Despite its outstanding qualities as an gaseous electrical insulator, it had initially no practical use in engineering. It was only by the end of the 1950s, first in the USA and soon afterwards in Europe that this particular gas was more extensively explored, leading to its principle application as an extinguishing and electrical insulating medium. Commonly used in power applications, insulating gasis used in high-voltage circuit breakers, metal-enclosed switchgear, linear accelerators, high-voltage transformers, capacitors and gas insulated lines worldwide.Get price
