1.Environmental protection: no SF6 gas, no pollution to the environment, and because it is designed without SF6 gas, it can adapt to colder, higher altitude, more enclosed space and high salt pollution area.
2. Miniaturized design, saving space and supporting construction costs
3. All parts are sealed, the protection level is IP67
4. The operating mechanism is completely sealed, and the maintenance-free design is truly maintenance-free.
5. Multiple interlocking functions to achieve five-proof requirements
6. Advanced and stable protection selection
7. Multiple safety measures to ensure: multiple measures such as visual fracture and reasonable phase separation design
8. Modular design, multiple combinations, easier to change the program
9. High quality assurance and perfect after-sales support
