22 AWG Twisted Pair Shielded Cable (14C, 32ft)
Premium Conductivity: The core uses 99.99% oxygen-free copper, delivering low resistance for stable signal transmission and reduced heat generation. This supports clean audio and data lines, especially where long runs might otherwise degrade quality.
Enhanced Shielding: A dual-layer shield combines an aluminum foil layer with a dense copper braided net. This structure minimizes EMI and RFI, helping preserve signal clarity in electrically noisy environments such as industrial spaces or near motor drives.
Flame Retardant & Safe: The outer sheath and inner insulation employ flame-retardant PVC, making the cable self-extinguishing and safer for installations in areas with strict fire-safety requirements. The jacket also minimizes odor and avoids smoke in event of accidental exposure to heat.
4-Core Twisted Pair Shielded Cable (18AWG)
Premium Conductivity: 99.99% OFC copper ensures low resistance and efficient signal transfer with minimal heat, supporting stable operation in control and communication lines.
Enhanced Shielding: The cable uses a dual-layer shield (aluminum foil plus copper braid) to cut down EMI/RFI, maintaining signal integrity in environments with high electrical noise.
Flame Retardant & Safe: The flame-retardant PVC jacket and insulation reduce ignition risk and odor, suitable for installations in enclosed spaces or where fire safety is a concern.
20 AWG Twisted Pair Shielded Cable (34C, 65 ft)
Premium Conductivity: The OFC copper core delivers low resistance and reliable signal propagation with minimal heating, supporting consistent performance over longer cable runs.
Enhanced Shielding: A dual-layer shield (aluminum foil + copper braid) offers strong EMI/RFI suppression, maintaining clean signals for audio, sensing, or data lines in challenging installations.
Flame Retardant & Safe: New flame-retardant PVC materials provide a safer, self-extinguishing jacket and insulation, with low odor characteristics during operation and installation.
20/18/16/14/12 AWG Shielded Cable (98 ft, 12AWG)
Premium Conductivity: The 99.99% OFC copper core provides low resistance and steady performance across multiple conductors, suited for complex control panels or multi-channel installations.
Enhanced Shielding: The combination of aluminum foil and copper braided shielding minimizes EMI and RFI, yielding high signal integrity in environments with electrical interference.
Flame Retardant & Safe: The outer sheath and inner insulation use flame-retardant PVC to improve safety and reduce odor, a practical choice for long runs and bulk cable deployments.
20 AWG Shielded Cable (14C, 65 ft)
Premium Conductivity: The 99.99% OFC copper core ensures low resistance and efficient signal flow, supporting reliable operation in automation and control circuits.
Enhanced Shielding: A dual-layer shield with aluminum foil and copper braid suppresses EMI/RFI, sustaining signal clarity for critical sensing and data tasks.
Flame Retardant & Safe: Flame-retardant PVC jackets reduce fire risks and odors, improving safety for installations in tight spaces or near heat sources.
ZGOVIRLEN Twisted Pair Shielded Cable (18-26 AWG, 2–8 Core)

Buying Guide: Key Purchase Considerations And Comparisons
Selecting the right 14 AWG shielded twisted pair cable involves balancing electrical performance, safety, and installation practicality. The following considerations help buyers compare options across the five highlighted products.
- Conductor material: All featured products use high-purity copper (OFC or tinned copper). OFC offers excellent conductivity and lower resistance, while tinned copper adds corrosion resistance for moist or outdoor environments.
- Shielding structure: A dual-layer shield (aluminum foil plus copper braid) is common and effective for EMI/RFI suppression. Some variants use alternative shielding configurations; evaluate expected interference in your installation area.
- Outer jacket material: Flame-retardant PVC provides safety advantages and odor control. If your application requires chemical resistance or higher heat tolerance, verify jacket specifications.
- Conductor count and gauge: 14 AWG is a robust choice for power and signaling. If you need multiple signaling lines or a specific core count, select a multi-core option that fits the required channel count.
- Length and flexibility: Longer runs can introduce resistance and attenuation. Consider the maximum recommended length for your device, and choose a flexible jacket if routing through tight spaces or conduits.
- Termination and compatibility: Some cables are more welding-friendly or easier to terminate with common connectors. Check for compatibility with your crimping tools or soldering practices.
- Safety certifications and standards: Look for UL listings or other safety certifications if your installation requires formal compliance, especially in industrial or commercial environments.
Across these options, the primary differentiators are shielding efficiency, conductor purity, and jacket safety. For installations near motors, drives, or high-frequency equipment, prioritize cables with robust shielding and OFC copper. For extended runs in corrosive or outdoor settings, consider tinned copper variants and additional protective jackets. Always ensure the chosen cable meets your local electrical codes and installation requirements.
