High Voltage Switchgear SF6 Maintenance equipment for mining

High Voltage Switchgear SF6 Maintenance equipment for mining

When we design switchgear equipment, our objective is that the equipment will have an insulation life upwards of 30 years when applied in a reasonably conservative manner in the usual service conditions defined in ANSI standards. Of course, the quality of maintenance and the installed environment will have a very significant effect.

  • SF6 gas in medium-voltage switchgear | TD Guardian Articles

    In this issue, we discuss the use of SF6 (sulfur hexafluoride) gas in medium-voltage switchgear. SF6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses SF6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
