Advantages of solid insulated ring main unit

Sep 17, 2020

Application in low temperature and cold areas: SF6 gas is eliminated, and there is no need to consider issues such as the liquefaction of SF6 gas at low temperature.

Coastal areas with high salt fog, high humidity, and strong wind and sand: strengthen the steering protection series of products to ensure long-term application under harsh conditions.

Application in plateau area: cancel the SF6 air box, there is no need to consider the deformation of the box caused by the pressure difference between the inside and outside of the air box.

Safe and explosion-proof applications: phase-to-phase isolation design to avoid interphase or multi-circuit short circuit; vacuum interrupter is an explosion-proof product, and the switch sleeve is further protected to strengthen its explosion-proof performance and is suitable for explosion-proof applications.

Implementation of distribution network automation: Built-in Shuangjie Electric DA9000 distribution network automation series products or optional other products can easily realize distribution network automation.

Low-lying areas and manned cable trench applications: The relative density of SF6 gas is five times the relative density of air in the same state. The leaked SF6 gas and its decomposition products are not easy to diffuse and will accumulate in low-lying areas. If there are people working in these areas, it will cause harm to people and suffocate people.

Frequent operation site application: The mechanical life of the solid ring main unit exceeds 10,000 times.

Application in areas with high environmental protection requirements: The impact of SF6 gas on atmospheric warming has attracted great attention from environmental protection departments. In such areas, the application of SF6 gas has been cancelled by the solid ring network cabinet.
