Re: [RE-wrenches] dual rated 600/1000v cable for HV battery application

[Kirk Herander]

Thanks Ray,
I am going to use the 2kva DLO cable. It is dual rated as RHW-2, which is what 
inverter OEM recommends. AWC warehouse is also close by in PA. also.

Its also usually tinned conductors too.

product as 600V/1kV rated. To be dual rated, products must use a recognized 1kV 
rated conductor and pass a higher voltage AC Hipot test on the completed cable. 
This test requires each insulated conductor in finished cable to withstand a 
specified voltage range for one minute without breakdown. If a product passes 
the AC Hipot test, it is suitable for 1kV use."

Am I getting this right? And If so, one should not use this 600/1000v wire if 
normal operating voltage is above 600v as is my case? Proper rating should be 
dual 1000/2000v like PV wire?

What do you experienced high voltage battery gurus use in my application? 
Thanks.

Re: [RE-wrenches] dual rated 600/1000v cable for HV battery application

[Ray]

I've used it a few times for battery and inverter cables and it works 
just fine.  It just has a thicker jacket so when you heat shrink it at 
the lugs, it looks funny.  Not a serious problem, just get a higher 
ratio heat shrink like 3 to 1, and it should be fine.

I would look at Diesel Locomotive Cable  DLO, which is usually dual 
rated RHH/RHW-2 for us non locomotive folks.  2000 v rated. Its pretty 
easy to work with, flexible, but has a 2nd inner liner that gives it the
