Air Break Fuse-Switch

Air- Break fuse switches are installed on low-pressure air power poles and can be disconnected and connected under load by common stick woods in power distribution companies.

These fuse switches are used to maneuver network lines for repairs or modifications, short circuit protection and overload, and quick troubleshooting.

In addition, due to the widespread use of self-supporting cables in the air network and their greater vulnerability to long-term overloads and severe short-circuit currents, it is important to use these fuse switches.




Main line protection by installing at the beginning of the output feeder from the distribution post

Branch line protection by installing at the beginning of the branches taken from the main line.

Selective protection in long networks with installation in the range of 60% distance at the beginning of the feeder.

Consumer protection or temporary connection to a consumer.

Network protection in places where the material of the conductors or their cross-sectional area changes.

Ring the main lines of two different posts by installing at the junction of two feeders as N.O.

Temporary network earthing
