Q: What is a SF6 circuit breaker?
A:
An SF6 circuit breaker is a type of high-voltage circuit breaker that uses sulfur hexafluoride (SF6) gas as the arc extinguishing and insulating medium. It can safely interrupt electrical current and isolate electrical circuits.
Q: What is SF6 used for?
A:
SF6 (sulfur hexafluoride) is mainly used as an arc extinguishing and insulating medium in high-voltage electrical equipment like circuit breakers, switchgear, and transformers. It's also used in some types of high-voltage transmission and distribution systems, and in some industries for leak detection and as a tracer gas due to its stability and unique properties.

How does a transformer work?Transformer Operation PrincipleA transformer is an electrical device that operates on the principle of electromagnetic induction to transfer electrical energy from one circuit to another. It enables the adjustment of voltage levels within an alternating current (AC) system, either stepping up (increasing) or stepping down (decreasing) voltage while maintaining the same frequency.Working Principle:Basic ComponentsA transformer consists of two coils, known as windings—the "primary winding" connectRockwell09/03/2025 -
