Drop-out Fuses Must Be Installed And Replaced By Professionals.

For the drop out fuse protection device used on high-voltage distribution lines and transformers, its structure and installation method dictate that installation and replacement work must be performed by qualified and experienced power maintenance personnel. As an important overcurrent and short-circuit protection device in medium-voltage systems, the 11 kv drop out fuse protection device should be connected to 10kV and higher voltage lines.

Appropriate installation angle, a robust support environment, electrical connections, and insulation isolation conditions are crucial to ensuring that the 11kv drop out fuse protection device can "automatically drop" and form a clear break point in the event of a fault. Installation or replacement often requires the use of specialized equipment such as insulated operating rods, safety belts, and pole climbing tools, and the power supply must be disconnected, a work permit must be attached, and the operation must be strictly followed.
