High-voltage isolator switch 3DN4

vertical

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. • 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 The technology of our products sets international trends. We continuously ensure our high quality through optimized production processes, constant product development and a certified quality management system. • All device/construction types consist of the same basic components and are mostly identical: • Current path • Contact system* • Supporting insulator* • Rotating insulator* • Base frame • Connecting rods** • Drive
