  • COLD-WEATHER APPLICATION OF GAS MIXTURE (SF6/N2,

    We have been purchasing mixed-gas circuit breakers since 1988. These initial circuit breakers were purchased with a 0.5 MPa mixture (0.31SF 6 + 0.2N 2) at 20 oC. In 1990, a new gas mixture of SF 6 and CF 4 became available. This new mixture offered some very important advantages over the SF 6 and N 2 mixture. A circuit breaker filled with the SF 6/CF
