Which type of fire-resistant cable is known for its low smoke-producing characteristics?

Plenum cable is specifically designed for use in areas with high air circulation, such as air ducts, where fire safety and low smoke production are critical. This type of cable typically has a special coating that reduces the amount of smoke and toxic fumes generated during a fire, which is crucial for maintaining safety in enclosed spaces where smoke can quickly spread and pose additional hazards.

Understanding the fire-resistance properties of different cables is essential in ensuring compliance with safety regulations, particularly in commercial and residential buildings where ventilation systems could allow smoke to travel more freely. The ability of plenum cables to minimize smoke production helps enhance visibility and improve the chances of safe evacuation during a fire, making them a preferred choice in scenarios where fire safety is a primary concern.

In contrast, the other types of cables listed do not prioritize low smoke generation to the same extent, as they are typically designed for different applications that may not have the same stringent requirements for fire safety and smoke emission.
