trouble with line side and load side wires


We have three transformers 25okva each and connected thru closed delta connection. Our line side have 6 wires of 25omm each in each transformer. Our main breaker is 2500 Amperes. Our wires at load side is 7 wires of 250 in each line. Our actual load is almost 1800 amperes. What do you think is the problem why our wires from main breaker going to basbar are having hot temperature of up to 80. Anybody who can answer me..

Posting like this make me wonder what is the purpose. Does this even sound realistic? The OP knows quite a bit about his commercial operation and is worried about the temperature of the breaker (2500 Amps) to buss bar wire which is 250mm or 10" in diameter. I believe this is out of scope for this site
