Hochspannungs-Grenze-Stromsicherung

The fuse pipe adopts the material with high content of oxidation silicon as the aec extinguishing media,and uses small-diameter metal line as fuse wire.When the overload current or the short-circuit current passes the fuse pipe,the fuse wire immediately is broken ,the electric arc occurs in a few parallel-connecton gaps,the metal steam in the electric arc infiltrates into the quartz sand ,and it is liberated strongly,then quickly puts out the electric arc.Thus,this fuse has good performance an d big breaking capacity.
