Railway traction substation earthing: what a buyer should define

UPDATE BODY Railway traction substations contain power equipment, protection systems and metallic structures that must be connected to the approved earthing arrangement. Before requesting material, the buyer should share the earthing layout, electrode or rod specification, required length, conductor size, quantity and testing scope. SN Engineering can supply and install 17.2 mm or 20 mm copper bonded rods when these sizes are specified by the approved project documents. The final selection should always follow the railway project drawing and tender requirement. For an accurate proposal, share the approved BOQ or drawing, site location, required quantity and installation scope.
