Cable conductor blindado enrollado en tira de níquel puro
El cable conductor blindado envuelto en cinta de níquel puro es un cable de transmisión preciso diseñado para una protección enfocada contra interferencias electromagnéticas.. Su estructura central está estratificada de adentro hacia afuera.: el centro es un conductor de cobre de alta pureza (hecho principalmente de cobre libre de oxígeno para garantizar la eficiencia de transmisión actual), la capa exterior del conductor está envuelta con una capa aislante resistente a la temperatura (comúnmente hecho de politetrafluoroetileno, polietileno reticulado, etc.), la capa exterior de la capa aislante está enrollada en espiral con cinta continua de níquel puro en un paso específico para formar una capa protectora, y la capa más externa está cubierta con una funda protectora (como PVC, fluoroplásticos, etc., para mejorar la protección mecánica). La cinta de níquel puro utilizada aquí está hecha de níquel de alta calidad con una pureza de ≥ 99.6%, Procesado mediante laminado y recocido precisos.. El espesor se controla entre 0,03-0,1 mm., y la tasa de cobertura de bobinado puede alcanzar 90%-95%, asegurando la integridad del blindaje.
Outstanding shielding performance: Pure nickel tape possesses excellent magnetic shielding and electromagnetic shielding capabilities. Compared to traditional copper tape and aluminum foil shielding, it has a stronger attenuation ability for electromagnetic signals ranging from low frequency to high frequency (1kHz – 1GHz). It can effectively prevent external electromagnetic radiation from interfering with the signal of the conductor and prevent the leakage of the conductor’s own signal, ensuring the purity of the transmitted signal.
Strong environmental stability: Pure nickel material has excellent resistance to high temperatures (long-term working temperature can reach 200-400℃, adjusted according to the sheath material), low temperatures (-60℃ or below can work stably), and corrosion resistance. It can resist the erosion of humid, acidic, alkaline media, salt fog, etc., is not prone to oxidation and aging, and extends the lifespan of the wire.
Excellent mechanical properties: The pure nickel tape has a tight winding structure and certain flexibility. During winding, it is not prone to breaking or wrinkling. The wire can adapt to bending, twisting, etc.. installation scenarios. Al mismo tiempo, the bonding degree between the shielding layer and the insulation layer, the sheath is high, and its tensile strength and wear resistance are superior to ordinary wrapped shielding wire.
Good compatibility: The shielding layer is a good conductor and can be directly used as a grounding wire, simplifying the wiring structure. It has strong adaptability to different insulating and sheath materials and can customize the conductor cross-section (0.5 – 10mm²), winding pitch, and sheath color according to the application scenario to meet diverse needs.
Signal protection: In precision electronic equipment, instruments, and communication systems, it can block electromagnetic interference (EMI) generated by motors, frequency converters, and radio frequency equipment, preventing signal distortion and errors, ensuring the accuracy and stability of data transmission. Por ejemplo, in medical equipment, it can ensure the precise collection of detection signals.
Security guarantee: The shielding layer can limit the electromagnetic radiation leakage from conductors within a specified range, reducing the radiation impact on surrounding sensitive components and the human body. Al mismo tiempo, it can assist in guiding current during circuit short circuits, enhancing the safety of equipment power usage.
Environmental adaptability: In extreme conditions such as high temperatures, low temperatures, humidity, and corrosion (such as in aerospace, industrial automation, and new energy equipment), it can protect the internal conductors from environmental damage, maintain the transmission performance of the wires, and ensure the continuous and stable operation of the equipment.
Lengthen equipment lifespan: By reducing the loss of equipment internal components due to electromagnetic interference, lowering the occurrence rate of equipment failures, and indirectly extending the lifespan of the entire system, it also reduces maintenance costs.
