Permanently Lubricated (PLB) HDPE Telecom DUCT…


The Permanently-Lubricated HDPE Telecom Duct consists of two concentric layers, the outer layer being HDPE; co-extruded with an inner layer, which is distributed uniformly along the entire inner surface of the duct to drastically reduce the Internal Co-efficient of Friction (ICF). These Telecom Ducts with smooth inner surface facilitate easy insertion of Cable manually or by blowing technique and provide total protection to optical fiber cable, co-axial cables and electric power cable during and after installation. Himalyan has installed the most modern plant for manufacturing of these Ducts with and without Nylon Rope at their factory located in the ideal environment at Chambaghat, Solan (Himachal Pradesh) India.With advances in technology in modern day Telecommunications, over a period of time, it became very important to upgrade the HDPE pipes to be used particularly for Telecom applications. The Optical Fibre Cables used for Telecommunications being very delicate and sensitive, it became necessary to modify the HDPE Pipes to be used as conduits for optical fibre cables. This led to the development of Permanently Lubricated (PLB) HDPE Telecom Ducts.


Advantages


  •   Ducts being very light in weight hence offer low transportation costs and easy handling.
  •   Longer and easier cable installation reducing the cost of attachments.
  •   Saving of manpower.
  •   Reduced co- efficient of friction.
  •   Overcoming difficult field and extreme environmental conditions.
  •   Supplied in nominal sizes of 32/26mm, 40/33mm, 50/42mm, 63/50mm & 110/80 mm and can be delivered in continuous’ length as per technical details provided above.
  •   Product life of over 50 years.
  •   Cost effective repairs and upgrading.

Advanced Accessories and Tools


  •   Push Fit Coupler: Used to couple two ducts and to provide air-tight joint.
  •   End Plug: For sealing the ends of empty ducts before installation of cable.
  •   Cable Sealing Plug: Used to seal the ends of ducts perfectly, after the cable is installed in the duct to prevent entry of dirt, water, moisture, insects/ rodents etc.
  •   End Cap: Fitted into both ends of Duct Coil after manufacturing the duct to avoid entry of dust, mud and rain water into the duct during transit & storage.
  •   Duct Cutter: Required to cut the duct ends squarely.
  •   C-Spanner: Tool to tighten Plastic coupler properly and to ensure air/water tightness.
  •   Blowing Equipment: For blowing/ de-blowing of Optical Fibre Cable in PLB HDPE Duct.
