Informação adicional

Detalhes do produto:

The GW9-12 series outdoor disconnect switch is suitable for single-phase or three-phase AC 50/60Hz power systems with rated voltage up to 12kV. It adopts a single-pole structure and is operated manually using an insulated hook rod.

The switch is mainly used to:

  • open and close no-load lines,
  • isolate high-voltage equipment,
  • provide a visible air-gap for maintenance safety,
  • support overhead line sectionalizing.

It is widely installed in:

  • rural distribution networks,
  • pole-mounted substations,
  • transformer isolation systems,
  • overhead transmission and distribution lines.
