Improve Fuse Insulation Structure

In many industrial and power distribution systems, drop out fuse not only needs to have accurate fusing characteristics, but also needs to have a reliable insulation structure. A fuse typically consists of a fusible element, an insulating shell, and a support. The insulating shell is responsible for supporting the internal conductive elements and isolating live parts; its materials, dimensions, and manufacturing process have a profound impact on the overall safety of the fuse.

In high-voltage or high-voltage applications, the rated voltage of a fuse is closely related to its fuse tube length and insulation strength. Fuses of the appropriate specifications should be selected based on the circuit voltage during design. Improper insulation design, such as using unsuitable insulation materials or reducing the insulation distance, can lead to flashover or breakdown.
