Standard Arcing Horn

Standard Arcing Horn

High-speed, snap-out arcing horns are standard equipment on all transmission switching applications.  Fabricated from beryllium tube, the rod is tapered to achieve high tip speed during the first cycle after separation.  A black neoprene snubber  attached to two stainless steel support rods is provided to prevent recoil into the open gap during operation.  A copper hook acts as a catcher for the arcing horn during opening, allowing a suitable open gap to be developed before the horn releases with great speed.

Standard arcing horns are suitable for interruption of limited amounts of line charging and transformer magnetizing currents.  In performance, this horn is comparable to horns offered by other manufacturers.
