The High
Velocity Whip (HVW) is a spring loaded arcing
horn providing substantially greater interruption of line charging
currents than traditional or other enhanced horn designs. Provides high speed
contact separation, independent of the operating speed of the switch. The HVW is now available for all SEECO group operated switches, including
side-break and center Vee style switches.
Retro-fit kits for other brands and switch styles will be available in
2009. Contact the factory for additional details. |
