develop IR SF6 Transfer for cables

Due to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.

  • Designing at Very High Voltages: Everything Changes

Iteither because the engineer has no choice, or because ita really good and necessary idea. The applications fall into two broad groups: In the realm of "the engineer has no choice," scientific, medical, and physics instrumentation need high voltages in specialized equipment such as X-ray machines, to develop high-intensity fields, ionize atoms, and accelerate electrons and other particles. The same applies to vacuum tubes that still need high-power broadcasting or even moderate-power microwave and mm-wave transmitters. In a more common application, even a commercial neon sign needs several kV to ionize the noble gases inside. Note that many of these applications require kilovolts and more, but at relatively modest currents of around 100mA.
