Products SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).

  • Design of Ham Vacuum Tube Transmitters

    In the above transmitter measurement, RF envelope voltage (scaled from a sample tap on a dummy load through an attenuator) decreases from 1.85 volts peak to 1.43 volts, and .42 volt change. This represents a power change from 34.2 watts at the leading edge to 20.4 watts at the minimum during every consecutive dot or dash.
