FEATURES OF ENVIRONMENT-FRIENDLY GAS SWITCHGEAR
The material is environmentally friendly,easy to operate and safe to use;
All conductive parts in the switch are installed in a sealed stainless steel gas box,and the shell can be touched safely;
The main switch adopts vacuum arc extinguishing, and the isolating switch adopts a three-position structure;
Adjacent cabinets are connected through insulated bus bars. The secondary circuit adopts integrated control technology and supports data transmission function;
What you see is what you get, the switch panel has reliable closing and opening signs;
The operation hole is designed with an anti-misoperation protection cover, which can support a padlock;
Perfect mechanical and electrical interlock, effectively avoid misoperation;
Comes with an observation window for easy observation of the isolation fracture.
The Technical Specifications of this Environmentally Friendly Gas Switchgear define its electrical and mechanical parameters for sustainable medium-voltage distribution applications. The VACAIR-12/630-25 Gas Cabinet features all conductive parts installed in a sealed stainless steel gas box, ensuring safe touchable enclosure design. This SF6 Free 12kV Switchgear adopts vacuum arc extinguishing for the main switch and a three-position structure for the isolating switch, providing reliable switching performance without SF6 gas. The Environmentally Friendly Gas Switchgear offers adjacent cabinet connections through insulated bus bars, with secondary circuits employing integrated control technology and data transmission support. The VACAIR-12/630-25 Gas Cabinet features what-you-see-is-what-you-get panel design with reliable closing and opening indications, and an anti-misoperation protection cover on the operation hole supporting padlock installation. This SF6 Free 12kV Switchgear incorporates perfect mechanical and electrical interlocking to effectively avoid misoperation, and includes an observation window for easy viewing of the isolation fracture. Each Environmentally Friendly Gas Switchgear is rated at 12kV and 630A, with power frequency withstand voltage of 42kV (between phases) and 48kV (isolation fracture), and lightning impulse withstand voltage of 75kV (between phases) and 85kV (isolation fracture).
