Which of the following cables comes coated with a flame-resistant jacket?Group of answer choicesUTP cablePVC cableSTP cablePlenum cable

To determine which of the following cables comes coated with a flame-resistant jacket, let’s analyze the options provided:

1. UTP cable (Unshielded Twisted Pair): This type of cable does not typically have a flame-resistant jacket. It is commonly used for network connections but lacks specialized fire-resistant properties.

2. PVC cable (Polyvinyl Chloride): While PVC cables are common and used for many electrical applications, standard PVC cables are not inherently flame-resistant. They may emit toxic fumes when burned.

3. STP cable (Shielded Twisted Pair): Similar to UTP, STP cables are shielded to reduce electromagnetic interference but do not generally feature a flame-resistant jacket.

4. Plenum cable: This type of cable is specifically designed for use in spaces used for air circulation for heating and air conditioning systems (plenum spaces). Plenum-rated cables are coated with a flame-resistant jacket to meet fire safety codes, making them safe for installation in these areas.

Final Answer

Plenum cable is the option that comes coated with a flame-resistant jacket.
