The Nayy Nyy Nyy-J 4X95mm², 4X120mm² grounded electrical power cable is a key equipment suitable for low-voltage distribution systems. With a rated voltage of 0.6/1kV, it adopts PVC insulation and sheath, and is overall black, combining reliability and practicality, which can meet the power transmission needs of various scenarios.​ In terms of specification parameters, the cable mainly includes two core specifications: 4X95mm² and 4X120mm². 4X95mm² means the cable is composed of 4 conductors with a cross-sectional area of 95mm², and 4X120mm² is 4 conductors with 120mm², both including a dedicated grounding wire to ensure electrical safety. There are differences in current-carrying capacity between the two specifications. The 4X95mm² cable has a current-carrying capacity of about 200-250A, suitable for medium-power power transmission; the 4X120mm² cable can reach a current-carrying capacity of 250-300A, which can meet the power supply needs of higher-power equipment. The rated voltage of 0.6/1kV enables it to be widely used in low-voltage distribution networks, covering power distribution scenarios in industrial, civil, commercial and other fields.​ Material and structural design are its core advantages. The conductor is made of high-purity copper or aluminum (depending on the model). Copper conductors have excellent conductivity, low resistance and low energy loss; aluminum conductors have more advantages in cost and lightweight. Both materials can ensure stable current transmission. The insulation layer and sheath are made of PVC material. PVC has good insulation performance, wear resistance and chemical corrosion resistance, which can effectively resist the erosion of the external environment and protect the internal conductors from damage. The black sheath not only has good weather resistance, which can adapt to the outdoor environment exposed to sun and rain, but also can reduce light reflection and reduce the visual interference of the cable in the installation environment. At the same time, the design of the dedicated grounding wire strengthens the safety protection, which can quickly conduct current into the ground in case of equipment leakage or short circuit, avoiding electric shock accidents and equipment damage.​ In terms of characteristic applications, the cable performs well in industrial plants. The 4X120mm² specification can be used to connect large-scale production equipment and power distribution of production lines to ensure the stable operation of high-power equipment; the 4X95mm² is suitable for power supply of small and medium-sized equipment and workshop lighting systems. In commercial buildings, such as shopping malls and office buildings, the two specifications can be used for power distribution trunk lines of high-power equipment such as central air conditioners and elevators, and branch lines of ordinary lighting and office equipment respectively, meeting the electricity needs of different areas. In the civil field, the distribution systems of residential communities often use it for power distribution. From the distribution room to the building main switch, and then to the distribution boxes of each unit, it can be seen, ensuring the stable daily electricity consumption of residents. In addition, its weather resistance and safety can also be fully utilized in scenarios such as temporary power supply for municipal engineering and outdoor landscape lighting.​ During the production process, the cable strictly follows relevant standards. Every step, from conductor drawing and stranding to the extrusion molding of PVC insulation layer and sheath, is precisely controlled. Key indicators such as the uniformity of the insulation layer thickness and the tightness of the sheath are strictly tested to ensure that the product quality meets the standards. Overall, the Nayy Nyy Nyy-J series cables, with their reasonable specification design, reliable material performance and wide applicability, have become an ideal choice in the field of low-voltage power distribution.
