3 main advantages of Sulfur hexafluoride in the power industry

Jan 03, 2017

Sulfur hexafluoride at high temperatures in the reaction of sulfur and fluorine (ie: S +3 F2 → SF6), sulfur hexafluoride at room temperature and pressure for the colorless, odorless, non-toxic gas.

Sulfur hexafluoride in the power industry's main advantages are as follows:

1. Electrical insulation properties and arc-proof performance, insulation properties for the air 2 to 3 times, and the greater the gas pressure, the insulation performance increases. Under the pressure of 294.2 kPa, the dielectric strength of sulfur hexafluoride is approximately equal to that of transformer oil.

2. Sulfur hexafluoride has excellent arc characteristics. Because of its electronegativity, the arc extinguishing capacity of about 100 times the air, especially for high voltage and high current breaking.

3. Due to sulfur hexafluoride gas good insulation properties, so that the device greatly reduced insulation distance, footprint and space volume greatly reduced.
