Commonly used transformer oils can be divided into 25# 45# and 10# according to the minimum ambient temperature at the time of use:
25# Transformer oil is most commonly used, and its freezing point temperature is -25 degrees Celsius. Can be used in most parts of the world.
45# Transformer oil Secondly, the freezing point temperature is -45 degrees Celsius. It is basically used in cold regions of high north latitude and south latitude.
10# transformer oil, the freezing point temperature is -10 degrees Celsius. Its price is lower than the above two types of transformer oil, suitable for use in subtropical regions.
In addition, the transformer oil can also be divided into oil bases and divided into paraffin groups and cycloalkyl groups. The cycloalkyl transformer oil has a lower freezing point, and usually both the 25# and 45# oils are cycloalkyl.
