Advantages

In 0.2 MPa SF6, average flashover voltage of fluorinated insulators increased by 13.5% compared to unfluorinated

Under foreign matter adsorption defects, average flashover voltage of fluorinated insulators increased by 21.5%

At 126 kV, minimum flashover voltage for free metal foreign matter inside enclosure increased by 18.6% for fluorinated insulators
