Adopts the structure of full sealing and insulation. The primary live part is enclosed in the stainless steel gas chamber, which is not affected by the external environmental conditions, so as to ensure the reliability and safety of equipment operation and realize maintenance free. Modular design can realize free combination through the built-in bus expansion; compact structure and small space occupation can help to reduce construction investment; the automation solutions enables the customers to build intelligent distribution network conveniently.

Adopts vacuum switch as opening and closing device, SF6 gas is insulated in the same box, which has compact structure, small floor area and beautiful appearance, and can coordinate with the surrounding environment. Due to the concept of full sealing and full insulation, all high-voltage charged bodies and mechanism parts are completely sealed in the main box, and are not affected by condensation and external pollution environment.
