Fast, reliable interruption for transformer and line charging currents

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.

Key Benefits:

  1. High tip speed for rapid contact separation
  2. Independent interruption — not dependent on switch speed
  3. Mounts to nearly any vertical or side break switch
  4. Spring-loaded mechanism for reliable operation
  5. Maintenance-free design — only periodic inspection required
  6. Heat-treated, tapered stainless steel whip
  7. Universal mounting brackets included
  8. Long operating life with no performance degradation over time
  9. Backed by Southern States' 24/7 after-sales support and long-life engineering
