24-27kV Porcelain Drop Out Fuse Cutout

Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. They are installed on the high voltage side of the distribution transformer or on the branch line of the distribution line, used as a short circuit of the transformer and the line, overload protection and cut out load current.
Dropout fuse is composed of two parts:An insulating bracket and a fuse tube. The static contact is installed at two ends of the insulating bracket, the movable contact is installed at both ends of the fuse tube, and the fuse tube is composed of an inner arc extinguishing tube and an outer layer.
It consists of a phenolic paper tube or an epoxy glass tube. The load drop fuse enhances the elastic auxiliary contact and the arc extinguishing cover to divide and combine the load current.
