  • SF6 Circuit Breaker Manufacturer,Supplier,Exporter,Trader

    The SF6 Circuit Breaker is a type of circuit breaker that uses Sulphur hexafluoride gas in order to quench the arc to protect the power distribution systems. This inert gas is colorless, odorless and non-flammable which provides high thermal conductivity. It acts as an insulator and consumes less voltage unlike other breakers, which makes it a cost-effective product.
