DSY-12/24-RMU SF6 Gas Insulated Ring Main Unit (conforming to State Grid and Southern Grid’s standards for integration of primary and secondary systems and standardized customization) has obtained a type test report from the National High Voltage Apparatus Testing Center and has been classified as a high-tech product. It is widely used in 12kV/24kV distribution systems and is the preferred switchgear product for various urban and rural users’ power distribution systems.
The SF6 gas-insulated switchgear is a completely sealed system, with all live components and switches enclosed in a stainless steel shell. This ensures that the entire switchgear is unaffected by external environmental conditions, guaranteeing operational reliability and personnel safety, while also making it maintenance-free. By selecting an expandable busbar, any combination can be achieved, resulting in full modularity. The expandable busbar is safely insulated and shielded, ensuring high reliability and safety.
This GIS can also provide automated TV-based solutions, forming the concept of an intelligent switch, while minimizing the amount of on-site installation and commissioning work required.
Complied with GB standards, DSY-12/24 SF6 gas-insulated switchgear is available in both non-expandable standard configurations and expandable standard configurations. With the flexibility offered by full and half-module combinations and its expandability, it possesses exceptional versatility.
Its design lifespan exceeds 30 years under indoor conditions (40°C) and outdoor conditions (-50°C).
