how much sulfur hexafluoride pipes for cables

Sulfur Hexafluoride (SF6) For higher power handling capabilities, sulfur hexafluoride may be used. An increase of one atmosphere of SF6 (15 psig) increases the peak power rating by a factor of 4. An increase of two atmospheres of SF6 (30 psig) increases the peak power rating by a factor of 10. See figure 5.
