Was the main reason for the pillars just to carry the power cable or were they intended for security as well? They are quite interesting.

The pillars could have been intended as a barrier as well. The island was primarily used for un positions in the wars, so it could have also been a defensive barrier to stop objects passing through the water, although it probably only gets to about 8 foot deep there.
They look pretty heavy duty!
