This series of cables includes Na2xry and Na2xrh models, which are 0.6-1kV aluminum core armored cables (SWA Cable), covering various specifications such as 4X25mm², 4X50mm², 4X70mm², 4X95mm², 4X120mm², 4X150mm² and 4X185mm².​ The cable uses an aluminum core as the conductor. The aluminum material has both good conductivity and lightweight advantages, which can ensure the efficiency of power transmission while reducing the load pressure during laying. The outer layer is equipped with a steel wire armored (SWA) structure, which significantly improves the mechanical strength, has tensile and wear resistance, can adapt to complex environments such as underground direct burial and bridge laying, and forms effective protection for the internal insulation layer.​ The rated voltage of 0.6-1kV makes it suitable for medium and low-voltage power systems, and the 4-core structure design meets the needs of multi-phase power transmission. Different cross-sectional area specifications cover various load scenarios: 4X25mm² to 4X70mm² are suitable for power supply of small and medium-sized equipment and building branch lines; 4X95mm² and above specifications can carry industrial-grade high-power equipment, and are widely used in power transmission in factory power distribution, municipal engineering, energy stations and other fields.​
