification No. RDSO/SPN/TC/45/2012. Contractors and network integrators can buy these pipes from Gamson India at reasonable rates. These PLB Ducts can be provided in the standard sizes of 32/26 mm, 40/33 mm, 50/42 mm, 63/50 mm, 110/80 mm, or any other size with Blue, Orange, Black, Red, Green, Yellow, Brown, Grey, Violet, or any other colour as required by the customer.
Key Features
- Permanently Lubricated (PLB) Inner Layer: HDPE PLB Telecom Duct Pipes consist of an internally lubricated surface to reduce friction allowing for installation of Optical Fiber Cables by blowing techniques. This internal lubrication coating is permanent by nature and does not wear out due to environmental or operational factors with time.
- Vast Variety of Accessories: HDPE PLB Ducts come with wide variety of compatible accessories that can be used to serve customized requirements of clients during cable installation projects. Accessories like Duct Coupler, End Plug, Cable Sealing Plug/ Simplex Plug, etc. are readily available for sale by Gamson India.
- Superior Crush Resistance: These PLB Ducts are made using High-density Polyethylene material which allows the duct to withstand heavy soil loads and traffic vibrations when buried in urban or highway environments.
- Impact & Environmental Strength: Since these HDPE Pipes for cable are resistant to chemicals, moisture, and other compounds generally found in soil, they are an ideal fit for protecting fragile fiber optic or electric cables during installations.
- Colour Coding for Easy Identification: Available in a wide spectrum of vibrant colors (Blue, Orange, Black, Red, Green, Yellow, Brown, Grey, Violet, or any other colour), these colour-coded HDPE Ducts can be easily identified by technicians enabling them to differentiate between different network providers in a shared trench.
- Flexible Yet Tough: Can be easily coiled around underground obstacles without the need for specialized elbows or fittings.

Primary Applications
- Fiber to the Home (FTTH): HDPE PLB Duct Coils are used for protection of Fiber Optic Cables that provide internet delivery to residential and industrial areas by Internet Service Providers (ISPs).
- Railways & Defense: HDPE Pipes are used for protecting secure, underground communication lines for sensitive data transmission.
- Smart City Infrastructure: These pipes are used for protective casing for cables for CCTV surveillance, traffic management systems, and public Wi-Fi.
- Data Centers: HDPE PLB Duct Pipes are used in interconnecting massive data hubs with each other using high-bandwidth optical links.
- CATV Networks: Used by cable television providers for shielding signal distribution cables.
Jointing & Accessories
To ensure a continuous, airtight path for cable blowing and cater to customized customer requirements during cable installation projects, Gamson PLB Ducts are used with following accessories:
- Duct Couplers: Push-fit or threaded duct couplers that provide an airtight and watertight seal between duct ends. They are used to join two pieces of HDPE Duct Pipes together.
- End Plugs: Used to seal the duct ends to prevent the entry of mud, water, or insects before the cable is installed.
- Cable Sealing Plug: Also known as simplex plug, they are used to seal the space between the cable and the duct to prevent moisture, dirt or insect entry.
- Compression Tee & Compression Elbow: For creating branch connections or navigating sharp angles.
- Duct Rodder: A flexible rod used to pull cables or cleaning sponges through the duct.
- Duct Cutter: The Duct Cutter is a precision manual tool designed to provide perfectly square, burr-free cuts on HDPE pipes.
- Chamfering Tool: The Chamfering Tool is used to create a beveled edge on the outside of the duct end which makes the installation of duct coupler and prevents damage to rubber seal in duct coupler due to the sharp edge of HDPE PLB Telecom Duct.
