The Fuse Must Be Protected Against Accidental Drops Caused By Wind Vibration.

Many drop out fuse are installed on overhead power lines and exposed to natural wind forces. In environments with varying wind speeds, wind-induced vibrations can trigger unnecessary structural movements, potentially causing premature fuse tripping or malfunction.

For installations located near transmission lines, common minor oscillations can cause mechanical wear under continuous load, affecting the tightness of contacts and the overall structural balance. Anti-loosening and vibration-resistant fastener designs are equally applicable to the stable structural design of outdoor fuses.
