El_Doug Posted July 9, 2011 Report Share Posted July 9, 2011 I've never made an umbilical for this kind of voltage... any suggestions on wire? or can I use any old 600v teflon? Link to comment Share on other sites More sharing options...
A9X Posted July 9, 2011 Report Share Posted July 9, 2011 I'm in for a set of KGSSHV boards, but I can't seem to get to the spreadsheet - it goes into an endless redirect until timeout. Edit: got it to work by slumming and using IE. Link to comment Share on other sites More sharing options...
flibble Posted July 9, 2011 Report Share Posted July 9, 2011 I'm in for an offboard KGSSHV set- spreadsheet has been updated. Just wanted to say- a big thanks to everyone who made this possible, it's much appreciated! Link to comment Share on other sites More sharing options...
Lil Knight Posted July 9, 2011 Author Report Share Posted July 9, 2011 I've never made an umbilical for this kind of voltage... any suggestions on wire? or can I use any old 600v teflon? navships is the normal suggested source for teflon wires. His stuffs are rated 600v. Link to comment Share on other sites More sharing options...
luvdunhill Posted July 10, 2011 Report Share Posted July 10, 2011 I'd recommend finding something labeled by Alpha or Belden. I don't trust wire unless it has a printed rating on the sleeve. Also, you can add heat shrink or teflon to the wire if you want to be extra certain. Link to comment Share on other sites More sharing options...
Currawong Posted July 10, 2011 Report Share Posted July 10, 2011 (edited) navships is the normal suggested source for teflon wires. His stuffs are rated 600v. Now if they'd sell the braided stuff using a couple of different colours instead of the same colour, it'd be perfect. I already bought a bag of 2m lengths in mixed colours of 600V generic "Kyouwa" wire anyway. Edited July 10, 2011 by Currawong Link to comment Share on other sites More sharing options...

Could not fine anything cheaper. http://ampbuildersparts.com/store/index.php?main_page=product_info&cPath=34&products_id=293 Link to comment Share on other sites More sharing options...

kevin gilmore Posted July 10, 2011 Report Share Posted July 10, 2011 The ratings on the 600V wire is 600V AC. Which just barely works at max voltage swing. At least the teflon stuff i use is rated that way. Link to comment Share on other sites More sharing options...

At least the teflon stuff i use is rated that way. It's hard to infer AC ratings from DC ratings and vice-versa though, at least that is what I've found. Regardless, unmarked wire is a dice roll in my book. Link to comment Share on other sites More sharing options...
kevin gilmore Posted July 11, 2011 Report Share Posted July 11, 2011 The wire i used is actually labeled. At least some of the colors were labeled. If its actually teflon, and nothing else is as slippery and hard to strip as teflon, then if its the right gauge, its likely to be 600V. The much higher voltage stuff is definitely available, but seems to be only available in red. Link to comment Share on other sites More sharing options...
DigiPete Posted July 11, 2011 Report Share Posted July 11, 2011 (edited) I am waiting to see if anyone can get the original DynaFet group buy boards working, not going to invest in another DynaFet board at least until it becomes apparent all attempts to get a reliably stable group buy board have been abandoned. That said, I would rethink a new DynaFet group buy board, as the a second group buy board may run into the same stability issues as the first attempt. I would like to see several successful builds of a prototype DynaFet before I would consider investing Edited July 11, 2011 by DigiPete Link to comment Share on other sites More sharing options...

Currawong Posted July 11, 2011 Report Share Posted July 11, 2011 You do realize that we're talking, what 1.7kV Vpp here? I didn't realise there were different ratings for AC and DC. Checking the packet of what I got, it says 600VDC and 750VAC. I can get, locally, just about any spec power wire (maybe not overhead power line spec, but not far off it) and I'm certainly not interested in stopping my heart through an accident the result of bad wiring. I was thinking aloud about the braiding as I'm pondering whether I'll try bothering with the hassle of a two-case build. Link to comment Share on other sites More sharing options...

Milosz Posted July 11, 2011 Report Share Posted July 11, 2011 I'm a latecomer here, but I hope not too late.... Put me down for a set of T2 boards, if it's possible to get them ..... Link to comment Share on other sites More sharing options...
El_Doug Posted July 11, 2011 Report Share Posted July 11, 2011 Is there a reason to get more then one set of the same board? 1) make more than 1 amp 2) just in case you manage to fry it, scorch it, lift traces, snap it in half.... Link to comment Share on other sites More sharing options...

Pars Posted July 11, 2011 Report Share Posted July 11, 2011 Yep. Ours got knocked out for an hour or so, but was back by 11 or so. Sucks that yours might be out for that long KG... hope they get it fixed sooner. Link to comment Share on other sites More sharing options...
