Bushing : It has two parts 1. A hollow insulator may be
filled with oil or air depending on type 2. A conducting
stud or bus bar. Bushing is used to take out/in the power
from a machine without touching the ground parts.
Insulator : It is solid insulated material to isolate one
end (Live) to other end (Ground).
Creepage distance : Just imagine you have one insulator. An
ant starts from one end of insulator to the other end of
insulator. It has to travell on surface of petticoats also.
Distance travelled by ant is the creepage distance.
Hope this will clear your query.

Answer / gunasekaran
bushing also one type of insulator bushing is using for higher voltage application for big transformer we r using condenser bushing bushing it is oil filled insulator there is no oil
creepage distance is distance b/w 2 conducting part along the suface of the insulator for low poluted area 16kv/mm
for moderated 20kv/mm for heavily poluted area 22kv/mm
for industrial 25kv/mm
