This is a 90°C rated, 600V THHN/THWN building wire with copper conductor, suitable for fixed wiring installations in both dry and damp locations. The cable meets UL standards and features heat, oil and moisture resistance.

Thw Cable 12 AWG 7-stranded copper wire is a high-performance wire specially designed for wet environments, with excellent performance in the field of electrical wiring. Its 12 AWG gauge corresponds to a cross-sectional size of approximately 3.31mm², and it adopts a 7-stranded high-purity copper conductor structure. This design not only endows the wire with excellent flexibility, enabling it to easily cope with complex laying environments such as wall pipe threading and underground wiring, but also enhances its mechanical strength, reducing damage caused by bending and pulling during construction and prolonging its service life.​ The rated voltage of this wire is 600V, which fully complies with the standards of low-voltage distribution systems and can meet the power supply needs of various electrical equipment. Whether it is air conditioners and water heaters in residences or small power equipment in commercial places, they can obtain stable power support through it. Its current-carrying capacity is excellent, and it can still maintain stable power transmission capacity in humid environments, which can effectively avoid overheating caused by overload and ensure the safe operation of the electrical system.​ The insulation layer is made of high-quality PVC material, which has excellent insulation performance with an insulation resistance of ≥100MΩ·km. It can effectively block current and prevent leakage and short-circuit accidents. At the same time, PVC material also has good moisture resistance and chemical corrosion resistance. Even in humid, dusty environments or environments with slight chemical substances, it can maintain a stable insulation effect, ensuring the long-term reliable operation of the wire.​ This wire has passed UL 83 certification, which indicates that it meets strict international standards in terms of safety and performance, and is especially suitable for wet places, such as bathrooms, kitchens, basements, outdoor open areas, and wet workshops in industrial plants. The conventional 100-meter roll design is convenient for construction personnel to take and manage, reducing the number of wiring connections and improving construction efficiency.​ Whether it is wiring in wet areas of residential buildings, connection of outdoor electrical facilities in commercial places, or power supply in wet scenarios in industrial environments, Thw Cable 12 AWG 7-stranded copper wire can rely on its excellent moisture resistance, stable conductivity and reliable safety guarantee to become an ideal choice for electrical wiring, providing continuous and safe power transmission for electrical systems in various wet environments.
