sulfur hexafluoride

基本解释

With sulfur hexafluoride gas to double as insulation interrupter and circuit breaker.
以六氟化硫气体进行灭弧并兼作绝缘用的断路器。
For applications where middle frequency acoustic performance is critical (e. g. speech), insulating glass units can benefit from being filled with sulfur hexafluoride (SF6) gas mixtures.
对于那些中频声音性能在其中起着关键作用的应用（比如语音），用六氟化硫（SF6）混合气体填充绝缘玻璃元件大有裨益。

It can be used for interlayer isolation of gas or oil insulation system, especially interlayer insulation and turn-to-turn insulation of sulfur hexafluoride mutual inductors and transformers.
可在气体或油的绝缘系统内作层间绝缘。主要用于六氟化硫互感器和变压器的层间绝缘及匝间绝缘。

On a slightly smaller scale, there's the huge Siemens breaker I saw at the Bonneville Power Administration. (If you're thinking of buying one as an art object, ask your dealer for a Siemens 72.5 kV SF6 sulfur hexafluoride power circuit breaker).
