NYCWY copper wire screen cable is a high-performance cable designed for complex electrical environments, combining excellent conductivity, reliable shielding effect, and wide specification adaptability to meet the needs of power transmission and signal control in various fields. The cross-sectional specifications of this series cover 25mm², 35mm², 50mm², 70mm², and 120mm², which can flexibly cope with power supply scenarios from small-to-medium power to medium-to-high power equipment, providing stable solutions for industrial automation, building power distribution, rail transit, and other fields. In terms of structural design, NYCWY cable uses high-purity electrolytic copper as the conductor material, ensuring low resistance characteristics and efficient conductivity, effectively reducing energy loss during power transmission. The outer layer of the conductor is wrapped with temperature-resistant insulating material, which has good aging resistance and chemical corrosion resistance, and can adapt to working environments from -40℃ to 90℃, ensuring the stability of the cable under harsh conditions. The shielding layer is one of the key features of NYCWY cable. It adopts a tightly braided copper wire structure with a shielding efficiency of over 90%, which can significantly reduce the impact of external electromagnetic interference (EMI) and radio frequency interference (RFI) on signal transmission. At the same time, it prevents the electromagnetic field generated by the cable itself from interfering with peripheral equipment, making it particularly suitable for scenarios with strict requirements on signal stability, such as precision instruments, communication systems, and automated control loops. In terms of mechanical properties, the cable has improved flexibility through optimized stranding technology, facilitating bending and laying in narrow spaces, while enhancing tensile and wear resistance, extending its service life. In addition, the cable complies with the International Electrotechnical Commission (IEC) and relevant national standards, and has passed multiple tests such as voltage resistance, insulation resistance, and flame retardancy, ensuring safety and reliability in long-term use. In terms of application fields, the 25mm² and 35mm² specifications are suitable for indoor lighting in buildings, power supply for small motors, and secondary control loops; the 50mm² and 70mm² specifications are commonly used in industrial production lines, connection of small and medium-sized transformers, and outdoor power distribution systems; the 120mm² specification can meet the needs of high-power scenarios such as large-scale equipment, main lines of high-rise buildings, and new energy charging piles. To sum up, NYCWY copper wire screen cable, with its excellent conductivity, reliable shielding effect, wide range of specifications, and stable environmental adaptability, has become an ideal choice for power and signal transmission in industrial, construction, communication, and other fields.
