I have been using Belden 10 KV test prod wire for the last
several years.... comes in red/black. I use both red/black on
everything......... vey flexible.... abot .21" diam.... silicone
rubber. Many fine strands inside. Test V is 29 kv.
Funny thing is, the smaller 5 kv test prod wire has a test V
of 20 kv.... go figure.
My real concern using this stuff EXTERNALLY like between RF
deck and HV supply... or HV supply to an external cap box is
it would appear to be very easy for something to cut through
it. It needs to be re enforced on the outside.
Back in 1976... our local emporium had 40 kv stuff.... but had a
solid teflon dielectric... was stranded inside... and NOT very
flexible.
Anybody know the V rating on RG-303 TEFLON coax ???
My other idea was to place the Belden 10 kv silicone test prod
wire INSIDE some plastic tubing. I also saw VERY flexible
aluminium BX sheath material at home depot. Also saw the
flexible plastic tubing with the slit all the way through
it... to make life easier getting wiring inside it.
I have seen some fellows place the HV supply very close to
the main 200 A breaker panel..... then run longer lengths of
HV wiring... sometimes inside conduit... to the remoted RF
deck. The idea there was to minimize V drops in the 240 wiring.
The peak current every 8.3 msecs in the 240 V ac line is
unreal.... like almost 4-6 X.
