The larger conductor size is what integrators reach for when a control or audio home run is long enough that voltage drop and loop resistance start to matter, and the plenum jacket lets that same run pass through an air-handling ceiling without conduit. A full aluminum foil shield and a bonded tinned copper drain wire complete the build.\u003c\/p\u003e\n\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e20 AWG tinned copper pair at 0.038 in (0.97 mm) per conductor for long-distance runs.\u003c\/li\u003e\n  \u003cli\u003eNEC CMP and C(UL) 60 °C ratings for installation in return-air plenums.\u003c\/li\u003e\n  \u003cli\u003eFoamed FEP insulation, PVC inner jacket, blue fire-resistant PVC outer jacket.\u003c\/li\u003e\n  \u003cli\u003eAluminum foil shield at 100 percent coverage plus a bonded tinned copper drain wire.\u003c\/li\u003e\n  \u003cli\u003eNominal overall diameter of 0.135 in (3.43 mm) and 45 ohms nominal impedance.\u003c\/li\u003e\n  \u003cli\u003e1,000 ft (304.8 m) self-dispensing spool weighing 15 lb, with sequential footage markings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eCampus-scale and multi-floor installs where plenum construction is mandatory and the cable still has to reach: distributed audio in airports and stadiums, hospital paging and nurse-call adjacent AV, university lecture buildings, and control trunks between equipment rooms and remote racks.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eConductors: 1 shielded twisted pair, 20 AWG tinned copper, 0.038 in (0.97 mm)\u003c\/li\u003e\n  \u003cli\u003eNominal core OD 0.050 in (1.27 mm); nominal overall OD 0.135 in (3.43 mm)\u003c\/li\u003e\n  \u003cli\u003eJacket: blue fire-resistant PVC, plenum; NEC CMP, C(UL) 60 °C\u003c\/li\u003e\n  \u003cli\u003eStandard length 1,000 ft (304.8 m); shipping weight 15 lb (6.8 kg)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAlso referenced as Extron STP20P1000, STP20P-1000, part number 2215903.\u003c\/p\u003e","brand":"Extron","offers":[{"title":"Default Title","offer_id":52302124253404,"sku":"EXTRON-STP20P1000-2215903","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/5582\/4092\/files\/22-159-03-sq1080.jpg?v=1787252644","url":"https:\/\/www.ampronix.com\/products\/extron-stp20p-1000-22-159-03","provider":"Ampronix","version":"1.0","type":"link"}
