Moisture Holders DIN 42567 ( Dehydrating breather ) removes practically all moisture from the air which flows through it into the conservator when the transformer is cooling down. This has the effect of largely preventing any reduction of the dielectric strength of the insulation due to moist ambient air and any formation of condensation in the conservator. Thus the dehydrating breather increases the operational integrity of the transformer. The dehydrating breather is availible for 1 kg and ½ kg filling capacity.

Dehydrating breathers are utilised in liquid cooled transformers. The dehydrating breather removes practically all moisture from the air which flows through it into the conservator when the transformer is cooling down. This has the effect of largely preventing any reduction of the dielectric strenght of the insulation due to moist ambient air and any formation of condensation in the conservator. Thus the dehydrating breather increases the operational integrity of the transformer.
