Plenum Rated Cable

Through the suppliers Belden and Omni Cable, we provide total access to Plenum Rated Cable for applications that require reliable electrical power in constructions with plenum areas. Most commonly, plenum spaces are those that lie above dropped ceilings or underneath floors that are raised. As a result of these areas’ increased tendency toward fire risks, the cable varieties made for such applications have to meet greater safety standards regarding flame retardance than other types of cable. Plenum-rated cables have a multi-conductor construction that is available without shielding, with signature Beldfoil shielding, or with overall foil and braid shielding.

In accordance with National Electrical Code (NEC) classifications, the Plenum Cables we carry are rated as Type CMP. All of these are rated to 300 volts and include tinned copper conductors, as well as insulation made of FEP and jacketing material constructed of FEP or Flamarrest. The other primary difference between varieties of Plenum Rated Cable is the shielding material.

Our full inventory of plenum-rated cable products from Omni Cable and Belden encompasses a variety of options for increased safety in the use of various plenum applications. Any compartment or chamber that has at least one air duct connected to it as part of a system for air distribution is known as plenum. Those options of plenum cable that are unshielded are non-conduit and are made with fluorinated ethylene polymer (FEP) or low-smoke polyvinyl chloride (PVC) jackets, in addition to having approval for their use in normal plenum applications, direct burial, and outdoor environments. Both types of plastic jackets on plenum rated cable are specially designed to have fire retardance capabilities.

Plenum cable meets a number of classifications and standards for safety and usage. For instance, they are approved by Underwriters Laboratories (UL) to be installed in plenum applications without a need for the use of conduit. The cable used in these settings has also met flame test requirements under UL standard 910 CMP.

At OneStopBuy.com, we offer a product selection tool on the left-hand-side of our site for narrowing cables down according to specific criteria. Under the AWG size category, for example, you can select products ranging from 12 to 24 gauge depending on the size required. The number of conductors in a given cable product can be chosen in configurations ranging from 1 to 12, with additional options for features like pairs and the presence or absence of shielding material. Constructions for these cable varieties include choices like bonded-pairs, coaxial, twisted pairs, and twinaxial pairs, among others.

Belden and Omni Cable provide a significant amount of plenum-rated cables that comply with the requirements for NEC Type CMP and CEC Type CMP FT6 cables. Aside from standard plenum systems, these cables are also made use of in control and instrumentation applications like computers, audio, fire alarm systems, and communication. To suit these different applications, we supply Belden and Omni Cable products in a variety of constructions and materials.
