3M Shrink Tubing Insulation numbers?

[DaveC]

3M's data sheet (from Digi-Key):

<http://rocky.digikey.com/WebLib/3M/Web%20Data/EPS-300%20Tubing.pdf>

says that the EPS-300 tubing's insulation rating is 700V/mil. The 3/16 tubing
is 0.020 inches (20 mils) thick, when shrunk, which means it's rated to over
14000 volts?

That just seems a bit high. Is this right?

I simply need about 1500 v insulation for CCFL inverter wiring in a laptop...
Thanks,

So you found a product that is overkill for your application.

Probably. 3M is good stuff - I've personally and non-officially done
some high-pot/TTD testing on it where the normal, low voltage variety
held to 30KV, and one would want the rating to have a safety factor.
Mind you, mine was a quick and dirty lab test with a high voltage supply
and wires, not any sort of standard test jig, whatever that may look
like. It was also 20 years ago - but it certainly puts the number in the
right ballpark.
