gis substation refilling cost in Iran

Of the Substations that ITCTransmission Initially Acquired in 2003, four were mid-1970s vintage gas-insulated substations (GIS). The SF 6 gas used as the primary insulating medium for the 120-kV transmission bus and circuit breakers had been leaking since just a few years after the original installation.

Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). GIS systems use fixed, mounted circuit breakers. The sealed mounted breakers are a ‘sealed...
