Title:

Current Interruption in SF6-free Switchgear

 

The Technical Brochure of WG A3.41 deals with the technology, availability and application of SF6-free transmission and distribution switchgear. It focuses on the mainstream of upcoming SF6-free current interruption technologies, on the one hand based on interruption in natural-origin gases and their mixtures with fluoronitrile (C4-FN), fluoroketone (C5-FK), and on the other hand based on technical air-insulated vacuum circuit breakers. Despite the different physical characteristics of the SF6-free alternatives, minor modifications enable similar performance, application range and size as their SF6 equivalents, at present up to 170 kV. Products and (pilot) projects with SF6-free switchgear are reported in this Technical Brochure.
