Description

Copper Tape, also known as Copper Foil, is a high-purity, soft-annealed copper tape engineered for electromagnetic shielding and conductivity in power cables, transformers, and busway systems. With excellent electrical conductivity, superior formability, and reliable mechanical properties, it serves as an effective shielding layer that blocks electromagnetic interference (EMI) while protecting signal integrity in medium- and high-voltage cables.

Copper Wire Shielding or Copper Tape Shielding

Main Applications

Copper Tape is widely used as:

  • Shielding layer in power cables to prevent electromagnetic interference and ensure stable signal transmission.
  • Conductive component in transformers and busway systems for grounding, windings, and current-carrying layers.
  • Other electrical applications requiring high conductivity, flexibility, and EMI protection.

Its versatility makes it an essential material in modern cable manufacturing and electrical equipment production.

Key Features and Advantages

  • High electrical conductivity (up to 100% IACS).
  • Excellent flexibility and formability for high-speed cable wrapping and processing.
  • Superior EMI shielding performance.
  • Good tensile strength and elongation for durability during manufacturing and installation.
  • Available in a wide range of thicknesses and widths to meet diverse design requirements.

Shipping & Delivery

International Sea Freight Services

We provide professional and reliable international sea freight logistics services covering major ports worldwide. Whether your cargo is small or large, near or far, we can flexibly arrange the most suitable transportation solution according to your actual needs. Customers are free to choose FOB or CIF (or other Incoterms) to ensure the entire shipping process is transparent, efficient, and cost-effective.

 

Flexible Trade Terms

  • FOB (Free On Board): Ideal for customers who prefer to handle insurance and onward transportation themselves. We are responsible for delivering the goods safely to the designated loading port and completing the loading onto the vessel.
  • CIF (Cost, Insurance and Freight): Perfect for customers who want a one-stop service. We cover the full ocean freight and marine insurance from the port of loading to the port of destination, reducing your operational risks.
  • Other common terms such as FCA, CFR, etc. can also be customized according to your requirements.

 

We maintain extensive sea freight routes and long-term partnerships with major shipping lines (including Maersk, CMA CGM, COSCO, and more). This ensures stable space availability, transparent pricing, and reliable transit times. Whether you are shipping small sample orders or full container loads (FCL/LCL), you will receive professional one-stop sea freight solutions.
