{"product_id":"west-penn-d25454bk1000","title":"West Penn D25454BK1000 Miniature Plenum Shielded Broadcast Audio Cable","description":"\u003cp\u003eThe West Penn D25454BK1000 is a broadcast-grade miniature audio cable engineered for AV integrators and broadcast engineers routing line-level audio, low-voltage power, or rack cabling through plenum-rated indoor spaces. Its CMP NEC designation satisfies fire code requirements in commercial and broadcast facilities where standard cables cannot be used, making it a practical choice for above-ceiling and air-handling plenum pathways without conduit.\u003c\/p\u003e\u003cp\u003eThe twisted-pair construction with 100% aluminum polyester foil shielding and a drain wire positioned inside the foil shield delivers consistent EMI and RFI rejection across long runs in electrically dense rack environments and broadcast suites. ASTM tinned copper conductors resist oxidation over time, preserving connection integrity at patch points and terminal blocks. At 22 AWG with FEP insulation, the cable maintains flexibility in tight plenum spaces while meeting the stringent NFPA 262 flame rating required by UL and cUL listings.\u003c\/p\u003e\u003cp\u003eSupplied on a 1000 ft standard spool, this cable is a direct Belden 9451P equivalent, allowing integrators to substitute on existing bill-of-materials without requalification. Its slim nominal OD keeps conduit fill efficient and termination clean across high-density audio infrastructure projects.\u003c\/p\u003e","brand":"West Penn Wire (Belden, Inc.)","offers":[{"title":"Default Title","offer_id":52446120968376,"sku":"39058","price":259.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/39058_WESTPEN-D25454BK1000_ALT01sqr.jpg?v=1783609137","url":"https:\/\/soundpro.com\/products\/west-penn-d25454bk1000","provider":"SoundPro","version":"1.0","type":"link"}
