  • SF6 gas - WIKA India

    The plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas

  • Technical significance of High-Voltage switchgear in

    In order to minimize the emission of SF6 gas, the N2 – SF6 and CF4 – SF6 gas mixture may be used in circuit breaker in future, as the substitute of pure SF6. It must always be taken care of that, no SF6 gas comes out in atmosphere during maintenance of the CB. On the other hand, SF6 circuit breaker has the major advantage of low maintenance.
