Polymer Fuse Cutouts (Drop-out fuses) and load-drop fuses are outdoor high-voltage protection appliances. They are assembled on the high-voltage side of distribution transformers or on branch lines of distribution lines, and are used for transmission lines, overload and short-circuit of power transformers, and for switching rated load currents.

The drop fuse is composed of two parts: an insulating bracket and a fuse tube. The static contact is installed at both ends of the insulating bracket, and the moving contact is installed at both ends of the fuse tube. The fuse tube is composed of the inner arc suppression tube and The outer layer is composed of epoxy glass tube. 
The load drop-out fuse is added with elastic auxiliary head and arc extinguishing cover to divide and combine the load current. When the drop fuse is in operation, the fuse tube is tensioned by the fuse to form the closed position. When the system fails, the fault current causes the fuse to be blown quickly, forming an arc. After the arc extinguishing tube, the arc is hot, and a large amount of gas is decomposed, causing a high pressure in the tube and forming vertical blowing along the pipeline. The arc is quickly elongated and off. After the electric fuse is blown, the lower moving contact loses tension and turns down, the retraction mechanism releases the fuse tube, and the fuse tube falls, forming an obvious breaking position. When the load needs to be pulled, use the insulating rod to open the moving contact. At this time, the active contact is still in contact with the static auxiliary contact. Continue to pull the contact with the insulating rod, and the auxiliary contact is also separated, and an arc is generated between the auxiliary contacts. The arc is elongated in the slit of the arc chute, and at the same time the arc chute generates gas, which extinguishes the arc when the current crosses zero.

"JECSANY" Polymer Fuse Cutouts have stable quality and the products are exported to Southeast Asia, South Africa, South America, the Middle East and other global markets. OEM customization can also be made according to the drawings or samples provided by customers.
