Product Feature Description
• Compact size
- SF6 gas insulation results in a small enclosure size
- The compact switchgear saves construction land and space,
significantly reducing total investment costs
• Plug-in design for rapid installation
- Busbar connections use plug-in technology, eliminating the need for gas recovery and refilling
operations
- Plug-in technology is used for connecting cables, voltage transformers, and surge arresters
• Modular design for easy expansion
- Single busbar system for single-pole and double-pole 25 kV system applications
- All live parts are fully enclosed in a gas-filled compartment, unaffected by the environment - Easy to implement various configurations
• Comprehensive mechanical interlocking to ensure safe power system operation
- Complete "five-prevention" mechanical interlocking to prevent operator misoperation
• Easy operation and maintenance-free
- Reduced maintenance requirements, saving operating costs
• High-quality material selection with high reliability
- Enhances product reliability and extends product service life
• High structural strength, resistant to internal arc faults of 31.5 kA/1 s, meeting
IAC class AFLR
- Each independent gas compartment is equipped with a dedicated pressure relief channel
