Audited Supplier TSC series indoor load break switch, whose rated voltage are 12kv, 24kv and 36kv. It adopts SF6 gas as an arc extinguishing and insulation medium.
SF6 is "the" breaking gas offering a number of advantages:# high capacity for carrying the heat produced by the arc. The arc is rapidly cooled by convection during arcing;# high radial thermal conduction and high electron capturing capacity; when the current passes through zero:5 the SF6 permits rapid heat exchange from the centre of the arc towards the exterior,5 the fluorine atoms, which are highly electro-negative, act as veritable "traps" for electrons; since it is the electrons which are mainly responsible for electric conduction in the gas, the gap between the contacts recovers its initial dielectric strength through this electron capture phenomenon at current zero.
