What is Plenum Cable?
Plenum grade cable is a cable that uses fire resistant material such as Teflon for insulation. This type of material in the insulation minimizes the amount of smoke in case of fire. However, plenum cabling are more expensive and less flexible than a PVC cable. This type of cable is generally used in space reserver for air circulation in air conditioning and heating systems.
PVC
PVC (Polyvinyl Chloride) is a form of plastic, which is widely being used in the manufacture of cable insulation.
The advantages of PVC cables are that they are flexible, and economical. However when it burns, it produces poisonous Halogen gases such as fluorine, chlorine, bromine, and iodine.
