Ideal for voice applications and is commonly used for telephony purposes. It has fewer twists then Cat5e which makes it easier to work with when punching it down. It also has no spinal divider like the Cat6 cable does. Cat3 plenum is mandatory to use where a plenum fire rating is required. It has a Teflon jacket rather than polyvinyl chloride (PVC) and gives off less toxic fumes in a fire. Our Cat3 Plenum cable is American made and of a much higher quality then some of the imported cable that's available online.

What is plenum cable?

The plenum is hidden space within a building which is used for HVAC (Heating, Ventilation, and Air Conditioning) and to run cables. Plenum space is normally above a suspended ceiling or under a raised floor. Buildings without plenum spaces will have cabling and HVAC ducts within plain view. The plenum space is normally used to accommodate the communications wires for the building's computer and telephone network. Recent studies have shown that wiring and cabling within the plenum space could be dangerous and be exposed to fire/burning possibilities.
