I am curious about the four cables. Three phase is usually
configured as delta (no neutral), not wye at those voltage
and power levels. HVDC tends to use two condutors, and even
the fairly rare six phase and twelve phase systems don't use
four conductors. Any idea what was going on there?
Perhaps each of the 3 sets included one spare conductor? Between "cost
of digging trench" and "Cost of being down" a high degree of redundancy
might well make sense .vs. saving money on cables at installation time.
