SF6 gasplant DETERMINATION Siemens

Hermetically sealed systems with clean air as an insulating gas take up more space than sf6, but combined with digitalised current and voltage transformers these systems can be built as small as current sf 6 systems. In addition, they are durable and can be used without any problems at the lowest temperatures - down to -50
