Yes 100% you can directly step down from 33KV to 0.430KV.
You must take care transformer sizing should be as per LV
switchgear available at your end.

Answer / mandeep kumar
Yes it is possible to step down from33/.433kv But it can only depend upon the transformer turn ratio its ht turn will be in large nos than 11/.433kv.

Answer / anas
cuz u have to pass it first on substation (distribution
boards) to make it easier cut and start the current in case
of any fault happened and if u didnt do that damage we will
be easy not just easy very very very easy and cause the
transmission stations to damage and u will loss power when
u transform from 33kv to 430v directly ahuge amount of
current will be in the cable that means very huge cable
besides loads alaways

Answer / amit
FROM AMIT -SOHAM ELECTROWELL (P) LTD NASIK----WELL IF UR
LOAD IS ABOVE 1.5 MVA THEN THERE IS CHANCE OF fluctuation
ON 11KV~433 SO ITS BETTER U SHOUD GO FOR 33KV ~433V

Answer / devesh mishra
yes we can directly step down from 33/.433kv.
the lv side remains constant for 11 or 33kv & hv side
depends on load i.e,
for load upto 1.5 mva 11kv ht line is required,whereas
for load above 1.5 mva 33kv ht line is required
