Just How Big is 3", Anyway ?

When we say 3" Transmission Line, we mean Solid Copper Pipe which is really 3-1/8" in diameter. This has a 1" copper 'Inner' conductor. Here's the line next to a 3-1/4" floppy disc for a size comparison... This line can carry 100,000 watts .
( we need a 100 % safety factor)

The Copper Cables and the clamp on the lower left are the splices used to carry power into the transmitter. 480 volts, 3 phase, at a current of about 100 amps.
