Transformer dehydrating breathers are being used for liquid immersed transformers in order to protect the insulating liquid and prevent the harmful moisture absorption from ambient air, which occurs when the load on the transformer fluctuates.The transformer dehydrating breather removes practically all moisture from the air that flows through it into the conservator when the transformer is cooling down. This largely prevents any reduction of the dielectric strength and the formation of condensation in the expansion tank. Thus, the dehydrating breathers increases the operational safety of transformers.
Our dehydrating breathers are either screwed to the transformer or appropriated by a flange. We offer a variety of different breather types:
- Dehydrating Breather Type L (DIN 42562 / EN 50216-5)
- Dehydrating Breather Type A/B/C (DIN 42567 / EN 50216-5)
- Dehydrating Breather Top mounting 1 ½” and M40 x 1,5
- Dehydrating Breather Without oil stop G 1 ¼”
- Dehydrating Breather 0.150 kg (G 1/2″ or G 3/8″)
Our transformer dehydrating breathers meet the requirements of EN 50216-5.
By default, our housing parts are made of die casted aluminiumand have a premium class corrosion and UV-resistant C5-M powder coating. Upon request, we offer the housing parts made of EN-GJL-200 gray cast iron (DIN 42562).
Your benefits at a glance
- Best corrosion protection ensures longest operation
- Attachment parts are either in A2 or A4 quality depending on environmental conditions
- Lightweight aluminium design with premium powder coating.
- Quality indicating silica gel made by BASF in favour of long maintenance intervals upon request
The oil container in the lower part of the transformer dehydrating breathers prevents any contact with ambient air as long as the transformer doesn’t breathe. In order to ensure this permanently, it is absolutely necessary that the oil container is always filled with oil up to the marked line.
