MOOKEERF 18/8 Shielded Wire 18 AWG 8 Conductor
18 AWG shielded cable with 8 conductors, designed for low-voltage wiring in security, alarm, and access control applications. The copper conductors are stranded for flexibility and better conductivity. The CMP plenum-rated jacket adds flame retardancy and safety for air-handling spaces. This model supports voltages up to 300V and handles temperatures from -10°C to 90°C, making it suitable for indoor installations, including ceiling runs and wallways in compliant environments.
Key features include pure copper strands for higher conductivity and corrosion resistance relative to copper-clad aluminum. Its 200 ft length allows longer runs between panels and devices, reducing splices. The jacket’s plenum rating helps meet safety requirements where air ducts are present, offering peace of mind in case of fire scenarios.
22 Gauge Wire (22 AWG) 8 Conductor Shielded Cable
This 22 AWG cable comprises eight conductors with pure copper strands and a shielded construction that minimizes interference in speaker, control, and alarm wiring. The CL3P plenum jacket provides fire-resistance in air-handling spaces, aligning with NEC requirements for low-voltage applications. UL-listed, it is a reliable choice for residential and commercial installations seeking both safety and performance. The combination of shield and drain wire helps reduce noise on data and signaling lines while maintaining flexibility for routing through walls and ceilings.
18 Gauge 6 Conductor Shielded Wire
This 18 AWG shielded cable provides six conductors with tinned copper strands and a dual-shield design (aluminum + tinned copper). The tinned copper offers corrosion resistance and easier soldering, making it suitable for CNC, motor, or audio signaling in controlled environments. The UL-listed construction supports compliance with safety standards, and the shielding delivers robust interference protection for sensitive signals in proximity to motors, drives, or high-noise equipment.
MOOKEERF 18 Gauge 8 Conductor Shielded Wire 50 ft
This 50-foot 18 AWG shielded cable includes eight conductors with a plenum-rated CL3P jacket, designed for low-voltage installations such as LED lighting, burglar systems, fire detectors, and security stations. The stranded copper conductors promote better conductivity and flexibility, while the shield helps suppress electrical noise. The flame-retardant jacket adds safety in building spaces where fire performance is a priority, making it a practical option for commercial and multi-location deployments.
25 ft West Penn Wire 3271 – 8 Conductor 22 Gauge Shielded Cable
West Penn Wire offers USA-made 22 AWG shielded cable with eight conductors and a shielded overall jacket. The CMR-rated build is suitable for commercial spaces, with reliability for in-wall and ceiling runs. While not plenum-rated, the CMR jacket provides robust flame resistance for many interior applications. The 22 AWG size balances flexibility with adequate current-carrying capacity for low-voltage control and signaling wires in security systems and audio installs.
Buying Guide
Key considerations when selecting an 8-conductor shielded cable include conductor gauge, shielding, jacket rating, and installation environment. For security and alarm systems, prioritize shielded, twisted pair-like construction and a plenum-rated jacket if runs occur in air handling spaces. Niches to consider:
- Conductor gauge: 18 AWG provides higher current capacity and lower resistance than 22 AWG, but is stiffer and less flexible for tight runs.
- Shielding: Double shielding (aluminum + copper) offers superior interference rejection, ideal near motors or RF sources; single shielding may suit quieter environments.
- Jacket rating: CMP/CL3P plenum jackets are required in many commercial spaces; CL2/CMR jackets are alternatives for restricted areas or non-plenum zones.
- Temperature and voltage: Ensure the cable supports operating temperatures and voltages for the specific devices (e.g., sensors, alarm panels, LED drivers).
- UL/NEC compliance: UL-listed or NEC Article 800 compatibility adds assurance for safety and code adherence in residential or commercial builds.
- Length and installation path: Longer runs reduce joints but may introduce more signal loss. Plan routes through walls, ceilings, and conduit where applicable.
- Flexibility and installation ease: Stranded copper offers better flexibility than solid conductors, easing bending and routing in tight spaces.
In practice, select a cable with copper conductors, plenum-rated jacket when required, and robust shielding for environments with potential interference. Consider the compatibility with your devices—security panels, access controls, and audio systems often benefit from higher shielding and cleaner signal integrity.
