The advantage of using plenum cable for twisted- pair cable  is it is "Fire resistant"

Explanation:

Plenum cable is a cable that is used in plenum spaces of buildings. These cables have fire resistance characteristic with low smoke. These cables are self extinguishing, and never re-ignite. They require less space for installation and allows space for air circulation to be used by the HVAC system. Twisted-pair, coaxial, HDMI and DVI variants of cable are manufactured in the plenum version. Plenum cable is mandatory to be fixed in any "air handling" area.
