Features:
- The switchgear is designed with a metal-enclosed, box-type structure, providing safety and reliability.
- It is divided into compartments such as the breaker chamber, busbar chamber, cable chamber, and relay chamber, each separated by steel plates,
- The switchgear is equipped with a pressure relief aisle, internal lighting, and top busbars.
- It features a mature "mechanical five-prevention" system to prevent Misoperation.
- The main circuit breaker options include ZN28A-12, ZN28-12, ZN63A-12 vacuum circuit breakers, with the possibility of other models based on requirements.
- Isolation switches include GN30-10 rotary and GN22-10 high-current switches.
- The switchgear is suitable for single bus, single-bus sectionalizing systems, and can be adapted for double bus systems.
- It meets international standards such as IEC62271-200, IEC694, GB3906, DL404, DIN.VDE0670, and has a reliable prevention function against false-operation.
Operating Conditions:
