Summary:Embodiments relate to an insulation assembly for use in a transformer, a transformer assembly for use in a transformer, and a dry type transformer. The insulation assembly includes a plurality of tubular insulation barriers adapted to be arranged around a transformer inner coil to electrically isolate the inner coil from a transformer outer coil, each pair of adjacent tubular insulation barriers being separated by a gap; and an air blocking element arranged in at least one gap between the plurality of tubular insulation barriers to at least partially block an air flow from passing through the at least one gap. According to various embodiments, the air blocking element blocks the cool air from passing through the at least one gap. Thus, more cool air may pass through gas channels near to the inner/outer coils and take away more heat generated by the transformer, thereby improving the cooling efficiency of the transformer.
