Copper Red Green Blue Red 3.5mm 5.5 Sqm 8mm² Stranded AC Electrical Wire Cable: 600V Rated PVC for Heating, THHN/THWN/THWN-2​ This versatile stranded AC electrical wire cable is engineered to excel in heating applications, combining robust performance with multi-standard compliance (THHN/THWN/THWN-2). Crafted with high-purity copper conductors, it features a cross-sectional area of 8mm² (5.5 sqm) and a 3.5mm diameter, ensuring efficient current transmission for heating systems requiring stable power delivery.​ Distinguished by its red, green, blue, and red color coding, the cable simplifies phase identification, critical for safe and accurate installation in complex electrical setups. The PVC insulation, rated for 600V, offers exceptional durability: resistant to heat, moisture, and chemicals, it thrives in harsh environments—from industrial heating units to commercial HVAC systems. THHN/THWN/THWN-2 certifications validate its suitability for both dry and wet locations, with temperature tolerance up to 90°C (dry) and 75°C (wet), making it ideal for proximity to heating elements.​ The stranded design enhances flexibility, easing installation in tight spaces or around corners without compromising structural integrity. Whether integrated into radiant heating, furnace wiring, or duct heaters, this cable balances conductivity, safety, and longevity, making it a top choice for contractors and engineers prioritizing reliability in heating infrastructure.
