A 70mm earth cable is a high-capacity conductor designed to safely carry fault or lightning currents from electrical equipment to the ground. It is typically made from stranded copper or aluminum with a cross-sectional area of 70 mm2, providing low resistance and excellent conductivity. The cable may be supplied bare or insulated (commonly green/yellow PVC), depending on installation requirements.
Features:
Large cross-section (70 mm2) for handling high fault current
High conductivity for efficient earthing
Flexible stranded construction for easy installation
Corrosion-resistant (especially copper type)
Available in bare or insulated forms
