WHAT'S INSIDE Air Break Switch Disconnector (ABS)

AIr Break Switch (ABS) is a common switching device which uses air as the insulation and quenching medium. Air Break Switches (ABS) are widely installed throughout distribution networks for use as both isolation or switching points.

They are usually employed in outdoor installations. Special Arcing Horns are provided to quench the arc which occurs when the current is interrupted. These switches are usually operated by a handle which is located at the ground level. Their operation can also be mechanized.

Air Break Switch Disconnectors are a vital part of any overhead line network, providing crucial points of isolation.

Most overhead line networks are designed so that when a fault occurs or maintenance work needs to be carried out it is relatively simple, by means of a systematic series of switching operations, to isolate a certain section of the overhead line.
