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.

Dehydrating Breather Type L Corrosion Resistant Version
We also offer transformer dehydrating breathers as corrosion resistant version with aluminium housing as well UV-resistant C5-M powder coating. For more detailed benefits, kindly refer to benefits at a glance below.

Under normal transformer operating conditions, insulating oil temperature regularly changes with fluctuations in load and ambient conditions. During heavy loading conditions, the oil temperature rises, which causes an increase in oil volume inside the transformer. On the contrary, under light loading conditions, oil temperature cools causing a decrease in oil volume. In a conservator-style transformer, this movement of the oil level causes what is referred to as the transformer “breathing” cycle, as air is brought into the tank and then expelled again later.
