In medium- and high-voltage cable manufacturing, effective electromagnetic interference (EMI) shielding combined with high electrical conductivity is essential for signal stability, fault current handling, and overall system reliability. Copper Tape for Cable<\/strong> \u2014 also known as Copper Foil Tape<\/strong> ou Soft-Annealed Copper Shielding Tape<\/strong> \u2014 is a high-purity, precision-slit copper foil engineered specifically for the cable industry. Produced from 99.9%+ pure electrolytic tough pitch (ETP) copper and soft-annealed to O temper, it delivers near-100% IACS conductivity, excellent formability, and superior mechanical properties for longitudinal or helical wrapping applications.<\/p>\n

As a trusted B2B supplier of complete cable materials and technical solutions with decades of global project experience, we recognize copper tape as the premium choice for manufacturers requiring maximum shielding effectiveness, fault-current capacity, and long-term durability in power cables, XLPE-insulated cables, transformers, and busway systems.<\/p>\n

Composition & Engineered Manufacturing Process<\/h3>\n

Copper Tape for Cable is manufactured from high-purity copper strip that undergoes precision cold rolling, annealing, and slitting. Key characteristics include:<\/p>\n

    \n
  • Base material<\/strong>: Electrolytic tough pitch (ETP) copper with \u226599.9% purity<\/li>\n
  • Temper<\/strong>: Soft-annealed (O temper) for maximum flexibility and wrapability<\/li>\n
  • Surface finish<\/strong>: Bright, clean, and burr-free edges for smooth high-speed processing<\/li>\n<\/ul>\n

    The tape is available in thicknesses from 0.05 mm to 0.20 mm and widths from 10 mm to 1000 mm, with optional adhesive backing or copolymer coating for enhanced bonding and moisture resistance.<\/p>\n

    Principaux avantages techniques et gains de performance<\/h3>\n

    Near-100% IACS Electrical Conductivity<\/strong> Copper tape provides the highest conductivity among common shielding materials, enabling excellent EMI\/RFI attenuation and low transfer impedance \u2014 critical for maintaining signal integrity in sensitive power and communication cables.<\/p>\n

    Superior Formability & High-Speed Processability<\/strong> Soft-annealed temper combined with high elongation ensures wrinkle-free longitudinal or helical wrapping on high-speed lines without cracking or spring-back, reducing production defects and scrap rates.<\/p>\n

    Excellent EMI Shielding & Fault-Current Capacity<\/strong> The high-purity copper core delivers near-100% optical coverage and high fault-current carrying capability, making it ideal for metallic shielding layers in MV\/HV cables and grounding applications in transformers and busway systems.<\/p>\n

    Mechanical Strength & Durability<\/strong><\/p>\n

      \n
    • Tensile strength: High (typically 200\u2013300 MPa in annealed condition)<\/li>\n
    • Elongation: Excellent (\u226530\u201345%)<\/li>\n<\/ul>\n

      These properties ensure the tape withstands mechanical stresses during manufacturing, installation, and service life.<\/p>\n

      Versatile & Customizable<\/strong> Available in bare, adhesive-backed, or copolymer-coated versions to suit different cable designs, with custom widths and thicknesses for precise matching to your production equipment and performance requirements.<\/p>\n
