Application
THW cables are widely used in the installation of building electrical systems, especially in residential, commercial and industrial buildings. Due to its moisture resistance and good insulation properties, THW cables are suitable for wiring inside buildings and can be used for power supply, lighting, electrical control systems, etc. According to UL 83 standards, THW cables can work stably in wet environments, making them ideal for wet and humid areas, especially underground cable laying and installation of wires in walls.

Feature

THW wire consists of a single or multiple conductors twisted together to form a conductor. The copper conductor ensures excellent conductivity and has strong corrosion resistance. The wire is insulated with a moisture-proof, flame-retardant, and sunlight-resistant PVC (polyvinyl chloride) sheath. The moisture-proof performance of the PVC insulation layer makes this wire suitable for installation in areas where the wire may be exposed to damp or humid environments. It has excellent performance in both indoor and outdoor applications, ensuring safety, durability, and long-lasting functionality.
Certification
THW cables are UL certified and meet a range of safety and performance standards from Underwriters Laboratories (UL). UL certification means that the cable has been rigorously tested to ensure reliable performance and safety under normal use conditions. In particular, THW cables meet UL 83, a basic requirement for cables covering conductors, insulation materials, sheaths, and other aspects to ensure durability and safety of the cable in normal environments.
