Earth Switches
AEM IES Extra High Voltage (EHV) Independent Earthing Switches are 3 phase earth switches designed for transmission substation outdoor busbar earthing duty in 330kV & 220kV power transmission networks. Rated up to 50kA for 1 second, with remote automatic operation, the proven safety and reliability of the IES362 and IES245 make them a first choice for a long llife quality independent earth switch. AEM's local engineering team will design structure heights, spacing, insulator options and configuration to suit your site and operating standards.
AEM IES High Voltage (HV) Independent Earthing Switches are 3 phase earth switches designed for sub-transmission substation outdoor earthing duty in power sub-transmission networks from 66kV to 132kV. Rated up to 50kA for 1 second, with remote automatic operation, the proven safety and reliability of the IES145 and IES72 make them a first choice for a long llife quality independent earth switch. AEM's local engineering team will design structure heights, spacing, insulator options and configuration to suit your site and operating standards.
