The 120mm², 150mm², 185mm² copper core power cables with a rated voltage of 0.6/1kV adopt Freetox halogen-free insulation materials, covering structural types such as duplex, triplex and unipolar, with model N2xoh. They are suitable for power transmission scenarios with high requirements for environmental protection and safety.​ The conductor is made of high-purity copper, which has excellent conductivity and can efficiently transmit electricity to meet the power supply needs of different power equipment. The 120mm² is suitable for medium-sized industrial equipment and building distribution trunks; the 150mm² can be adapted to larger power motors and main lines of commercial complexes; the 185mm² is applicable to heavy-load scenarios such as large transformer connections and factory area main distribution.​ Freetox halogen-free materials endow the cable with environmental protection characteristics. It does not release toxic gases when burned, reducing the risk of fire, and is especially suitable for densely populated places such as hospitals, schools and subways. The duplex and triplex structures facilitate the laying of multi-phase circuits, while the unipolar cable is flexibly adapted to single-phase or DC systems, and can meet various installation methods such as direct burial, pipe threading and overhead.​ Overall, this series of cables combines high conductivity, halogen-free environmental protection and structural diversity, and is a power transmission solution that takes into account safety, efficiency and environmental friendliness.
