Conn-air w181p-2040.5cg Shielded Stranded Plenum Wire 500ft

Product Description

The CONN-AIR w181p-2040.5cg is a shielded stranded plenum-rated wire supplied in a 500-foot spool. Plenum-rated cable is manufactured with low-smoke, flame-retardant jacketing that meets the requirements for installation in air-handling spaces, including return-air plenums and supply ducts. The stranded conductor construction provides flexibility during routing and termination, and the foil or braid shield reduces electromagnetic interference on signal-carrying runs. This wire is handled and installed by licensed HVAC technicians and low-voltage electricians working on commercial and residential systems.

This wire is suited for low-voltage control wiring applications in plenum air spaces where building and fire codes require CMP-rated cable. Typical uses include thermostat wiring, zone control wiring, building automation system signal runs, and sensor interconnects routed through or above drop ceilings and through HVAC ductwork cavities. The 500-foot spool length supports larger commercial installations or multiple residential jobs from a single package.

Key Features

• Plenum-rated (CMP) jacketing meets fire and smoke requirements for air-handling space installation
• Stranded conductor construction allows flexible routing through tight pathways and conduit
• Shielded design reduces electromagnetic and radio-frequency interference on signal runs
• 500-foot spool minimizes mid-run splices on longer commercial or multi-zone jobs

Compatibility

Designed for low-voltage control wiring applications requiring plenum-rated cable in HVAC, building automation, and zone control systems installed in air-handling spaces.

Installation Notes

Installation of plenum-rated cable in air-handling spaces must comply with NFPA 90A and applicable local building codes; verify CMP listing requirements with the authority having jurisdiction before roughing in. De-energize all control circuits and disconnect low-voltage transformer power before making terminations. Use appropriate low-voltage hand tools for stripping and terminating stranded conductors, and maintain minimum bend-radius requirements to preserve shield integrity. Shield drain wires should be grounded at one end only to prevent ground loops on sensitive signal circuits.
