25mm copper tape is a highly conductive, annealed copper strip. It is commonly used for electrical earthing, lightning protection, and electromagnetic interference (EMI/RFI) shielding. Available in both thin adhesive rolls and thick metallic strips, its flat design provides superior current-carrying capacity and surface area.The specific description and application depend on the type of 25mm copper tape you are looking for:1. Thick Earthing and Lightning TapeTypical Dimensions: 25mm width by 1.5mm to 3mm thickness (commonly 25mm x 3mm).Material: 99.9% pure, high-conductivity annealed copper.Primary Uses: Down-conductors for lightning protection systems, grounding for electrical switchgear/transformers, and equipotential bonding within buildings.
