Detailed Description

Compressed 10 Liter Cylinder Pack Sf6 Sulfur Hexafluoride Gas Used In Electrical Industry Description: SF6 gas is suitable for power equipment, its strong electronegativity, with excellent arc performance, high dielectric strength, at atmospheric pressure for the air 3 times. Under normal atmospheric pressure, the breakdown voltage of sulfur hexafluoride is 2.5-3 times more than that of air, and the arc extinguishing capacity is more than 100 times higher than that of air. The heat transfer performance is good and easy to synthesize, especially when SF6 gas is discharged or arc When the action occurs dissociation. In addition SF6 gas can be stored in a small gas tank, which is due to high pressure at room temperature easy to liquefaction. Specifications: 1.
