    Heat Insulator
AI Thread Summary
The discussion centers on finding a durable insulator capable of withstanding high heat and mechanical stress, specifically in a high-impact application. A metal tube with a rust coating is desired, along with a good conductor inside, as copper alone is too soft and prone to flattening. Participants note that while metals are typically conductive, non-conductive coatings could be explored. Key specifications include a maximum voltage of 80 volts and a current of up to 2000 amps in short pulses. The application is likened to a car colliding with a wall repeatedly, emphasizing the need for robust materials that can endure significant forces.

I would like to find an insulator that can work in high heat and take a beating. A strong metal would be nice. It will be taking a beating and it will have to hold the copper in it form or the copper will flattened out

Aren't metals usually conductive?
Silicon rubber is great stuff.
Fiberglass can take a lot of heat.
What are you trying to do?
 
Sorry for the delay
Yes but what I would like is a metal tube coated with rust on the outside and a good conductor on the inside. Copper is too soft and flattened out in a few minutes. The insulation breaks as well

As Carl points out, metals are generally conductive. There might be some coating that could be applied to the metal shape that would be non-conductive (up to some voltage).

Can you list your specifications for this application? What breakdown voltage (or breakdown electric field, since the thickness may not be specified)? Can you define "tough" and "beating"? Is it a compressive load only, or is there a rubbing/frictional action too that it needs to stand up against? What are the shapes of the objects that come in contact with each other?
 
The max voltage would be no higher then 80 volts. The current could go as high as a 2000 amp pulse of about 100th of a second and about 20 a second. These are not fixed the lower the voltage and the higher the current the better.
This unit is going to be like a car hitting a brick wall 20 times a second the copper is going to be beat and flatened. It will also be under high g force. It's like a RAM gun that's 2" long.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
