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.
