Product Details:

The GW9-24 series disconnect switch is suitable for 24kV outdoor AC power systems with frequency of 50/60Hz. It adopts a compact single-pole structure and is commonly installed on poles or crossarms in outdoor distribution networks.

The switch is mainly used to:

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

It is widely used in:

  • rural electrification systems,
  • overhead distribution lines,
  • pole-mounted substations,
  • transformer isolation systems,
  • utility distribution networks.
