3DN4 Vertical break disconnectors

The current path of the vertical break disconnector opens in the vertical direction, making small phase distances possible. Vertical break disconnectors carry out two movements: a vertical swinging movement, and a rotary movement around its own longitudinal axis.

 

Main features and advantages:

  • The great distance between the supporting and rotating insulators ensures the dielectric strength of the parallel insulation, even in saline fog conditions
  • Delivered in finished assemblies, reducing the time required for installation and commissioning
  • Available with self-interlocking mechanism and in various colors
  • Tested according to national and international standards, such as IEC, ANSI, GOST R and GB
