XGW- 40.5KV SF6 INSULATED SWITCHGEAR
Generally, High voltage components like circuit breaker, busbar, disconnector and cables etc, are sealed in a SF6 tank which has lower gas pressure, thus the switchgear is not easily affected by external ambient conditions, and harsh environment applications are available.40.5Kv SF6 insulated switchgear is whole assembled in the factory first and then being delivered to the site, therefore the on-site installation is easy and time-saving.
Smaller Dimension
SF6 as the dielectric material, smaller than the oil-dielectric material 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, the reliability and safety standard can be guaranteed, therefore, the product is maintenance-free and would not be at risk of electric shock and fire.
Simple Maintenance
Because all live parts and switching mechanisms are sealed into SF6 tank, not easy to rust, thus reducing maintenance work; vacuum circuit breaker is employed which is also maintenance-free.
Flexible Application
Standard modular units and flexible combinations fulfill all requirements of network nodes and terminal users.
PRODUCT FEATURES
- The SF6 is the insulation material which is sealed in a stainless-steel enclosure, fully-insulated and maintenance-free.
- Long life endurance.
- Obvious watchable open contacts.
- Reliable interlock and safer operation.
