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.
