Which type of cable can be used in environments with high airflow, like plenums?

In environments where high airflow is present, such as plenums, it is crucial to use cable types that are specifically designed to minimize the risk of fire hazards and toxic smoke emissions. FPLP (plenum-rated cable) is engineered for these conditions, as it is constructed with a special insulation that is not only fire-resistant but also has lower smoke-emitting properties. This makes it suitable for installation in air-handling spaces, where cables can be exposed to air that circulates through the building's HVAC system.

Using FPLP cable in plenums ensures that, in the event of a fire, the cable will not contribute significantly to the spread of flames or release harmful smoke that could endanger occupants or hinder evacuation. The other cable types listed, while suitable for various applications, do not meet the same stringent safety requirements for plenums. Therefore, FPLP is the ideal choice for installations in these specific environments.
