The core information of Na2xy 3×95 + 50mm² power cable is as follows:​ Specification and Structure: It adopts a 3 + 1 core design, with 3 main cores with a cross - sectional area of 95mm² and 1 neutral core with 50mm². It is suitable for three - phase power supply systems. The main cores are responsible for power transmission, and the neutral core balances the current. The compact structure is suitable for underground laying.​ Material and Performance: There are two conductor options: copper and aluminum. Copper conductors have excellent conductivity and low loss; aluminum conductors are lightweight and low - cost. The insulation layer is XLPE, which has strong temperature resistance and insulation performance and can resist temperature changes in the underground environment. The sheath is made of PVC, which has moisture - proof, corrosion - resistant and mechanical protection functions and is suitable for underground humid and friction - prone environments.​ Application Scenarios: Designed specifically for underground laying, it is suitable for scenarios such as underground power distribution trunk lines in residential communities and underground transmission lines in small and medium - sized industrial plants. It can meet the power transmission needs of small and medium - sized electricity - using areas and operate stably in underground environments such as soil pressure and water vapor erosion.​ This cable balances performance and environmental adaptability. The choice of copper and aluminum conductors is flexible, making it a practical choice for underground low - voltage power distribution.
