Typically, in India anyway: Dead end station tower, LAs, one to three CVTs, isolator, CT, SF6 breaker, two more isolators, and a structure to expand Bus I and Bus II if not already present. Zebra jumper cables and a dozen strain insulators. And of course ground grid, conduit, relaying, ect.

This is based on a general assumption of what may already in place, in reality your design may deviate from this.

 
why one to three CVT? one per phase?
could you please furnish sld?
 
One per phase- depending on where you pull your step distance and directional voltages (either the bus or line) you will need need 3 line CVTs for the prior, one for the latter. Only one CVT is needed for sync check.


Would these two diagram help?



It shows a wave trap in each bay, however with optical pilot ground wire that is becoming less common.
