Answer to Question 1

Transformer cores are made of thin sheet metal strips in the form of a laminate. There are a number of advantages to using thin sheet metal strips. It is far easier to manufacture thin sheets because they can be stamped where the thicker material would have to be cut. Also the voltage induced in the core will cause current, called eddy current, to circulate. Each metal strip is insulated with a thin layer of oxide that resists the flow of eddy currents. This reduces unwanted current circulation through the core and excessive heating of the transformer.

Answer to Question 2

The condensing unit will also need some means of keeping the high side pressure above a minimum value during low outdoor temperatures.
