Laser marking of wires and cables uses a non-contact laser beam to permanently code the surface of the outer sheath. The marking content mainly includes core information such as specifications and models, manufacturers, certification marks, meter markings, and traceable QR codes. Laser marking has clear and firm handwriting, excellent wear resistance, oil resistance, weather resistance, and flame retardancy, ensuring that information is not erased in complex installation environments and long-term use. This technology eliminates the pollution and easy detachment problems of traditional ink coding, providing reliable data protection for power construction, product traceability, safety certification, and anti-counterfeiting. It is a key link in improving the quality and safety of cable products.
