Hi Jim, all,

Yes and my main utility fuse is rated at (3x) 100A, which
would supply me with 114kW of power on a 3 phase
pole pig. So the power is there, but I would need to rectify
the pig output, build a charging reactor and all the stuff
that goes with a DC TC setup, which really complicates
the whole setup. You just canīt beat a single phase AC
coil on hook-up simplicity ;o))

I thought of that. Bill the Arcstarter went to the trouble
to find out some U.S. postage info for me. Turned out
that shipping it per 3rd class boat mail would have cost
3.5x as much as the pig itself (already stripped of oil
and metal housing). Plus, I would have had to pay taxes
on it, here in Germany (16%) and customs, which I have
no idea how high they would be (itīs some 6 odd % for
car parts ;o)).

Yes, I have read that, but in the States you can find them
as surplus, which really drops the price. Looking at some
of the webpages (like Billīs or Bertīs) makes me really
drool over the prices they paid for their caps ;o))

Could be. The only switches I have seen from old overhead
power lines (nowadays they run the lines underground) are
simple mechanical knife switches with big contacts. No arc
suppressing mechanism at all. Of course, I havenīt visited
any large distribution stations, where, AFAIK, they still use
SF-6 filled housings. SF-6 does have itīs disadvantages,
too, tho (esp. when it comes to clean-up time).


Coiler greets from Germany,
