Not sure if it will be what you want, but try contacting a producer of block or a fire door. I believe they have to with stand up to 15,0000 for 4 hours.

I suggest contacting some of the leading circuit breaker manufacturers and materials manufacturers, for both test methods and materials. Just google to find them. I witnessed some extremely high current, short circuit tests at one circuit breaker manufacturer. The current was so high that the test facility had to be located across the street from the power generating utility company. The tests would have knocked out power for many city blocks if the tests were conducted at the manufacturing facility! I think they would be able to help you find the right materials for your project if you could get to the engineering department. Also check out the IEEE and SAE professional organizations. --John R.

Looking for ARC Shielding capable of 9,000 degrees F on continuous basis. Anyone know of a non-conductive material i could use?

I'm Monica Mohtasham from Connecticut and I've been dealing with arc flash analysis for the past year on both AC and DC circuits. Although AC analysis is well documented, DC evaluation has not been analyzed by NFPA as of yet and I was wondering if there is anyone else out there that have been trying to sort out how to evaluate arc flash analysis for DC models. I need to do analysis on fuel cells that output as high as 1200VDC with short circuit currents as high as 1100A.
