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.
