I mean like drop out fuse is there for pole mounted transformer, what is there for distribution transformer?

They are listed above...

Padmount distribution transformers will typically have internal (under-oil) fuses that are accessible through little ports within the primary connection compartment. There is usually a standard fuse (For overloads; example: Cooper Bay-O-Net fuse) and also a partial-range current-limiting fuse in series.

For pad mounted distribution transformers, do we have fuses in high voltage and low voltage side?

Best regards,

Is this a homework or general interest question?

Can you explain what you are really after, this is not for an actual real world site is it.

Yes:

• The vendor of the <...transformer...> can. It's only a phone call.
• A Senior Electrical Engineer at the facility where the <...transformer...> is being designed can. It's only a phone call.
• A Senior Electrical Engineer at the facility where the <...transformer...> is installed can. It's only a phone call.
• The "for construction" and "as built" drawings for the installation can. It's a document search. Drawing Office Clerks can. It's only a phone call.

So there's at least four people.

^{Can somebody please tell how is pad mounted distribution transformer of 630 kVA protected?}

Very carefully by someone who knows what they are doing...
