<div class=""><p class="">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. <br class="">

<div id="__MailbirdStyleContent" style="font-size: 12pt; font-family: Arial;" class="">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.

line-height: 22px; text-size-adjust: none;" class="">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."</p>
<div class=""><br class="">

<div class="">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?</div>

<div class="">What do you experienced high voltage battery gurus use in
my application? Thanks.</div>
