SF6 dielectric strength

SF6 dielectric strength

(OP)
I am searching for information in relation to the dielectric strength of SF6 in kV/mm. Please suggest publications that have the answer or tell me the answer. Thank you.

RE: SF6 dielectric strength

Suggestion: Visit
http://www.usbr.gov/power/data/fist/fist5_9/5_9_1.htm
for:
1.1.2. Dielectric Strength. Its dielectric strength is 2 to 3 times that of standard air and has high thermal stability. The dielectric increases with increasing pressure and at 3 atmospheres, the dielectric strength is roughly equivalent to insulating oil. These properties make it useful in gas-insulated buses and compartments which contain electrical switchgear components.

An old standard reference is Yew, Matheson Gas Data Book, McGraw-Hill, 2001.
