This spring-loaded whip attachment increases opening speed and ensures consistent interruption, regardless of switch mechanics.
Southern States' High Speed Whip (HSW) is a performance-enhancing switch accessory designed to interrupt transformer magnetizing and line charging currents. Its spring-loaded design accelerates contact separation, making it highly effective at minimizing arc duration during switch opening.
Unlike standard whip-type interrupters, the High Speed Whip offers maximum reliability — its performance is independent of the switch’s operating speed. Compatible with nearly any vertical break or side break switch, in both standard and slant-style configurations, it’s a versatile choice for utilities seeking enhanced interrupting capability without major equipment changes.
