"Insulgrip" hs tubing -- specs?

Best regards, Spehro Pefhany

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,

'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,

remove first three letters of alphabet and the PM is OK.

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.

Best regards, Spehro Pefhany

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.

and how did they get 4 siginificant figures for that datum?

I think it's like the tourist maps where they tell you the distance to a landmark is 3.7282 miles (6 km) away.

They tried metricizing road signs over here, and they made signs with things like "Speed limit 55 MPH/88.513 KPH" and "Exit Lane 1/4 mi./ .402 KM"

Have you ever noticed those top-posted things painted on the roadway?

Well, that last one kinda works either way around... ;-)

I like the pylons on the 747 used to transport the space shuttle. One reads "Attach orbiter here, black side down" and the other reminds "Righty tighty, leftie loosie".
