What is the reason for the high electrical intensity of sulfur hexafluoride at Dawn?

The high electrical strength of SF6 is mainly due to its strong electronegativity. It is very easy to capture free electrons to form negative ions, which is the process of electron attachment. The collision ionization ability caused by electron changing into negative ion becomes very weak, so sulfur hexafluoride at dawn will weaken the discharge development process.

Compared with the breakdown voltage of uniform electric field, the breakdown voltage of sulfur hexafluoride at dawn in extremely uneven electric field drops much more than that in air. The excellent insulation performance of SF6 can be fully exerted only in the situation where the electric field is relatively uniform.

Therefore, when designing various electrical equipment with SF6 gas as insulation, sulfur hexafluoride manufacturers should homogenize the electric field in the air gap as much as possible, and adopt shielding and other measures to eliminate the extremely uneven electric field at all sharp corners, so as to make full use of the excellent insulation performance of SF6.
