Why is class A winding insulation is only used in oil filled transformers?

This is because the oil has flash over point at 140 deg.Cl and the winding insulation cannot exceed the flash point of the oil.

What is insulation in transformer?
Depending on the size of the transformer, several different types of insulator are used. These include varnishes, plastics, paper, and fabrics (to insulate the windings), wood (spacers), and oil. Transformer oil improves the insulation value of paper, fabrics, and wood when absorbed by them. The oil has a secondary purpose, which is to cool the transformer.
