Happy New Year 2023

We must keep the installation area in mind when installing wires in a building. Different environments may demand the use of different cables such as Category Cables Plenum. This article will provide a quick comparison of the three types of cables.

Plenum Cable:

A plenum is a separate room in a building used to circulate air for heating, cooling, and air conditioning. Plenum cable should install in every space that handles air. Fire-resistant cables should put in the region. The communication cables for the building’s computer and telephone network are often located in this area.

  • Plenum cable offers the highest fire-retardant ratings, making it ideal for air-flow locations.
  • Plenum-rated cables are designed for use in regions with air circulation and return air.

Riser Cable:

A riser, unlike a Category Cables Plenum, connects one floor to the next within a building. Risers include elevator shafts and cables that connect floors. Fire-resistant cables should be used in risers to prevent flames from spreading up the cable. Polyvinyl chloride (PVC) makes the jacket (PVC).

  • Riser cables are widely used in non-plenum environments for regular networking from floor to floor.

PVC cable:

PVC cable’s qualities as a plastic material make it suited for uses where the cables may be subjected to high or low temperatures or when UV radiation protection is necessary to avoid damage. Because of its strong insulating characteristics but poor resistance, the PVC layer is often used for medium voltage power cables and lower frequencies shielding needs.

  • Indoor and outdoor electrical cables are the two types of PVC insulated cables.
  • When purchasing PVC cable, be sure that the type you select fulfills your requirements.

PVC Cable Vs. Plenum Cable Vs. Riser Cable:

The most important consideration is safety. However, there are a few more reasons:

  1. Plenum cables, like Cat5e Plenum Cable also called CMP cables, are installed in building plenum spaces.
  2. Plenum cables are better for commercial and residential use since they have a greater fire rating.
  3.   Plenum cables are the most common alternative for air duct cables.
  4. Riser cable is more affordable than plenum cable because of the difference in safety rules and jacket material.
  1. However, riser cables are still the safer alternative for everyday purposes.
  2. Both business and residential settings can benefit from riser cables.
  3. While Plenum cables can be used for riser cables in a riser-designated space, plenum-rated cables cannot be replaced for riser-rated cables in a plenum-designated space.
  4. PVC cables are popular for their durability.
  5. PVC can be used for various electrical wiring purposes, such as home cabling and main circuit electrical connections.
  6. However, it is important to note that various types of PVC cables exist. Each type of cable has its own set of applications.


To summarize the differences between PVC, plenum, and riser-rated cables, the cost is a key consideration, but it comes down to how fire-resistant their jackets are and how much smoke is produced if they burn. Plenum cables are less likely to catch fire than riser cables because of their superior fire resistance.
