But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earthatmosphere.

Utility frequency - Wikipedia

In the United States, Southern California Edison had standardized on 50 Hz. Much of Southern California operated on 50 Hz and did not completely change frequency of their generators and customer equipment to 60 Hz until around 1948. Some projects by the Au Sable Electric Company used 30 Hz at transmission voltages up to 110,000 volts in 1914.

Why Is the US Standard 60 Hz? - News

-For transformers, a major component of AC distribution, you require either more steel or copper at 50 Hz (because of the increased flux density at 50 Hz) as compared to 60 Hz. But the steel losses are higher at 60 Hz. Like everything else in engineering, there are compromises to be made.

electrical - Can I use a 50 Hz device in a 60 Hz power

If it says 220 V 50 Hz, itmore uncertain. Many components should work fine, but perhaps some may overheat, not work, or run at the wrong speed. If the alternative is to throw the machine in the garbage, I would try it (with a transformer in order to convert 110 V to 220 V) but unplug it when not in use.
