Vacuum Circuit Breaker (VCB) - Principle, Construction and

Vacuum offers the highest insulating strength. So it has far superior arc quenching properties than any other medium (oil in oil CB, gaz sf6 in sf6 gas circuit breaker).. For example, when contacts of a breaker are opened in the vacuum, the interruption occurs at first current zero with dielectric strength between the contacts building up at a rate thousands of times higher than that obtained withGet price

What is "Sulfr hexafluoride"? | Yahoo Answers

Aug 25, 2007 · Sulfr hexafluoride can be used to insulate the HV leads inside the equipment to shrink the physical size and/or weight of the equipment (compared to air or oil insulated equipment) Arc interrupting equipment that does extinguish the arc in sf 6 gas are often referred to as puffer-type interrupters. These are NOT vacuum interrupters.Get price
