Excel Earthings

Lightning Protection Conductors made of Electrical Grade Aluminium Alloy with cross sectional area of 50 sq.mm confirming to IS/IEC 62305-3 and IEC 62561-2 are designed to conduct lightning current between the air termination and the earth termination system. Insulated Down conductors are also available, where separation distance, flashover is a concern and to minimise the risk of Touch Voltage.
