Generally, High voltage components like circuit breaker, busbar, disconnector and cables etc, are sealed in a SF6 tank at low gas pressure, so the switchgear is not easily affected by external conditions and can be used in harsh environments. The 40.5 kV SF6 insulated switchgear is fully assembled in the factory before delivery, so on-site installation is easy and quick.
Smaller Dimension
With SF6 as the dielectric, it is smaller than oil-insulated switchgear.
High Reliability and Safety
All live parts and switching mechanisms are sealed into SF6 filled enclosure. This kind of switchgear is not easily affected by external ambient conditions, so it is reliable and safe, maintenance-free, and not at risk of electric shock or fire.
Simple Maintenance
Because all live parts and switching mechanisms are sealed in an SF6 tank, they do not rust easily, which reduces maintenance; the vacuum circuit breaker is also maintenance-free.
Flexible Application
Standard modular units and flexible combinations fulfill all requirements of network nodes and terminal users.
Product Features
