why are using bus ducts ? why not using cables

Answer Posted / srinu

Normally we wlli use this BUSDUCTS in LV side of the
transformer BcoZ the Current flowing in the LV side is more
than the HV side.

If we use cable we need Large Sq .mm for which cost is more
than to replace a cable. so, it is used. and another thing
is it has high mechanical strength.
