Does the current density of ABB transformer windings differ with size and application?

From the brochures available online, it can be assumed that the current density (J) of the winding be different for Helical type and disc wound transformers. What are the approximate values for current density of AB transformer windings?

Richard Mucha, Global Marketing Manager

ABB's answer

Current density in a winding is determined by a number of criteria such as the cooling method, the material used in the winding, the ambient and temperature rises, and as such is very particular to each transformer. ABB utilizes a wide range of current densities based on the above and the load profile the transformer is likely to experience.
