35mm bare copper refers to an uninsulated, stranded electrical conductor with a cross-sectional area of 35 mm2. Made of high-conductivity annealed copper, it is highly flexible, corrosion-resistant, and provides a direct, low-impedance path to the ground. It is primarily used for electrical earthing, lightning protection, and equipotential bonding.
Key Specifications & Characteristics
Material: 99.9% pure, plain soft-drawn or annealed electrolytic copper
Electrical Properties: Extremely low electrical resistance (typically around 0.5240 Ω/km at 20°C) to ensure maximum current conduction and minimal power loss.
