FAQ
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 to Design and Install a Solar PV System?
Design and Installation of Solar PV SystemsModern society relies on energy for daily needs like industry, heating, transport, and agriculture, mostly met by non-renewable sources (coal, oil, gas). However, these cause environmental harm, are unevenly distributed, and face price volatility due to limited reserves—driving demand for renewable energy.Solar energy, abundant and capable of meeting global needs, stands out. Standalone PV systems (Fig 1) offer energy independence from utilities.
