Abstract
An apparatus for the generation, the distribution or the usage of electrical energy, the apparatus including a housing enclosing an insulating space and an electrical component arranged in the insulating space. The insulating space contains a dielectric insulation gas including an organofluorine compound A. The apparatus further includes a molecular sieve arranged such as to come into contact with the insulation gas. The molecular sieve has an average pore size y greater than the molecular size of at least one decomposition product of the organofluorine compound A generated during operation of the apparatus. The adsorption capability of the molecular sieve for organofluorine compound A is lower than for the at least one decomposition product. The apparatus further includes at least one desiccant arranged such as to come into contact with the insulation gas.
