Plenum-rated cables are distinguished from other types of cabling by the special types of plastics used in their jackets. Because plenum cables are routed through air circulation spaces which contain very few fire barriers, they need to be coated in flame-retardant, low smoke materials such as polyvinyl chloride (PVC), fluorinated ethylene polymer (FEP), or a polyolefin. These plastics offer good resistance against fire, and in the event that they do begin to burn, they will not emit large quantities of harmful fumes.
If your cabling application requires materials that are flame-retardant or compliant with strict safety standards, opt for plenum-rated products. CableOrganizer.com offers a full line of plenum-grade cable, raceway, and wire connectors to meet all of your fire safety requirements!
