The inboard end of the conductor has a flat face and a hole. Is this bolted to the end of the relevant winding and if so will this require a person to have access to it? As you describe, the case is pressurised to prevent ingress of foriegn matter and I'm curious as to how the mechanical aspects of connection are achieved.
That's the high side transformer bushing. Yes it is insulated however it has an internal conductor to connect to the internal windings and main bus. Was it power factor tested prior to installation?
If I had about 8 of those shipping containers, I could panel the walls of my cabin! Looks like nice stuff! Great video, was the oil in the transformer at that point or will that come later? Thanks Terry
Noooo. The oil is not installed until the unit is sealed. There is a bank of 12 bottles of compressed air. Air pressure is put in the unit at low volume so there is positive air flow out of the hole while the bushing ports are open to prevent dust from going inside. Once all the bushings are in place, a vacuum is pulled then the oil is sucked inside by the vaccum.
Seems like he has his hands and arms underneath the hoisting load. Got to think twice whether doing your job quicker is worth loosing them 🙂

@@spdfreakls1 Cool on the air! I did not know that?
