143 products

Complete commercial, industrial, telecommunications, and general electrical wiring projects with THHN wire from Launch 3 Telecom. THHN conductors feature durable thermoplastic insulation with a nylon outer jacket, providing a smooth, abrasion-resistant surface that supports efficient pulling through approved conduit and raceway systems.

This collection brings solid and stranded THHN wire options together in one convenient location. Available conductor configurations, colors, and spool or cut-length options help contractors select wire for branch circuits, equipment connections, control wiring, grounding, and other code-compliant electrical applications. Color choices can also support conductor identification and organized installation practices without limiting future project requirements.

Browse stranded THHN wire for flexible conductors that are easier to route through bends and complex pathways. For applications where a firm, shape-retaining conductor is preferred, explore our solid THHN wire collection.

Always confirm conductor size, insulation ratings, installation environment, ampacity requirements, and applicable electrical codes before ordering. Launch 3 Telecom supplies THHN building wire for electricians, electrical contractors, telecommunications installers, maintenance teams, and infrastructure professionals completing new construction, system upgrades, equipment installations, and repair work.
