It has many favourable characteristics that make it an ideal insulation candidate in modern high voltage switchgear: 1. High dielectric strength(about 8 to 9 times greater than air at 5 bar pressure). 2. Electronegativein nature i.e. catch free electrons forming heavy ions with low mobility that prevents an avalanche type of breakdown. 3.
