I have some Belden 8866 that is old scrap from when I worked in Telcom industry. So I am going to use it to make my test leads for my 5000V Multimeter set up. I only have enough to make the leads. I am guessing that unless things have changed in the last 10 years you have to buy 100 feet minimum from most supplier.
8866 is gross overkill for an amp that will never see ac/dc power above 2700V and never more then 1 amp since it is rated to 40KV. So what do most of you guys use for your HV hookup's inside the amp? Also where is the best place to by small amounts as in under 100feet? Do you go with shielded?If so braided shield or foil? Do you go with high tech high insulation materials or just regular stuff. Would I be right to assume that copper conductor is the norm? I ask because I know that aluminum and nicrome are less like to pick up stray rf, less likely to resonate and introduce parasitic's and are cheaper then copper.....Although the copper market recently corrected itself. Since we are not talking about residential wiring their is nothing barring the use of things like aluminum. Also since space is tight and we are talking about low total volume of wiring in terms of length nothing preventing one from using more expensive Teflon insulation to reduce the thickness of the jacket and make routing easier and still have excellent insulation properties, good resistance to heat and environmental factors as in non-reactive to most industrial solvents and acids in normal concentrations seen in field environment.
No one really mentions conductor material choices, insulation choices, types of shielding and why you may or may not want to shield various power lines etc.....
Given that HV is a beast of a different color compared to anything else most people will wire I thought it merited some discussion as to what you use and why?
