In order to know what bulk plenum cable is, we will discuss what the word plenum means. The word plenum is the name of a space in any building that is not used by humans.

Plenum spaces in a building are such areas as the space between the ceiling and the drop ceiling or the space under a raised floor where bulk plenum cable is laid.

These spaces are used in facilitating air circulation for air conditioning and heating of the building. They also provide a path for heating and cooling air ducts that runs along the side of bulk plenum cable.

There are such times when there is not enough room between the ceiling and drop ceiling and if this occurs to where there is no air flow, then the space may not be called a plenum space.

This plenum space in buildings is normally used for the heating and cooling system but it is also used for the communication bulk plenum cable that run the buildings best housed computers and telephone network.

Many buildings have abandoned the use of plenum spaces for use of their communication bulk plenum cable due to the fact that most of the time, the bundle of bulk plenum cable that are needed in today's major building is far too large in order to fit into the plenum spaces.

But there has been data that suggest this proposes a major hazard because in the case of fire, the bulk plenum cable helps to limit the flames to spread and when these plenum spaces are not being used, the fire actually gets worse because of the fresh oxygen that is held by these spaces.

According to the ASHRAE which is the American Society of Heating, Refrigerating, and Air Conditioning Engineers, the main concern in the bulk plenum cable is the increased load on suspended components.

Plenum spaces are not allowed to be used for storage or for abandoned bulk plenum cable or for any high voltage powered equipment due to the fire hazard that may be involved.

The National Fire Protection Association regulates the plastics that are used to make bulk plenum cable. Bulk Plenum cable is wrapped with a fire retardant plastic that is a low smoke polyvinyl chloride or it can also be plastic that is a fluorinated ethylene polymer.

All the materials that need to used for the wires and bulk plenum cable to be placed in plenum spaces have to go through a rigorous fire safety test and they have to pass all the standards that are outlined in accordance to fire code NFPA 262 and fire code NFPA 90A.
