Premium THHN/THWN-2 Electrical Building Wire – Single Core Stranded Copper PVC/Nylon Insulated Conduit Wire (600V)
Premium THHN/THWN-2 Electrical Building Wire – Single Core Stranded Copper PVC/Nylon Insulated Conduit Wire (600V)
Pull high-efficiency power and branch circuits through conduits with our Premium THHN/THWN-2 Electrical Building Wire. Engineered for branch circuits, indoor lighting, socket outlets, sub-panel feeds, and industrial control systems, this single-core building wire features a high-grade annealed stranded copper conductor protected by flame-retardant PVC insulation and a tough outer nylon jacket.
Rated for dual THHN (dry locations up to 90°C) and THWN-2 (wet or damp locations up to 90°C) performance, the slick outer nylon coat drastically reduces pulling friction inside PVC and steel (EMT) conduits without requiring excessive wire-pulling lubricants. Built to strict SASO, SEC, UL 83, and NEC standards, this wire delivers superior resistance against heat, moisture, abrasion, oil, and gasoline in residential villas, commercial towers, and industrial facilities.
Key Features
-
Dual THHN / THWN-2 Performance: Fully rated for 90°C operating temperatures in both dry and wet/damp conduit environments.
-
Slick Nylon Outer Jacket: Tough polyamide (nylon) coating provides exceptional abrasion and chemical resistance while enabling smooth, low-friction conduit pulling.
-
99.9% High-Conductivity Annealed Copper: Class 2 stranded copper core ensures low electrical resistance, minimal voltage drop, and high mechanical flexibility.
-
SASO & SEC Compliant: Manufactured to strictly meet Saudi Arabian building codes and electricity authority standards for maximum safety and project approval.
-
Color-Coded Phase Identification: Available in all standard SASO/SEC phase, neutral, and earth grounding colors for clear, error-free panel wiring.
