The 0.6/1kv aluminum XLPE power cables of models Na2xy, Na2xh, Nayy-O, Lxv, etc., involved in this article include various specifications such as 1X300mm², 1X400mm², 1X500mm², and 1X630mm². With excellent performance and wide applicability, they occupy an important position in the field of low-voltage power transmission.​ In terms of specification parameters, these cables are all single-core structure, and the number after "1X" represents the cross-sectional area of the conductor, which are 300mm², 400mm², 500mm², and 630mm² respectively. The cross-sectional area of the conductor is a key factor determining the current-carrying capacity of the cable; the larger the cross-sectional area, the higher the current-carrying capacity. At an ambient temperature of 25℃, the long-term allowable current-carrying capacity of the 1X300mm² cable is about 420A, which can meet the power transmission needs of power around 92kW; the long-term allowable current-carrying capacity of the 1X400mm² cable is about 500A, which can cope with the power consumption scenarios with power around 110kW; the long-term allowable current-carrying capacity of the 1X500mm² cable is about 580A, suitable for power transmission with power around 128kW; the long-term allowable current-carrying capacity of the 1X630mm² cable can reach 680A, which can meet the power demand of high-power equipment with power above 149kW. At the same time, the rated voltage of these cables is 0.6/1kv, which is suitable for low-voltage power systems and can stably transmit power.​ In terms of materials, the conductor is made of high-purity aluminum. Aluminum has good conductivity. Although its conductivity is slightly lower than that of copper, its price is relatively low, which can reduce costs while ensuring transmission efficiency. The aluminum conductor has undergone special treatment, with good oxidation resistance and corrosion resistance, and can work stably for a long time in various environments. The insulation layer is made of XLPE (cross-linked polyethylene) material. XLPE has excellent electrical performance, with high insulation resistance and good corona resistance, which can effectively prevent leakage and improve the safety performance of the cable. Its temperature resistance is excellent, and it can operate for a long time at a working temperature of 90℃, with a short-term overload temperature of up to 130℃, adapting to the possible temperature changes during power transmission. In addition, XLPE also has good mechanical strength and aging resistance, which prolongs the service life of the cable.​ These cables have a wide range of characteristic uses. In the industrial field, 1X500mm² and 1X630mm² cables can be used for power supply of large industrial equipment, such as large motors and compressors, ensuring the stable operation of high-power equipment; 1X300mm² and 1X400mm² cables are suitable for small and medium-sized industrial equipment, workshop power distribution systems, etc., providing power support for the normal operation of production lines. In urban distribution networks, they can be used for power transmission between substations and residential communities and commercial facilities. Appropriate specifications are selected according to the power load to ensure stable power supply. In construction projects, 1X300mm² and 1X400mm² cables are often used as power distribution trunks in buildings, transmitting power from the distribution room to each floor to meet the power demand inside the building.​ In addition, this series of cables also has significant cost advantages. Due to the use of aluminum as the conductor material, compared with copper-core cables, the cost is lower, which can save a lot of funds for engineering projects. At the same time, its excellent performance and various specifications make it possible to find suitable options in different power transmission scenarios, improving the cost performance of the project.​ To sum up, the 0.6/1kv aluminum XLPE power cables of models Na2xy, Na2xh, Nayy-O, Lxv, etc., with their various specifications, excellent materials, outstanding performance and economic cost, have become ideal choices in the field of low-voltage power transmission, providing reliable power transmission guarantee for various power projects.
