The GW9 series outdoor AC high-voltage disconnector is a 12kV outdoor switching device widely used on 10kV distribution lines and pole-mounted transformer installations. It provides a clearly visible break point during line and equipment maintenance, ensuring personnel safety by isolating de-energized sections from live circuits. It is designed for no-load switching only and is operated from the ground using an insulating operating rod.

Key Features

• Clear Visible Break — The open-blade design offers an unmistakable visual isolation point, a critical safety feature for lockout/tagout procedures during line maintenance.
• Silver-Plated Copper Contacts — High-conductivity copper contacts with silver plating ensure low contact resistance, prevent oxidation and maintain stable current carrying over long service.
• Choice of Insulation — Available with traditional porcelain insulators or silicone rubber composite insulators; the composite option is lighter, shatterproof and highly pollution-resistant.
• Robust Outdoor Construction — Hot-dip galvanized steel frame and stainless steel hardware resist rust and corrosion in rain, salt spray and industrial environments.
• Simple, Reliable Operation — Single-pole structure with spring-loaded self-locking mechanism; easy to open and close with a standard insulating hook stick, with positive on/off positioning.
