Unlocking the Secrets of Pre-Laid Cable Duct

Date: 2023-09-06 17:25:00

How can telecom manufacturers and providers meet today’s infrastructure needs, creating a path for new growth, while reducing construction costs down the road? Deploy pre-laid cable duct (PCD). PCD can reduce the cost of installation and construction. This article will lead you to know about PCD. 

What is PCD?
PCD is high-density polyethylene (HDPE) duct with pre-laid cable. The cable is pre-laid into the duct safely by a special smart fitting.


What are the Benefits of Using PCD?
● Reduce the cost of cable installation and lower the freight cost
● Save the set-up expense on manholes (hand holes)
● Reduce the cost of construction

Is There an End Difference for PCD?
There is no end difference for the PCD, but the cable has an end difference. To guarantee the end-to-end cable, the cable end should be placed as per the end difference in order. Before and after pre-laying the cable into the duct, we need to check the cable end difference and mark it on the drum. End caps of different colors are used to mark the cable end.


How to Use PCD in the Area with Complicated Road Situations and the City?
PCD can be put directly into the other larger diameter pipe. But because PCD cannot cut at will, in the city or crossing area between city and country where there are lots of barricades, it is difficult to construct in a long length. However, the silicon duct can be chosen to be constructed by part for later cable blowing or man-made cable placement by a short distance. 

Accessories for PCD
1. A cable simplex plug effectively seals conduits containing one cable by sealing the space between the duct and the cable. It is reusable and removable, air- and water-resistant, corrosion-proof, and prevents dirt and dust from entering the conduit.
2. The duct plug has anchored and organized subducts or multiple duct systems. It Eliminates duct-edge abrasion on cables and is excellent for supporting cables at the tops of risers.
3. Heat-shrink cable repair sleeve is designed to repair damaged cable sheaths. It is suitable for use with cable joints or as additional corrosion protection on undamaged cables.


PCD is used in the core network, metropolitan area network, access network, etc.


PCD is flexible and durable and reduces the cost of projects, including saving the ocean freight of duct and cable and construction. In addition, PCD has aging-resistant, anti-corrosion of chemicals, waterproof, damp-proof, and can avoid damage by rodent animals.
