  • What are the Important Characteristics of SF6 Circuit

    For outdoor Extra High Voltage application, the SF6 has less number of interrupters per pole than Air Blast CB and Minimum Oil CB. Outdoor SF6 CB is simple, less costly, maintenance free and compact. The decomposition products are not explosive and therefore there is no danger of fire or explosion.
