Abstract
The present disclosure relates to switchgear. Various embodiments may include medium- or high-voltage switchgear with a gas-tight insulating space. For example, a switchgear may include: a gas-tight insulating space where an insulating gas is kept above atmospheric pressure and two switching contacts in the space. At least one of the contacts may movable with respect to a nozzle. The insulating gas may include a mixture of at least 90% by mass of nitrogen and oxygen or nitrogen and carbon dioxide. The nozzle may include a plastic with at least 65% by mass in total of the elements carbon, nitrogen, and oxygen.
