This series of cables includes N2xh, N2xh-J, and N2xh-O models, among which N2xh-O is black. With a core specification of 4×25mm² and a rated voltage of 0.6/1kV, they are high-performance power cables suitable for low-voltage power distribution scenarios.​ "4×25mm²" represents a four-core structure, with a single-core cross-sectional area of 25mm². The total conductor cross-sectional area is suitable for small and medium-power transmission. At an ambient temperature of 25°C, the long-term allowable current-carrying capacity is about 85A. Calculated according to the three-phase power formula, it can carry a load of about 45kW, meeting the power supply needs of small and medium-sized industrial equipment and building branches. The 0.6/1kV rated voltage complies with low-voltage standards and can be directly connected to 380V/220V systems.​ The conductor is made of high-purity electrolytic copper (copper content ≥99.95%), and the multi-strand stranded structure improves flexibility. The insulation layer is added with weather-resistant additives, which is resistant to ultraviolet aging and suitable for outdoor environments. The sheath is made of black wear-resistant material, and some models (such as N2xh-O) have waterproof performance. N2xh-J focuses on stability, and N2xh-O enhances outdoor weather resistance, widely used in municipal lighting, outdoor substation branches and other scenarios.
