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.

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.

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 higher volt rating. Its also usually tinned conductors
too.

I need to spec battery cable for a nominal 850 vdc LFP bank. Several
brands of power cable list their rating at a dual 600/1000v. it is
my understanding that to be listed in this manner, the cable must
pass a test apply of over 600v for a short period without
breakdown. But under normal operation IMO, the voltage is not to
exceed 600v. And this test is done with AC voltage, not DC.
"*UL 1277: Power and Control Tray Cable*
UL 1277, the standard for electrical power and control tray cable,
was recently updated, allowing manufacturers with UL approved tray
cable to market their 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.
