Uses For Plenum Cable
The space below the flooring or above the ceilings in a building is called the Plenum space. It’s an area that can serve a variety of purposes but is most commonly used to house the HVAC services in the building – heating, ventilation and air conditioning. The other thing it’s used for is running out plenum cable.
Plenum Rated Cable is manufactured to NFPA 90A: Standard for the Installation of Air Conditioning and Ventilating Systems for use in the US and to similar standards for use in other countries. All the components in the wiring, and particularly the jacketing, must meet rigorous fire safety standards and are tested in accordance with NFPA 262 to ensure their compliance with the standard. The special insulation and jacketing materials consist of low smoke PVC, Halar, Kynar or FEP.
Cat5e and Cat5e Plenum cable are both twisted pair cables used to carry signals across networks, like an Ethernet computer network. The difference between them is that the plenum cable has an outer jacket, and wire pair coating, that are flame retardant and produce less smoke in the event of a fire. Cat6 Plenum cable is faster than Cat5 and has less signal interference with the same fireproof qualities. Both are mandatory for data cabling in plenum spaces.
