West Penn Wire 25293BGY1000 18AWG 2pr Shielded Plenum Cable

Product Description

The WEST PENN WIRE 25293BGY1000 is an 18 AWG, 2-pair shielded audio cable rated for plenum air-handling space installations. It carries low-level and line-level audio signals in commercial and institutional buildings where air duct and plenum ceiling routing is required by code. The gray jacket identifies this as a plenum-rated product, and the overall shield provides protection against electromagnetic interference common in commercial electrical environments. This cable is sold as a 1000-foot reel, making it suitable for large-scale audio distribution runs. It is installed by licensed low-voltage technicians and systems integrators working in commercial construction and retrofit projects.

This cable is used in commercial audio distribution systems routed through plenum-rated air-handling spaces such as suspended ceiling plenums and HVAC supply and return ducts. Typical applications include background music systems, paging systems, intercom wiring, and distributed speaker runs in offices, schools, hospitals, and retail environments. The shielded 2-pair construction supports clean signal transmission over longer distances where noise rejection is a priority.

Key Features

• 18 AWG stranded conductors support extended audio signal runs with low resistance
• 2-pair configuration allows dual-channel or independent signal routing in a single cable
• Overall shield reduces electromagnetic and radio-frequency interference pickup
• Plenum-rated jacket meets fire and smoke propagation requirements for air-handling space routing
• Gray jacket provides visual identification and conforms to common low-voltage color conventions
• 1000-foot reel length suits large commercial audio distribution installations

Compatibility

Designed for use in commercial low-voltage audio distribution systems requiring plenum-rated, shielded 2-pair cable in plenum ceiling and air-handling space pathways.

Installation Notes

Installation must be performed by a licensed low-voltage or electrical contractor in accordance with NEC Article 800 and applicable local codes governing plenum-rated communications cable. Confirm that the ceiling or space is classified as a plenum air-handling environment before routing this cable, as plenum rating is required where HVAC return air circulates. Maintain proper bend radius to avoid damaging the shield and jacket, and terminate shields to ground at one end only to prevent ground loops in audio circuits.
