Answer 1

2.High voltage bushings:

It is the terminals where the primary windings of the the three phase transformer disconnects and this acts as an insulator from the transformer tank. Its size is dependent on the voltage rating of the given three phase transformer.

3.Conservation tank:

An oil stock holding system where the oil in the main tank is separated from the external environment, provided temperature range in the limits specified , by means of an auxiliary tank which is an mediator between this conservator tank and main tank of the given three phase transformer.

4.Radiator:

The heat is generated in oil-insulation inside the main tank of the transformer, the radiator helps to dissipate this generated heat .Generally the radiators are fitted to the main tank of the transformer. The heat generated in the insulation oil is dependent on size of the transformer .

5.Main tank:

This tank contains the three phase transformer windings and the insulating oil.Transformer tanks are to be fitted air-tightly so as to separate this entire setup of windings and oil from the external atmosphere.
