This paper introduces the Freetox Halogen-Free N2xoh 0.6/1kV 3X120+1X70 multipolar cable, a power transmission cable designed for safety and environmental protection requirements. It features a four-core structure with 3 phase conductors of 120mm² and 1 neutral conductor of 70mm², with a rated voltage of 0.6/1kV, suitable for medium and low-voltage distribution systems.​ "Freetox Halogen-Free" indicates that the cable uses halogen-free materials for its insulation and sheath. When burned, it does not release toxic halogen gases (such as chlorine and bromine) and only produces a small amount of low-toxic smoke, which can effectively reduce casualties and equipment damage in fires, meeting high safety standards. The N2xoh model identifier further reflects its halogen-free properties and specific structural design, with good temperature resistance and mechanical strength.​ The cable conductor is made of high-purity copper, ensuring excellent electrical conductivity and reducing transmission losses. The four-core structure is compatible with three-phase four-wire distribution scenarios, meeting power feeding needs in industrial plants, commercial buildings, public facilities, etc., and is particularly suitable for environments with strict fire safety requirements such as hospitals, schools, and subways.​ With the core advantages of halogen-free environmental protection, safety and reliability, the cable provides stable power transmission while offering additional safety protection for crowded and sensitive areas, making it an ideal distribution solution that balances performance and environmental friendliness.
