  • (DOC) Transmission in 132KV substation | Vishwam Gupta

    SF6 gas has a high affinity of absorbing free electrons as its electro-negativity is very high. Moreover, SF6 is an excellent insulator. The SF6 molecules absorb the free electrons from the arc, and hence form a negative ion. These negatively charged ions have a very low mobility compared to the free electrons.

  • SF6 Circuit Breaker: What Are They? (Types and Operation

    Oct 23, 2020Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.
