Wirepath NST-182-SH-1K-GRY 18 Awg Shielded Plenum Cable

Product Description

The WIREPATH NST-182-SH-1K-GRY is an 18 AWG shielded plenum-rated audio cable with a drain wire, supplied in a 1000-foot quantity. Plenum-rated cable is constructed with a low-smoke, flame-retardant jacket approved for installation inside air-handling spaces, including ceiling plenums and HVAC return air pathways. The shielded construction with drain wire provides protection against electromagnetic interference, making it suitable for low-voltage audio distribution in commercial and residential structured wiring applications. Low-voltage installers and audio-video integrators are the primary tradespeople who work with this cable type.

This cable is intended for in-wall and in-ceiling audio distribution runs where building codes require plenum-rated materials. Typical applications include distributed audio systems, background music wiring, and intercom infrastructure in commercial buildings, hotels, offices, and multifamily residential projects. The 1000-foot length supports longer continuous runs without mid-run splices, which helps maintain signal integrity across a full floor or zone.

Key Features

• 18 AWG conductor gauge suitable for low-voltage audio signal and speaker distribution
• Shielded construction with drain wire reduces EMI and RFI interference on the signal path
• Plenum-rated jacket meets fire and smoke requirements for air-handling space installation
• 1000-foot continuous pull reduces field splices and supports long horizontal runs
• Gray jacket color for standard identification in structured wiring installations

Compatibility

Designed as an OEM-style plenum audio cable for use in low-voltage distributed audio and structured wiring systems requiring 18 AWG shielded plenum cable with drain wire.

Installation Notes

Installation must be performed by a licensed low-voltage or electrical contractor in accordance with NEC Article 800 and local building codes governing plenum-rated wiring. Confirm the ceiling or wall cavity classification before pulling cable, as plenum-rated jacket is required in any air-handling return space. Power down any connected audio equipment before terminating or splicing. Avoid sharp bend radii that can damage the shield foil and compromise interference rejection.
