GW5 Outdoor Isolation Switch

The GW5 series outdoor disconnect switch is designed for voltage ratings ranging from 12 kV to 40.5 kV.

Suitable for applications such as outdoor substations and overhead lines, it ensures reliable power transmission.

Primarily used for switching operations under no-load conditions, this product is a key component in power system operations.

Featuring a unique V-shaped design, the switch is simple and compact, requiring less installation space than traditional break switches. This greatly simplifies installation; it is not only suitable for ground-level mounting but also highly efficient and reliable for rooftop substation installations. The clear contact gap after opening allows personnel to visually verify the isolation status during inspection and maintenance, thereby preventing accidental energization.

We offer insulator options in both porcelain and composite silicone materials.

For harsher outdoor environments - such as areas with salt spray or heavy industrial pollution - we can customize the design with increased creepage distance to enhance resistance to pollution flashover, allowing users to select the best configuration for their specific needs. Customization based on project specifications, local grid requirements, and pollution resistance standards is also supported. We provide comprehensive OEM services, including options for custom nameplates.

Every unit undergoes rigorous factory acceptance testing, and we can provide detailed test reports from independent third-party laboratories to meet design acceptance requirements for tenders.

Manufactured by Yueqing Jasco Electric, this series is renowned for its high mechanical strength and long service life, offering a highly cost-effective solution for power distribution projects worldwide.
