In medium- and high-voltage power cable manufacturing, achieving reliable electromagnetic interference (EMI) shielding while delivering long-term moisture and chemical protection is essential for cable longevity and system reliability. Copolymer Coated Copper Tape<\/strong><\/a> \u2014 also known as EAA Coated Copper Tape or Copolymer Copper Shielding Tape \u2014 is a high-performance composite material engineered specifically for these demanding applications.<\/p>\n

This advanced shielding tape consists of a high-conductivity, soft-annealed copper substrate uniformly coated on one or both sides with a specialized ethylene acrylic acid (EAA) copolymer layer, typically color-coded green for quick visual identification during production and quality inspection. The EAA coating provides exceptional adhesion to common jacketing resins (PE, LLDPE, HDPE, or low-smoke zero-halogen compounds), enabling robust \u201cbonded jacket\u201d or laminated sheath constructions that resist delamination under thermal cycling, mechanical stress, or prolonged exposure to water and chemicals.<\/p>\n

As a trusted B2B cable materials supplier with extensive experience supporting global MV\/HV cable producers, we recognize this tape as a critical component that enhances both electrical performance and environmental durability in underground, submarine, aerial, and industrial installations.<\/p>\n

\"Copolymer<\/p>\n

Composition & Advanced Structure<\/h2>\n

The tape features:<\/p>\n

    \n
  • Soft-annealed high-purity copper base<\/strong> (thickness 0.10\u20130.20 mm) \u2014 delivering \u226590% IACS conductivity for superior shielding and fault-current handling.<\/li>\n
  • EAA copolymer coating<\/strong> (\u22480.05 mm per side) \u2014 applied uniformly on one or both sides. The green-tinted layer ensures low bonding temperature, high heat-seal performance, and excellent chemical compatibility with extruded jackets.<\/li>\n<\/ul>\n

    This structure creates a permanent, non-delaminating bond between the copper and the polymer, while forming a strong polymeric interface with the outer sheath during high-speed extrusion. The result is a seamless, high-peel-strength laminated shield that prevents water migration and corrosion far more effectively than bare copper tape.<\/p>\n

    Ba\u015fl\u0131ca Teknik Avantajlar ve Performans Faydalar\u0131<\/h2>\n

    Outstanding Electromagnetic Shielding & Conductivity<\/strong> With \u226590% IACS conductivity, the copper core provides excellent EMI\/RFI protection and serves as an effective electrostatic screen. It also contributes to fault-current carrying capacity, helping maintain system safety during short-circuit events.<\/p>\n

    Superior Moisture & Chemical Barrier<\/strong> The EAA copolymer creates a high-integrity barrier with proven long-term performance. In standardized tests (168 hours at 68\u00b0C in filler\/flood or water), it achieves Grade 7 corrosion resistance<\/strong> with no delamination and maintains peel strength \u22655 N\/cm \u2014 critical for wet or chemically aggressive environments such as underground ducts, coastal areas, or offshore applications.<\/p>\n

    Exceptional Adhesion & Processability<\/strong><\/p>\n

      \n
    • Peel strength: \u22655 N\/cm<\/li>\n
    • Heat seal strength: \u226517.5 N\/cm<\/li>\n
    • Tensile strength: \u2265180 MPa<\/li>\n
    • Elongation at break: \u226515%<\/li>\n<\/ul>\n

      These properties allow easy longitudinal or helical application on high-speed cabling lines without wrinkling, cracking, or separation. The lower bonding temperature of EAA simplifies production and improves overall manufacturing efficiency compared to traditional coatings.<\/p>\n

      Mechanical Durability & Dielectric Integrity<\/strong> The tape withstands the rigors of cable processing, installation, and service life. Two-side coated versions exhibit no dielectric breakdown at DC 1 kV<\/strong>, preserving insulation integrity across the sheath interface.<\/p>\n

      Customization for Specific Cable Designs<\/strong> Available in a wide range of widths (10\u20131000 mm), inner diameters (76 mm, 102 mm, 150 mm, 406 mm), and joint-free outer diameters up to 1000 mm, the tape can be precisely matched to your cable diameter, armor type, or sheath configuration.<\/p>\n

      Primary Applications in Power Cable Systems<\/h3>\n

      Copolymer Coated Copper Tape is widely specified for:<\/p>\n

        \n
      • Orta ve Y\u00fcksek Gerilim G\u00fc\u00e7 Kablolar\u0131 (OG\/YG)<\/strong>: As a combined shielding layer and moisture\/chemical barrier around the insulated core.<\/li>\n
      • Underground & Direct-Buried Cables<\/strong>: Essential water-blocking and corrosion protection in moist or chemically aggressive soils.<\/li>\n
      • Submarine & Offshore Cables<\/strong>: Enhanced saline and chemical resistance when integrated with metallic sheaths or armoring.<\/li>\n
      • Aerial & Laminated Sheath Designs<\/strong>: Strong bonding to PE\/LLDPE jackets for \u201cbonded jacket\u201d constructions that resist mechanical stress, UV, and environmental exposure.<\/li>\n
      • Specialized Cables<\/strong>: Including those requiring compliance with water penetration tests, oil\/chemical resistance, and long-term dielectric stability in industrial or renewable energy projects.<\/li>\n<\/ul>\n

        It is frequently used in longitudinally corrugated (LC) shield designs or in combination with other metallic barriers to achieve comprehensive radial and longitudinal protection.<\/p>\n

        Why Copolymer Coated Copper Tape Outperforms Alternatives<\/h3>\n

        Compared to bare copper tape or standard foil shields, the EAA copolymer coating eliminates common failure modes such as delamination under thermal cycling, poor jacket bonding, and accelerated corrosion in humid or saline conditions. It offers superior peel strength, chemical resistance, and production-friendly heat-seal performance while retaining full conductivity \u2014 making it the preferred upgrade for modern bonded-jacket or fully water-blocked MV\/HV cable designs.<\/p>\n

        Reliable Shielding & Long-Term Protection for Critical Infrastructure<\/h3>\n

        Copolymer Coated Copper Tape combines the proven electrical performance of high-purity copper with the advanced moisture-barrier and adhesion properties of EAA copolymer technology. The result is a technically superior, process-efficient material that enhances cable reliability, simplifies manufacturing, and reduces long-term maintenance costs in the most demanding power transmission and distribution environments.<\/p>\n
