  • the insulator no longer has to be prefabricated, but can now be applied directly to the prefabricated vessel, depending on the design of the switch pole. Since the switch poles are filled independently with the insulating gas, they can also be replaced independently. The provided in the switch amount of insulating can be significantly reduced.
