that is the empty weight,
when it gets to the site, they roll in fuel trucks to fill it with oil,
if you tried to ship it with oil it would pop those tires,
those tie down chains are just to keep the cops off your back, they would pop like pop corn if the driver took a corner too fast,
they should have transformer races at Talladega,
i wonder who did the crowbar test, they energize those things then crowbar them (short them out with a big shorting stick) at the peak of the sine wave, this puts a huge amount of DC on the coils,
F=1.257 NI, so maybe 5,000 turns and lets see, 1000 amps per sq inch, so if they use multiple sections on one coil of #4 rect, (rectangular wire), then we are talkin 6,280,000 Gilberts which is enough torque to spin the coil on the core which will snap the leads like a dry twig in a stiff desert wind,
rectangular wire can be torqued down on top of each other with great force, like stacking bricks, but if you nick the enamel from mis-handling, or a factory defect, and squish the wires together, you can get a shorted turn, which will heat up red hot like a branding iron in about 2 micro seconds, that is when the trouble starts, so there is huge stress on the winders to watch the wire as it rolls on, they have their name on every coil so it gets traced back to the guy who wound the wire too close and rubbed off the enamel, which caused the explosion and subsequent oil fire,
those are circular coils so you lay down different sized lams to form a circular core on a big steel rack, then you bolt on huge core brackets that look like i beams and flip the core up, then you lower the coils on with a big hoist,
our foreman was showing the president what a good job they did filling the tank with oil and while he was bending over the tank, a steel ball point pin fell out of his shirt pocket and lodged inside one of the coils, the coils have space between the windings for the oil to circulate and the pen happened to land just right, which means we had to drain the transformer, un hook the leads, hire the crane to come back and pull
the transformer to get the pin out,
i wonder what the core loss is on that thing, probably enuff to run about 5 houses,
is that thing for a Grateful Dead concert or something?
