The N2XRY armored cable is a high-performance power cable designed for complex energy transmission scenarios, whose structural design and material selection fully meet the stringent requirements for safety, durability, and efficiency in industrial, municipal, and energy sectors. The designation "N2XRY" directly reflects its core composition and performance characteristics, where "N" denotes fire resistance, "2" indicates suitability for higher temperature environments, "X" refers to cross-linked polyethylene (XLPE) insulation, "R" corresponds to polyvinyl chloride (PVC) sheathing, and "Y" implies the flexibility and adaptability of its overall structure. Structurally, the N2XRY cable features a multi-layer composite design. The core conductor is made of high-purity copper (CU), which exhibits excellent electrical conductivity, effectively reducing energy loss during transmission and ensuring efficient power delivery. The conductor is wrapped in a cross-linked polyethylene (XLPE) insulation layer, a material known for its high voltage resistance, aging resistance, and temperature tolerance. It can operate stably in environments ranging from -40°C to 90°C, significantly enhancing the cable's insulation reliability and preventing safety hazards such as short circuits and leakage. To further enhance the cable's mechanical protection, a steel wire armor (SWA) structure is applied over the XLPE insulation. The steel wire armor, either spirally wound or longitudinally wrapped, provides robust resistance to impact, extrusion, and stretching. This allows the cable to withstand external pressures from underground laying, burial projects, or vibrations from industrial equipment, while also effectively resisting gnawing by rodents, thereby extending the cable's service life. Externally, the armor layer is covered with a polyvinyl chloride (PVC) outer sheath. PVC not only offers excellent corrosion resistance, protecting against chemicals, moisture, and ultraviolet radiation in the soil, but also provides a degree of flame retardancy, complying with fire safety standards. It is particularly suitable for industrial environments with humidity, dust, or flammable risks. The N2XRY cable finds extensive applications, including urban power grid transformation, industrial park distribution systems, power transmission in high-rise buildings, and grid-connection lines of new energy power stations (e.g., photovoltaic and wind power). In these scenarios, the cable must cope with complex environmental conditions and high-load power transmission demands. With its multi-layer protective structure and high-performance material combination, N2XRY stably ensures continuous power supply and reduces maintenance costs. Moreover, the cable is designed for easy installation. The flexibility of the steel armor allows for easy bending and laying, reducing construction difficulties. Additionally, its standardized specifications (with cross-sectional areas ranging from 10mm² to 400mm²) can meet transmission needs of different power levels, adapting to various wiring equipment. In summary, the N2XRY armored cable achieves a comprehensive balance of conductivity, insulation safety, mechanical protection, and environmental adaptability through the scientific combination of copper conductors, XLPE insulation, steel armor, and PVC sheathing. It is an ideal choice in modern energy transmission, offering both reliability and cost-effectiveness

Xtmu Cable is a 600V power cable compliant with ICEA S-95-658 standard, featuring a four-layer structure of copper (Cu) conductor, XLPE (cross-linked polyethylene) insulation, inner PVC (polyvinyl chloride) sheath, and outer PVC sheath (Cu/XLPE/PVC/PVC). It integrates multiple advantages such as high-efficiency conductivity, heat resistance stability, mechanical protection, and environmental adaptability, widely used in industrial, commercial, and civil low-voltage distribution systems.​ In terms of structure, the cable uses high-purity copper as the conductor with a purity of over 99.95%. After multi-strand stranding, it not only has excellent conductivity (conductivity ≥58MS/m) but also good flexibility, facilitating laying in complex environments. The conductor is wrapped with an XLPE insulation layer, which forms a three-dimensional network molecular structure through cross-linking reaction. It allows a long-term operating temperature of up to 90°C and can withstand 250°C during short circuits (within 5 seconds), effectively preventing insulation aging due to overheating. Outside the XLPE insulation is an inner PVC sheath, mainly playing a buffering and isolating role to protect the insulation layer from extrusion damage by the outer sheath; the outermost layer is an outer PVC sheath, added with flame retardants, antioxidants, and UV stabilizers. It has properties such as wear resistance, corrosion resistance, and UV resistance, capable of resisting mechanical impact, moisture, chemicals, and direct sunlight, providing double sheath protection for the cable.​ In terms of performance parameters, the cable has a rated voltage of 600V, suitable for low-voltage distribution systems with AC 50Hz/60Hz, and meets the strict requirements of ICEA S-95-658 standard for insulation resistance, dielectric loss, flame retardancy, and other indicators. Its insulation resistance is ≥1000MΩ·km, and the dielectric loss tangent (tanδ) is ≤0.005, ensuring extremely low energy loss during power transmission. The current-carrying capacity varies with conductor specifications. Taking common 10AWG to 4/0AWG as examples, the current-carrying capacity ranges from 40A to 210A when laid in air, meeting the power needs from small and medium-sized equipment to medium industrial loads. In terms of mechanical properties, the minimum bending radius of the cable is 10 times the outer diameter (for fixed laying), adapting to installation in narrow spaces; the outer PVC sheath has a tensile strength of ≥12MPa and an elongation of ≥150%, withstanding stretching, extrusion, and friction during laying.​ In application scenarios, Xtmu Cable, with the enhanced protection of double PVC sheaths, performs well in various environments: in industrial fields, it is often used for power distribution of motors and control cabinets in factory workshops, resisting oil pollution and dust erosion; in commercial buildings, as the main line of lighting and air conditioning systems in shopping malls and hotels, its flame retardancy meets the safety requirements of public places; in civil scenarios, it is suitable for damp areas such as strong electric wells and underground garages in high-rise buildings, and the inner PVC sheath can further block moisture to protect the XLPE insulation layer. In addition, as it complies with ICEA S-95-658 standard, the cable can also be used in low-voltage distribution projects in North America and other regions, adapting to international engineering needs.​ In terms of installation and maintenance, the cable supports various laying methods such as 桥架，pipe laying, and direct burial. During installation, excessive bending or contact with sharp objects should be avoided to prevent sheath damage. Terminal connections require copper joints of appropriate specifications, ensuring good conductivity through crimping, and 做好密封处理 to prevent moisture intrusion. After laying, insulation resistance testing and voltage withstand testing (applying 2.5 times the rated voltage for 5 minutes without breakdown) must be conducted to verify performance compliance. In daily maintenance, regularly check whether the outer sheath has cracks, bulges, or signs of aging, and repair in time if problems are found; for cables exposed to sunlight, sunshades can be added to delay sheath aging and extend service life.​ In summary, Xtmu Cable (600V, Cu/XLPE/PVC/PVC), through the collaborative design of copper conductor, XLPE insulation, and double PVC sheaths, achieves a balance of efficient transmission, safety protection, and environmental adaptability while meeting ICEA S-95-658 standard. It is a preferred cable with both reliability and compliance in low-voltage distribution systems, providing stable guarantee for various power transmission scenarios.
