The duct only goes around the fiber, not the MV Cables... So for this question - we can probably ignore the presence of the fiber in duct as we may need to run that fiber line separately anyhow.
We have traditionally open trenched/backfilled or plowed our medium voltage runs from inverter to inverter (approximately 1000 LF). We are looking at utilizing a horizontal directional drilling for our triplexed MV cables (1/0-1250 KCMIL) + ground + fiber in duct. We would drill a 4" bore hole...
