FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a sealed dispensing apparatus, having a housing (4) which forms an insulating space (6) and an electrical active part (8, 9, 11a, 11b, 11c) situated in the insulating space (6), said insulating space (6) having an insulation medium. The dispensing apparatus is characterised by that the insulation medium contains a dielectric compound with boiling point higher than -25°C, which is a fluoroketone having 4-12 carbon atoms.
EFFECT: invention increases breakdown field intensity and improves safety.
