This product is a Na2xy type triple-core power cable (Cable De Energia Tripolar) with the specification of 3-1×240mm² and a rated voltage of 0.6/1kV, suitable for medium and low-voltage power distribution scenarios.​ "3-1×240mm²" indicates that the cable adopts a three-core independent structure with a single-core conductor cross-sectional area of 240mm², which can carry a large current (long-term allowable current-carrying capacity is about 400A at 25℃ ambient temperature). It can meet the high-power power transmission needs of large industrial equipment, building main distribution and other scenarios. The rated voltage of 0.6/1kV is compatible with low-voltage power grid standards and meets the voltage requirements of conventional power distribution systems.​ The cable usually uses copper as the conductor material, with excellent conductivity; the insulation layer and sheath are mostly made of temperature-resistant and corrosion-resistant polyvinyl chloride (PVC) or other suitable materials, which can operate stably in various environments such as dry and humid conditions. The three-core structure design facilitates three-phase power transmission and is suitable for industrial and civil three-phase power supply systems.​ It has a wide range of application scenarios, such as main power supply for factory production lines, main distribution lines of commercial complexes, and power distribution systems of high-rise buildings. It can meet the power supply needs of high-power equipment through the advantage of large cross-sectional area.
