Air Type Load Break Switch

The Sangao High Quality Air Type Load Break Switch features arc breaking capability, easy maintenance, and scalable design to meet complex power grid requirements. We fully implement ISO9001, ISO14001, and OHSMS18001 quality management systems and maintain long-term cooperation with institutions such as Xi'an High Voltage Research Institute. We not only manufacture switches, but also integrate reliability into every component.

The Air Type Load Break Switch is designed specifically for indoor and outdoor distribution systems ranging from 11kV to 24kV, providing an economical, efficient, and low maintenance solution for switch operation under normal and fault conditions. It uses compressed air as insulation and arc extinguishing medium to ensure safe disconnection, smooth operation, and enhance the visibility of system protection.

Main features and advantages

The Air Type Load Break Switch utilizes air isolation contacts to eliminate risks associated with oil or SF ₆ systems - no leaks, no greenhouse gas emissions, and no need for refilling.

The Air Type Load Break Switch is capable of breaking rated load current and small fault current, with high arc stability and minimal contact corrosion.

With intuitive mechanisms and clear on/off indicator lights, maintenance personnel can operate with confidence and safety.

The low wear arc contacts and sealed operating unit of this switch can reduce downtime and extend service life - up to 10000 operations.

Provide fixed or pull-out design, and can be integrated with fuses, control devices, and electric mechanisms to achieve automation.

Multidimensional application

Air Type Load Break Switch is used in modern switchgear to enhance network flexibility, support ring or radial configurations, and simplify grid upgrades.

Very suitable for wind farms and solar power plants where stable switching and environmental safety are crucial.

Suitable for the metallurgical, petrochemical, and mining industries, ensuring continuous operation in harsh environments.

Installed in railway, airport, and large residential or commercial project substations.
