120mm² 150mm 250mm² 325mm² Copper Aluminum Wire 500 650 MCM Kcmil THHN/THWN-2 600V Stranded Cable PVC Insulation for Heating Product Abstract​ High-Power Cables for Heavy-Duty Heating Applications​ Designed for high-demand heating systems, our 120mm², 150mm², 250mm², 325mm² copper and aluminum wires, along with 500 and 650 MCM (Kcmil) options, feature THHN/THWN-2 insulation and a 600V rating. These stranded cables with PVC insulation deliver exceptional performance in industrial and large-scale commercial heating environments.​ Robust Conductors & Construction​ The cables utilize high-quality copper and aluminum conductors, balancing conductivity and cost-effectiveness. Copper ensures superior electrical efficiency, ideal for critical heating setups, while aluminum offers a lightweight, economical alternative for heavy loads. The stranded design enhances flexibility, simplifying installation in complex industrial layouts, even when routing around large heating equipment or through confined spaces.​ THHN/THWN-2 Insulation Advantages​ PVC insulation with THHN/THWN-2 ratings provides outstanding heat and moisture resistance. THHN excels in dry, high-temperature areas like furnace rooms, while THWN-2 extends reliability to wet or damp environments, such as industrial boilers or outdoor heating systems. This dual compatibility ensures the cables withstand the extreme conditions of heavy-duty heating applications, preventing insulation degradation and ensuring long-term safety.​ Versatile Sizing for Heating Loads​ From 120mm² to 650 MCM, the range covers diverse heating needs. Smaller 120mm² and 150mm² cables suit medium industrial heaters, while 250mm², 325mm², 500 MCM, and 650 MCM options handle large-scale systems like industrial furnaces, thermal power units, and commercial central heating. Rated at 600V, they ensure stable power transmission, minimizing energy loss and maximizing heating efficiency.
