Belden Plenum-Rated Cable

Allied's selection of Belden plenum-rated multi-conductor cables includes unshielded plenum cable, Beldfoil shielded cable and overall foil and braid shielded plenum cable versions of audio, control and instrumentation cables. These cables are approved for use in plenum spaces which are typically the spaces above dropped ceilings and below raised floors, or other semi-enclosed spaces used for air circulation. Because these areas have greater potential to spread fire, plenum-rated cables must pass stricter fire safety requirements than most other cables.

These plenum cables are rated Type CMP cable by the National Electrical Code (NEC). They are rated to 300 volts and share similar constructions, featuring tinned copper conductors, FEP insulation, and either FEP or Flamarrest jacketing. The main difference lies in the shielding. These cables are either unshielded, Beldfoil shielded or shielded with a combination of Beldfoil and tinned copper braiding.

Allied's inventory of Belden plenum-rated cable includes cable solutions for a wide range of plenum applications. The unshielded plenum cables with FEP jackets are non-conduit. They are approved for direct burial and outdoor applications in addition to traditional plenum applications. For more information on individual products, their specifications and appropriate applications, please click on the links listed above.
