Fabricating with plastics

Been following the discussion on fabbing HV assemblies with plexiglass. There's another type of plastic called 'Delrin' that's very hard, very durable, has high temperature resistance, and it machines, drills and cuts as easily and cleanly as aluminum (better, in many cases). I used Delrin blocks to fabricate the insulators for a high-current diode isolator bank. While that application was high-current/low-voltage, Delrin's dielectric strength is huge. It's rated for 380V/mil in that regard, and it has a resistivity rating of 1x10 to the 14th ohms per centimeter. I don't see any reason why it would be unsuitable for high-voltage insulator assemblies as well as high-current. Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"
