Abstract

The invention relates to a filter bag for holding filtering material located inside a gas-installed housing of the electrical installation. The filter bag is produced from a fabric that is resistant to high temperatures, which eliminates the need for holding devices protecting the filter bag from hot switching gases to be provided inside the compressed gas housing.
