Transformer Dehydrating Breather Type L

The dehydrating breather type L is used to dry the intake air of transformers.
If the operating temperature of the transformer drops, air will be sucked in through the oil container, cleaned of dirt particles and subsequently dried by the silica gel inside the assembly groups B1 and B2 (optional).
The oil trap prevents any permanent contact between the silica gel and the moist ambient air and also filters the inflowing air. If the temperature rises, air is expelled from the conservator and flows through the transformer dehydrating breather type L in the opposite direction. The size of the dehydrating breather which has to be used depends on the oil volume and the frequency of the air exchange.
Transformer dehydrating breather type L consists of at least one upper part (B1) and the oil trap (OV). Depending on the requirements, further intermediate parts (B2) can be added which are filled with 1.2 kg of silica gel each.Upon requestthe connection parts are available in A4 stainless steel.
