JB-125F6  indoor metal-cladwithdrawable switchgear

Products Description

JB-125F6 compact fully insulated fully sealed common box inflatable cabinet uses SF6 gas as insulation and breaking medium, SF6 gas is non-toxic, tasteless, inescapable, non-explosive, with excellent arc extinguishing performance and insulation performance.  SF6 gas has strong electronegativity, high dielectric strength, insulation strength is 2~3 times of air, green intensity recovery is fast, arc extinguishing ability is 100 times of air, JB-12 series gas inflation cabinet internal compact structure, small volume, saving space.  The gas pressure in the air box is 1 bar, the pressure of the air box is low, and the arc extinguishing ability is strong.
