Googled but can't find voltage insulating value for HS-105 tubing.

Anybody know the answer? Or point me to the manufacturers web site?

Thanks.

Thanks for that.

Dielectric strength listed as 1083 vpm. What's vpm? Volts per mm? Mil? The
size I'm working with is 1/16 which has wall thickness (after shrink) is
0.020 in (0.51 mm). What's the dielectric strength for this?

Thanks,

It's either volts per meter, or volts per mil.

Hello Dave,

This is probably V per Mil, so this converts to 40 kV/mm (so that is
20kV for 0.51mm).
Is there a safety issue in case of insulation failure? If so, please
familiarize yourself with the basic principles of electrical safety.

Some Keywords: functional, basic, double and reinforced insulation,
over voltage category, installation class, EN60950 (safety for ICT),
clearance, creepage distance.

Best regards,

I would interpret that (using your numbers) that the typical breakdown
would be around 20kV using some standardized test method (eg. ASTM),
so it ought to protect against most static electricity or whatever.

But note that CSA rates it at only 600VAC, and that kind of rating
would be much more appropriate where power and safety are concerned.

If your product has to meet specific safety standards, now would be
the time to familiarize yourself with the actual requirements.

No Wim, no safety issue. Voltage is 300 VCD. I just wanted to know what the
safety margins were.

Thanks to you and the others for your help.
